Subtract 8a - 4 from 3a

Answer:

Step-by-step explanation:

[tex]5x - 3 - 7x = 15 - x \\ collect \: like \: terms \: \\ 5x - 7x + x = 15 + 3 \\ - x = 18[/tex]

[tex] \frac{ - x}{ - 1} = \frac{18}{ - 1} \\ x = - 18[/tex]

Answer:

D

Step-by-step explanation:

Put n as 48 and solve.

-11 + (48 - 1)(-3)

- 11 + (47)(-3) = -152

Answer:

(1)155 degrees

(2)135 degrees

(3)105 degrees

Step-by-step explanation:

Let the original angle [tex]= \theta[/tex]

Angle Bisector of the original angle = [tex]\dfrac{ \theta}{2}[/tex]

If the other angle forms a linear pair, then:

The other angle, [tex]\beta=180^\circ-\theta[/tex]

Therefore, the measure of the angle formed by the angle bisector of the original angle and the opposite ray is:

[tex]\dfrac{ \theta}{2}+180^\circ-\theta\\=180^\circ-\dfrac{ \theta}{2}[/tex]

(1)If the angle equals 50°

Then the measurement of the required angle

[tex]=180^\circ-\dfrac{ 50}{2}\\=180^\circ-25^\circ\\=155^\circ[/tex]

(2)If the angle equals 90°

Then the measurement of the required angle

[tex]=180^\circ-\dfrac{ 90}{2}\\=180^\circ-45^\circ\\=135^\circ[/tex]

{3)If the angle equals 150°

Then the measurement of the required angle

[tex]=180^\circ-\dfrac{ 150}{2}\\=180^\circ-75^\circ\\=105^\circ[/tex]

Answer:

Step-by-step explanation:

If you were to complete 4 out of the 24 current homework problems, then I can say that you'd have 5/6 of the problems remaining. This is because 24 divided by 4 is 6, so completing 4 questions counts as completing 1/5 of the total amount of work present. If you want to use whole numbers instead of fractions, you would have completed 4 out of 24 questions and would have 20 remaining

Answer:

y = 49

Step-by-step explanation:

y ∝ x²

=> y = kx²

Where k is the constant of proportionality

k = 1 (We've found this out in the previous question)

Now,

y = ? when x = 7

The above equation becomes:

=> y = (1)(7)²

=> y = (1)(49)

=> y = 49

Answer:

5 options : 2 correct options

: 3 wrong options

first answer : 2/5

second answer : 1/5-1

: 1/4

p( choosing correct answer)

= 2/5 × 1/4

= 1/10

Answer:

0.10

Step-by-step explanation:

hello,

there are 5 answers and 2 are correct

I choose a first answer - the probability to be a correct one is 2/5

then now, there are 4 left answers and only 1 left is correct

the probability to choose the correct one is 1/4

so in total the probability to choose the 2 correct answers out of 5 is

[tex]\dfrac{2}{5}*\dfrac{1}{4}=\dfrac{1}{10}[/tex]

which is 0.10

hope this helps

Answer:

x = 4

Step-by-step explanation:

It is stated that f(x) passes through

(-3, 3), (0, 3), (4, 3)

and g(x) passes through

(-4, -3), (0, 0), (4, 3)

Therefore, both functions pass through (4, 3). That is, the input value x = 4 produces the same output value y = 3 for the two functions.

Answer:

Standard deviation  for the number of people with the genetic mutation = 4.178

Step-by-step explanation:

Explanation:-

Given random sample size 'n' =600

proportion of the Population 'p'=3% or  0.03

Let 'X' be the random variable in binomial distribution

Mean of the  binomial distribution

                              μ = n p

                                 = 600 X 0.03

                                = 18

Mean of the  binomial distribution ' μ ' =18

Standard deviation of the binomial distribution

                                σ = [tex]\sqrt{npq} = \sqrt{600 X 0.03 X 0.97} = \sqrt{17.46} = 4.178[/tex]

Conclusion:-

Standard deviation  for the number of people with the genetic mutation = 4.178

Answer:

(C) 4

Step-by-step explanation:

I am going to solve this by trial and error:

(A) 1

Is: [tex](11)^{3} = 85181[/tex]?

[tex](11)^3 = 1331[/tex]

So 1 is not the digit of N.

(B) 2

Is: [tex](22)^{3} = 85182[/tex]?

[tex]22^3 = 10648[/tex]

So 2 is not the digit of N.

(C) 4

Is: [tex](44)^{3} = 85184[/tex]?

[tex]44^3 = 85184[/tex]

Correct, so the answer is c.

(D) 5

[tex]55^3 = 166375 \neq 85185[/tex]

(E) 6

[tex]66^3 = 287496 \neq 85186[/tex]

Answer:

I think that you would divide all the euros by 1.35 to get the pounds

if thats right then the answer should be £2504.07407408

Step-by-step explanation:

i did this by first getting the hotel price (125 euros per night) and timesing that by 14 as they stay for 14 nights, this gives you 1750

then i converted 1750 to pounds by dividing 1750 by 1.35 to get £1296.2962963

next i did the wifi price (6 x 13 = 78, 78 divided by 1.35 = £57.7777777778)

after that i added those two prices together to get £1354.07407408

the final step was to add £1150 so i got £2504.07407408, and that hopefully should be the answer !

hope this works :)

Answer:A

Step-by-step explanation:

Answer: Letter A

Step-by-step explanation:

Answer:

6 minutes more

Step-by-step explanation:

Time = Distance ÷ Speed

Time = 30miles ÷ 60mph

Time = 30mins

Time = 30miles ÷ 50mph

Time = 36mins

36mins - 30mins = 6mins difference

Answer: 6 minutes

Step-by-step explanation:

Time = Distance / speed

When speed is 60 mph

Time = 30/60 = 1/2 hour = 30 minutes

When speed is 50 mph

Time = 30/50 = 3/5 hour = 36 minutes

Answer:

1.34 feet/seconds

Step-by-step explanation:

Looking at the above question, we would be converting 55 miles per hour to feet per seconds.

From the above question, we are given the following conversion values

1 minute = 3,600 seconds

1 mile = 5,280 feet

55 miles per hour = 55 mile / 1 hour

So,

If 1 mile = 5,280 feet

55 miles = x feet

We cross Multiply

x = 5,280 × 55

x = 290,400 feet

Hence, 55 miles = 290,400 feet

1 hour = 60 minutes

If 1 minute = 3,600 seconds

60 minutes = x seconds

We cross multiply

x = 60 × 3,600

x = 216,000 seconds.

This means

60 minutes = 216,000 seconds

In other to find out how fast is the car is,

Speed = Distance / Time

Speed = 290,400 feet/216,000 seconds

Speed = 1.3444444444 feet/seconds

To the to the correct number of significant figures, the car is traveling at 1.34 feet per second.

Answer:

There is some mistake in the question, because the solutions are x = -1.445 and x = -34.555

Step-by-step explanation:

Given the functions:

f(x) = x² + 4x + 10

g(x) = -32x - 40

we want to find the points at which f(x) = g(x).

x² + 4x + 10 = -32x - 40

x² + 4x + 10 + 32x + 40 = 0

x² + 36x + 50 = 0

Using quadratic formula:

[tex]x = \frac{-b \pm \sqrt{b^2-4(a)(c)}}{2(a)} [/tex]

[tex]x = \frac{-36 \pm \sqrt{36^2-4(1)(50)}}{2(1)} [/tex]

[tex]x = \frac{-36 \pm 33.11}{2} [/tex]

[tex]x_1 = \frac{-36 + 33.11}{2} [/tex]

[tex]x_1 = -1.445 [/tex]

[tex]x_2 = \frac{-36 - 33.11}{2} [/tex]

[tex]x_2 = -34.555[/tex]

Answer:

m = -6

Step-by-step explanation:

3m = -18 (Divide both sides by 3)

3m/3 = -18/3

m = -6

Answer:

m=-6

Step-by-step explanation:

3m=-18

Divide by 3 on each side.

3m/3=-18/3

m=-6

Answer:

£170000

Step-by-step explanation:

In 2010, Rafik bought a house. Let us assume Rafik bought the house for $x.  In 2015, Rafik sold the house to Bianca and made 20% profit. 20% profit = 20% of x = 0.2 × x = 0.2x. Therefore Rafik sold the house to Bianca at x + 0.2x = 1.2x. Bianca bought the house at 1.2x

The house was sold by Bianca at 5% loss in 2019. 5% loss = 0.05(1.2x) = 0.06x

Therefore the house was sold by Bianca at 1.2x - 0.06x = 1.14x. Since Bianca sold the house at £193800.

⇒ 1.14x = 193800

x = 193800/1.14

x = £170000

Rafik paid £170000 for the house in 2010

Answer:

The additive inverse of the polynomial  being subtracted is -0.612-8+181

Step-by-step explanation:

Given expression : (1.32 +0.412 – 241) – (0.612 + 8 - 181)

Now the polynomial being subtracted : (0.612 + 8 - 181)

Additive inverse : The number in the set of real numbers that when added to a given number will give zero.

So, Additive inverse of 0.612 = -0.612

Additive inverse of 8 = -8

Additive inverse of -181 = 181

So, The additive inverse of polynomial being subtracted : -0.612-8+181

So, Option B is true

Hence the additive inverse of the polynomial  being subtracted is -0.612-8+181

Answer:

48x^2 - 22x - 15

48x^2 - 22x - 15

Answer:

Gold weighs more

Step-by-step explanation:

The fact that they both equal 16 oz confirms the fact that gold weighs more. The reason for this is because even if the mass is the same the weight involves the gravitational pull on the earth meaning gold is greater.

1 pound of gold weighs more than 16 ounces of Soda.

We are told that;

Weight of soda = 16 Oz (ounces)

Weight of gold = 1 pound

Now, from conversions between pounds and ounces, 1 pound = 16 oz

Thus means that soda too also has a mass of 1 pound same as Gold.

However, despite the fact that they have the same mass, it doesn't mean they weigh the same because Gold has a gravitational pull which means force of gravity on it from the earth and it means it will weigh more.
