Meaning lees 10 from 20 and multiply

Hi there!

First of all, let the unknown number be z.

Now, subtract 10:

z-10

This expression is equal to twice the same number:

z-10=2z

Solve this equation:

z-2z=10

-z=10

Divide both sides by -1 in order to get rid of the minus sign:

z=-10

Hope everything is clear.

Let me know if you have any questions!

Answer:

1)14oz

2)28oz

Step-by-step explanation:

1) To find the amount of water is left in the bottle you want to substract 1/3 so the first thing you want to do is find what 1/3 of 42 is. So do this: (This is also 42/3)

42*1/3=14

So we now know that 14 is 1/3 of 45 which is the first answer. To find the second answer you want to substract 14 from 42 which is 28.

So that means she has 28 oz of water left when she gets there.

Answer:

0.41

Step-by-step explanation:

S = "she's up all night 'til the sun"

F = "she's up all night for good fun"

P(S or F) = P(S) + P(F) − P(S and F)

0.36 = 0.36 + 0.41 − P(S and F)

P(S and F) = 0.41

Answer:

The answer is "[tex]\bold{11000(0.83)^t}[/tex]".

Step-by-step explanation:

[tex]\bold{ \text{selling price}} = \$ 11,000 \\\\\bold{ \text{loses}} = 17 \%[/tex]

[tex]\bold{\to f(t)= c (1-r)^t} \\\\[/tex]

           [tex]=11,000 (1- 0.17)^t\\\\=11,000(0.83 )^t[/tex]

Answer:

Universal set is 80

Number of people that speak Nepali is 50

Number of people that speak English is 45

Number of people that do not speak both is 7

a. Number of people that speak both languages is 22

b. As above

Step-by-step explanation:

a. Let make number of people that speak both languages x

To get x

(50-x) + (45-x) + x + 7 = 80

(50-x) + (45-x) + x = 80 - 7

(50-x) + (45-x) + x = 73

Open bracket

50-x+45-x+x= 73

50+45-2x+x = 73

95 - x = 73

-x = 73 - 95

-x = -22

x = 22

Therefore, number of people that speak both languages is 22

b. To get venn diagram

Number of people that speak Nepali is 50 - 22 = 28

Number of people that speak English is 45 - 22 = 23

Therefore, total = 28+23+22+7 = 80

Number of $10 bills = 2

Number of $5 bills = 3

Number of $1 bills  = 5

Step-by-step explanation:

Given:

Total amount = $40

Number of $10 bills = x

Number of $5 bills = x + 1

Number of $1 bills = x + 1 + 2 = x + 3

Find:

Number of each bills

Computation:

10(x) + 5(x+1) + 1(x+3) = 40

10x + 5x + 5 + x + 3 = 40

16x = 32

x = 2

Number of $10 bills = x = 2

Number of $5 bills = x + 1 = 3

Number of $1 bills  = x + 3 = 5

Answer:

# of $10 bills = 2

# of $5 bills = 3

# of $1 bills  = 5

Commutative property of addition is a+b=b+a

7+2=9 , 2+7=9

9=9

So, commutative property is true for addition

2-7=-5 , 7-2=5

-5 is not equal to 5

Commutative property does not apply to subtraction

Answer:no

Answer:

There is 5/8 left for Mohamed to eat.

Step-by-step explanation:

Let's put everything into fractions of 1/8. knowing that 25% is 1/4 or 2/8, 1/8 + 2/8= 3/8. and to find the answer, you need to subtract 3/8 from 8/8 or 1.

As a result, 5/8.

1/8 = 12.5%

12.5% + 25% = 37.5%

We need to know how much is left.

37.5% is gone, so 100% - 37.5% = 62.5%

62.5% is left for Mohamed to eat.

62.5% = 5/8.

5/8 of a pizza is left for mohamed to eat.

Answer:

The Student has good posture on the chin rest but The way that there are not standing straight up and how there holding the bow is incorrect

Step-by-step explanation:

Sitting up straight, turn your head enough that your nose lines up with the left foot. Drop your chin and place the violin so that it's also aligned with your left foot. Hold your spine straight and relax into this position; you should be able to keep the violin steady using only your chin.

I'm not 100 percent sure this correct

Answer:

We have the equation:

3x - 5y = 15

a) We want to create a table with at least 4 points.

To do this, first, let's write the equation as a function: We must isolate one of the variables. Let's isolate y.

5y = 3x - 15

y = (3/5)*x - 3.

Then we have a linear equation.

Now, we can input different values of x, and see what value takes y in each case, then in this way we can be sure that the points will be on the line.

x = 0.

y = (3/5)*0 - 3

y = -3

Then we have the point (0, -3).

x = 1.

y = (3/5)*1 - 3 = 3/5 - 15/5 = -12/5

y = -12/5

Then we have the point (1, -12/5)

x = 5

y = (3/5)*5 - 3 = 3 - 3 = 0

y = 0

then we have the point (5, 0)

x = 10

y = (3/5)*10 - 3 = 6 - 3 = 3

y = 3

Then we have the point (10, 3).

Now we can create the table

[tex]\left[\begin{array}{ccc}x&y\\0&-3\\1&-12/5\\5&0\\10&3\end{array}\right][/tex]

Below you can see a graph, where the blue dots are our 4 points, and the green line is the line that represents the equation.

Answer:The reasonable domain contains only positive whole numbers.

Step-by-step explanation: Domain is x-values. X stands for the amount of people. The amount of people can't be negative. There also can't be half a person so it has to be whole numbers. There can be less than 3 people coming.

Answer:

B on edge 2021

Step-by-step explanation:

Answer:

The vertex is (-1, 4), the domain is all real numbers, and the range is y less than 4

Step-by-step explanation:

Given

[tex]f(x) = -(x+1)^2 + 4[/tex]

Solving (a): The vertex;

Assume the general form of a function is

[tex]f(x) = a(x-h)^2+k[/tex]

The vertex is determined by [tex](h,k)[/tex]

By comparison, we have:

[tex]-h = 1[/tex]

Solve for h, we have:

[tex]h = -1[/tex]

[tex]k = 4[/tex]

So, the vertex is:

[tex](h,k) = (-1,4)[/tex]

The domain; x is all real numbers

From the function;

[tex]f(x) = -(x+1)^2 + 4[/tex]

This can be rewritten as:

[tex]f(x) = 4 - (x+1)^2[/tex]

This implies that:

Whatever the value of [tex](x + 1)^2[/tex] is, it will be subtracted from 4 to give y or f(x);

Hence:

y is less than 4

Option B answers the question

Step-by-step explanation:

55 + 20 + x = 180

Quantity of trail mix with Monty = 3/4 pounds

Quantity of pounds he need to divide it into = 1/8

Number of trail mix bags Monty will have =

= 3/4 ÷ 1/8

= 3/4 × 8/1 ( division of fraction is multiplication with reciprocal )

= 24/4

We know that both 24 and 4 is divisible by 4 . Hence ,

= 24 ÷ 4 / 4 ÷ 4

= 6/1

= 6 bags

Therefore , Monty will have 6 bags of trail mix .

Quantity of food an elephant eats in 16 hours = 525 pounds

Quantity of food the elephant will eat in 1 hour = 525 ÷ 16

Quantity of food the elephant will eat in 1 hour = 32.8125 pounds = 33 pounds

Therefore , an elephant eats 33 pounds of food in 1 hour .

Number of tickets that can be purchased with $14 = 1 ticket

Number of tickets that can be purchased with $500 =

= 500 ÷ 14

= 35 tickets

Therefore , 35 tickets can be purchased with $500 .

Factors of 45 = 1 , 5 , 3, 9 , 15 and 45 .

Factors of 27 = 1 , 3 , 9 and 27 .

Their Greatest common factor = 9 .

Then , the sum of 45 and 27 can be written as :

9 ( 5 + 3 )

Therefore , Mr . Morris wrote = 9 ( 5 + 3 ) .

Total number of event flyers in a club = 4896

Total number of playerz in a club = 24

Then number of flyers each member of the club will get =

= 4896 ÷ 24

= 204

Therefore , each player will get 204 flyers .

Part A is not given .

Part B :

= 7950 ÷ 25

= 318

Therefore , 7950 ÷ 25 = 318 .

Answer:

66

Step-by-step explanation:

increase the number by 175% of its value.

percentage increase = 175% × 24

new value =

24 + percentage increase =

24 + (175% × 24) =

24 + 175% × 24 =

(1 + 175%) × 24 =

(100% + 175%) × 24 =

275% × 24 =

275 ÷ 100 × 24 =

275 × 24 ÷ 100 =

6,600 ÷ 100 =

66

Answer:

258.96

Step-by-step explanation:

%30 = 0.3

%6   = 0.06

so..

349 - (349 × 0.3)

349 - 104.7

244.3

then do the tax which is %6 or 0.06

244.3 + (244.3 × 0.06)

244.3 + 14.66

258.96

Answer:

n-k-1

Step-by-step explanation:

n is bigger than k. It asks BETWEEN k and n. so, since n is bigger than k, n-k. since it says BETWEEN, you subtract 1 after that

got it?

=)

oh and the reason i am strict about BETWEEN, is because when it said between, then its discluding k and n.

If it says FROM k and n, then you both include k and n, and that would result of adding 1 instead of subtracting 1.
