Step-by-step explanation:

ac is the answer

.............

Answer:

x = -15

m = -3

Step-by-step explanation:

3x + 6 = x - 24

subtract the x from both sides to make the unknown variable on only one side of the equation

2x + 6 = -24

subtract the 6 from both sides to focus on the x

2x = -30

now divide both sides by 2 to get the x by itself

x = -15

that's your answer

10 - 2m = 16

subtract the 10 from both sides to focus on the m

-2m = 6

now divide both sides by -2 to get the m by itself

m = -3

that's your answer

Answer:

[tex]B =120[/tex]

Step-by-step explanation:

Given

Represent Kitchen with K and Bedroom with B.

So:

[tex]K = 50ft^2[/tex]

[tex]K = 10 + \frac{1}{3}B[/tex] --- 10 more than 1/3 of Bedroom area

Required

Determine the bedroom area

The expression of K and B has been determined above.

The next step is to substitute 50 for K in the second equaion

[tex]K = 10 + \frac{1}{3}B[/tex]

[tex]50 = 10 + \frac{1}{3}B[/tex]

Multiply through buy 3

[tex]3 * 50 = 3 * 10 +\frac{1}{3}B * 3[/tex]

[tex]150 = 30 +B[/tex]

Make B the subject

[tex]B =150 - 30[/tex]

[tex]B =120[/tex]

Hence, the area of the bedroom is 120ft^2

Answer:

32 pounds of almonds

Step-by-step explanation:

Let the number of pounds of almond be a while that of cashews be c

we want to make a total of 80 pounds

Thus;

a + c = 80 ••••••••(i)

Furthermore;

Let us work with the costs

Costs of a pounds of almonds will be ;

a * 2.5 = 2.5a

cost of c pounds of cashews

c * 3.25 = 3.25c

Total cost at which they sell will be 80 * 2.95 = 236

Thus;

3.25c + 2.5a = 236 •••••(ii)

From i, c = 80-a

Put this into ii

3.25(80-a) + 2.5a = 236

260-3.25a + 2.5a = 236

0.75a= 24

a = 24/0.75

a = 32

Answer:

[tex]y = 1500(0.024)^t[/tex]

Step-by-step explanation:

Given

[tex]a = 1500km[/tex] -- initial area

[tex]b = 2.4\%[/tex] -- rate

[tex]t = time[/tex] --- (years)

Required

Represent as an exponential function

An exponential function has the form:

[tex]y = ab^t[/tex]

Where

[tex]a = initial\ value[/tex]

[tex]b = rate[/tex] and [tex]b \ne 1[/tex]

[tex]t= time[/tex]

Substitute values for a and b, we have:

[tex]y = 1500 * (2.4\%)^t[/tex]

Convert percentage to decimal

[tex]y = 1500 * (0.024)^t[/tex]

[tex]y = 1500(0.024)^t[/tex]

Hence, the exponential function that represents the scenario is: [tex]y = 1500(0.024)^t[/tex]

Answer:

Step-by-step explanation:

sure lizzie  

soo  elimination method just means we want to cancel out on of the variable by subtracting of add the entire equations to each other... there is another method but this one is pretty good to learn with.

system 1

2x + 2y = -2

3x - 2y = 12

since there is already an easy way to get rid of the y variable lets just add the two equations together, just add term by term

5x  + 0y = 10

if you notice .. just by making an imaginary column.. of each term.. you can just do that single piece by it self.... 2x + 3x = 5x   and 2y +(-2y) = 0  and -2 + 12 = 10  :)

so now I can rewrite our new equation

5x = 10    I can solve this one with my eyes closed  :D  (10/5 = 2 )

x =2   :P

now , since we know x  .. just plug in the known value of x into the 1st equations...  

2(2) +2y = -2

4 + 2y =-2

2y = -2-4

2y = -6

y = - 3   :) ( I had to keep my eyes open that time b/c there was a minus sign floating about and those are too easy to mess up on .. when you do.. don't worry everyone does )

so we know

x = 2  and y = -3  :)

I'll go a little faster on 2.. and I see 3 is good for you to practice on.. just ask later if you have questions on that one.

system 2

4x - 2y = -1

-4x + 4y = - 2

add them again to get rid of the x term

0x +2y = -3

y = - 3/2

plug in y

4x  - 2(-3/2) = -1

4x +3 = -1

4x = -1 - 3

4x = -4

x = -1  

they are being nice and making them easy to start out.. you try system 3

Answer:

3/2 or 1 1/2

Step-by-step explanation:

5÷3 1/3

5/1 ÷ 10/3 because you have to get it into an improper fraction form in order to divide

5/1 × 3/10 because you have to multiply the first number by the reciprocal

5  and 10 cancel out so you would have 2 at the bottom

3/2 or 1 1/2

Answer:

3x + 4y = 72

Step-by-step exlanation:

Number of pizzas = x

Number of sandwich trays = y

one large pizza can feed 3 players

one sandwich tray can feed 4 players

Total players = 72

The linear equation is

3x + 4y = 72

Answer:

O B. log4 7-3 log4 x

[tex] log_{4}( \frac{7}{ {x}^{3} } ) \\ = log_{4}7 - log_{4}{x}^{3} \\ = log_{4}7 - 3 log_{4}x[/tex]

The expression  equivalent to the logarithmic expression

log 4 (7/x^3) will be B. log4 7-3 log4 x

A logarithm is the power to which a number must be raised in order to get some other number

log 4 ([tex]\frac{7}{x^3}[/tex])

log 4.7 - log 4x^3  (log (a/b) = log a - log b

log 4.7 - 3 log 4x

correct answer is  B. log4 7-3 log4 x

Answer:

[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]

Step-by-step explanation:

Given the expression

[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)[/tex]

solving the expression

[tex]=-7x^0+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]

apply the rule: [tex]a^0=1,\:a\ne \:0[/tex]

[tex]=-7+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]

[tex]=-7+5x^2-x+6+8x^2-x-3[/tex]

simplify

[tex]=13x^2-2x-4[/tex]

Therefore, the simplified form is:

[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]

Answer:

180

Step-by-step explanation:

so if it is addition like I assume it is, you would do this:

18 +18 +18 +18 +18 +18 +18 +18 +18 +18

that is also equal to 18x10.

so 18 ten times. a simple trick for multiplying by ten is just adding a zero, so 18x10 is 180.

I THINK THIS IS RIGHT LOL

Hey there!

18 * 10

≈ 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18

≈ 36 + 36 + 36 + 36 + 36

≈ 72 + 72 + 36

≈ 144 + 36

≈ 180

Therefore, the answer should be: 180

Good luck on your assignment & enjoy your day!
