8 cubed as a single power of 2

Answer:

5 hamburgers and 3 hot dogs

Step-by-step explanation:

D = number of hot dogs

H = number of hamburgers

D + H = 8    then  D = 8 - H

1.50D + 1.75H = 13.25

substitute for D

1.50(8-H) + 1.75H = 13.25

12-1.50H + 1.75H = 13.25

subtract 12 from each side

-1.50H + 1.75H = 1.25

0.25H = 1.25

divide both sides by 0.25

H = 5

D = 8-5

D = 3

Answer:

10

Step-by-step explanation:

Because if the number of girls is the same as the boys you just devide 20 by 2 and get 10

The value of variable x in the equation is x = c - k / 3

3x+ k = c

let's find x or make it the subject of the formula,

3x + k = c

subtract k from both sides of the equation

3x + k - k = c - k

3x = c - k

divide both sides by 3

3x / 3 = c - k / 3

Therefore,

x = c - k / 3

Answer:

x = 12

Step-by-step explanation:

x = length of side of square A

'x-3' represents length of side of square B

Perimeter of square A = 4x

Perimeter of square A = 4x - 12

we can set up the following proportion based on ratio of 4:3

4x / 4 = 4x - 12 / 3

cross-multiply:

4(3x) = 4(4x-12)

12x = 16x - 48

-4x = -48

x = 12

Answer:

(s+t)(x) = s(x) + t(x)

(s*t)(x) = 2x³ + 4x²

Step-by-step explanation:

(s+t)(x) = s(x) + t(x)

= x + 2 + 2x²

= 2x² + x + 2

(s*t)(x) = s(x) * t(x)

= (x + 2) * 2x²

= 2x³ + 4x²

Answer:

9x ^2 − 25

Explanation:

( a + b ) ( a − b ) = a ^2 − ^b 2

substitute  a  with  3 x  and  b  with 5:

( 3 x + 5 ) ( 3 x − 5 ) = ( 3 x ) 2 −5^ 2 = 9 x ^2 − 25

( 3 x + 5 )( 3 x − 5 ) =  9 x ^2 − 25

Answer:

9x² - 25

Step-by-step explanation:

(a - b)(a + b)= a² - b²

a = 3x   ; b = 5

(3x - 5 )(3x + 5)= (3x)² - 5²

                        = 3²x² - 25

                        = 9x² - 25

8*7=56

1:8 = 7:56

Answer:

7:56

Step-by-step explanation:

1:8

we need to turn the one into seven. Turn the ratio 1:8 into the fraction 1/8.

multiply by 7/7 to turn the one into seven and 8 into 56

7/56 can now be turned into ratio 7:56. You could omit the turning of the ratio into the fraction at the beginning, but I find it makes it simpler.
