12% of 68 is 8.16. In order to find this answer you must change 12% into a decimal (.12) and then multiply by 68. (68×.12=8.16).

You have to change 12%into a decimal than multiply that by 68.

SO it would look something like this:
68 x .12 = 8.16

your answer:
12% of 68 is 8.16

Which expression represents the prime factorization of 96?

SCORPION-xisa [38]

It is not A. because 8 is not a prime number.

It is not B. because 12 is not a prime number.

C. 2 x 2 x 2 x 2 x 2 x 3 = 4*4*6= 96

D. 2 x 2 x 2 x 2 x 2 x 3 x 3= 4*4*6*3=16*18= 288

Answer is C. -2 x 2 x 2 x 2 x 2 x 3 : 96 ( not D. = 298 , 298 is greater than 96)

The graph shows the relationship between pounds of grapes, g, and their cost, c.

UkoKoshka [18]

Step 1

Let

x------> the cost in dollar

y-----> the pounds of grapes

$A(0,0)\ B(2,1)$

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

The line in the graph represent a direct variation

Find the constant of proportionality k

$y/x=k$ ------> substitute point B -----> $1/2=k$

The slope is equal to the constant of proportionality

$m=0.50\ \frac{pounds}{\$}$

the linear equation is $g=0.50c$

therefore

the answer Part a) is

For every dollar you spend, you can get $0.50$ pounds

Step 2

Find the cost for one pound of grapes

Let

$g=1\ pound$

substitute the value of g in the linear equation and solve for c

$g=0.50c$

$1=0.50c$

$c=1/0.50=2\$$

therefore

the answer Part b) is

For each pound of grapes, you would need $2\$$

Solve for w. 21=-3/8w

goblinko [34]

Answer:

w = -56

Step-by-step explanation:

Solve for w:

21 = (-3 w)/8

Hint: | Reverse the equality in 21 = (-3 w)/8 in order to isolate w to the left hand side.

21 = (-3 w)/8 is equivalent to (-3 w)/8 = 21:

(-3 w)/8 = 21

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (-3 w)/8 = 21 by -8/3:

(-8 (-3) w)/(3×8) = (-8)/3×21

Hint: | Express (-8)/3×(-3)/8 as a single fraction.

(-8)/3×(-3)/8 = (-8 (-3))/(3×8):

(-8 (-3))/(3×8) w = (-8)/3×21

Hint: | Express (-8)/3×21 as a single fraction.

(-8)/3×21 = (-8×21)/3:

(-8 (-3) w)/(3×8) = (-8×21)/3

Hint: | In (-8 (-3) w)/(3×8), divide -8 in the numerator by 8 in the denominator.

(-8)/8 = (8 (-1))/8 = -1:

(-3-1 w)/3 = (-8×21)/3

Hint: | In (-(-3) w)/3, divide -3 in the numerator by 3 in the denominator.

(-3)/3 = (3 (-1))/3 = -1:

--1 w = (-8×21)/3

Hint: | Multiply all instances of -1 in -(-w).

(-1)^2 = 1:

w = (-8×21)/3

Hint: | In (-8×21)/3, divide 21 in the numerator by 3 in the denominator.

21/3 = (3×7)/3 = 7:

w = -87

Hint: | Multiply -8 and 7 together.

-8×7 = -56:

Answer: w = -56

You use the slope-intercept form y = mx to find the y intercept b. Which equals b = 2.
Hope this helped.
