f1 = 480

f2 = 800

Solution

Method One: Step by Step

f1 / f2 = 480/ 800

Start by dividing both top and bottom on the right by 10

f1/f2 = 480/10 // 800 / 10

f1 / f2 = 48 / 80

The next thing to notice is that both 48 and 80 are divisible by 8. Divide top and bottom on the right by 8

f1 / f2 = 48 / 8// 80/ 8 =  6 / 10

f1 / f2 = 6/10

Last, divide top and bottom on the right by 2

f1 / f2 = 6/2 // 10 / 2

f1 / f2 = 3 / 5

Method Two Highest Common Factor.

Could you have done this a short way? Yes if we say it. The short way would have been to  divide by 10 * 8 * 2 = 160 right away. We might have done it by factoring 480 and 800 into prime factors.

480: 2  * 2 * 2 * 2 * 2 * 5 * 3

800: 2 * 2 * 2 * 2 * 2 * 5 * 5

The highest common factor is what is in bold.

The highest common factor is 2^5 * 5 = 32 * 5 = 160

The answer in both cases is 3/5 which I think is D.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
