Im really confused can somebody explain this?
vovikov84 [41]

<u>Given</u>:

The given ratio is 16 : 12

We need to determine three ratios that are equivalent to the given ratio.

<u>Option A</u>: 8:6

The given ratio is 16 : 12

Let us divide the given ratio 16 : 12 by 2.

Thus, we have;

8:6

Hence, the expression 8:6 is equivalent to 16 : 12

Thus, Option A is the correct answer.

<u>Option B</u>: 32:24

The number 32 goes by 16 in 2 times and the number 24 goes by 12 in 2 times.

Thus, multiplying the ratio 16 : 12 by 2, we get;

32:24

Thus, the expression 32:24 is equivalent to 16 : 12

Hence, Option B is the correct answer.

<u>Option C</u>: 4:3

Let us divide the given ratio 16 : 12 by 4.

Thus, we have;

4:3

Thus, the expression 4:3 is equivalent to 16 : 12

Hence, Option C is the correct answer.

<u>Option D</u>: 12:8

The number 12 goes by 16 in \frac{3}{4} times and the number 8 goes by 12 in \frac{2}{3} times.

The ratios are multiplied by different numbers.

Thus, the expression 12:8 is not equivalent to 16 : 12

Hence, Option D is not the correct answer.

<u>Option E</u>: 24:16

The number 24 goes by 16 in 1.5 times and the number 16 goes by 12 in 0.75 times.

The ratios are multiplied by different numbers.

Thus, the expression 24:16 is not equivalent to 16 : 12

Hence, Option E is not the correct answer.

Therefore, the equivalent ratios are Option A, B and C

3/4(8x-4)=7x+2 This is a linear equation please help!
aleksandrvk [35]

Simplify the left hand side by multiplying the terms in the parenthesis by 3/4, i.e. divide them by 4 and multiply them by 3:

\dfrac{3}{4}(8x-4)=7x+2 \iff 3(2x-1)=7x+2 \iff 6x-3 = 7x+2

Subtract 6x from both sides:

-3=x+2

Subtract 2 to both sides:

x=-5
