Which of the following ratios is equivalent to 2:3? 12:13

14:21

20:25

1:4

14:21

Step-by-step explanation:

Think of it as equal fractions, if that helps.

Finding an equivalent fraction is the same as finding an equivalent ratio.

If you multiply both the numerator and denominator of 2/3 or 2:3 by the same number, you'd get an equivalent fraction/ratio.

2 multiplied by 7 is 14, 3 multiplied by 7 is 21. So, 2:3 and 14:21 are equivalent.

answer: i think it is (1,-2)

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
