blank 1: 75

question 4 (4 points)
solve the proportion.
$\frac{3}{6} = \frac{6}{x+2}$
x= __________
blank 1: 10

question 5

Explanation:

Step1: Cross-multiply to isolate y

$25 \times 15 = 5 \times y$

Step2: Calculate left-hand side

$375 = 5y$

Step3: Solve for y

$y = \frac{375}{5}$

Step4: Cross-multiply to isolate x

$3 \times (x+2) = 6 \times 6$

Step5: Simplify both sides

$3x + 6 = 36$

Step6: Isolate the term with x

$3x = 36 - 6$

Step7: Solve for x

$x = \frac{30}{3}$

Answer:

For Question 3: $y=75$
For Question 4: $x=10$
