16
2.43
question 2 (2.5 points)
solve for x:
x/14 = 3/7

Explanation:

Question 1

Step1: Cross - multiply the proportion

Given the equation $\frac{1.3}{16}=\frac{y}{30}$, cross - multiplying gives us $16\times y = 1.3\times30$.

Step2: Calculate the right - hand side

First, calculate $1.3\times30 = 39$. So the equation becomes $16y=39$.

Step3: Solve for y

To solve for $y$, divide both sides of the equation by 16: $y=\frac{39}{16}=2.4375\approx2.43$ (rounded to two decimal places).

Step1: Cross - multiply the proportion

Given the equation $\frac{x}{14}=\frac{3}{7}$, cross - multiplying gives us $7\times x = 3\times14$.

Step2: Calculate the right - hand side

Calculate $3\times14 = 42$. So the equation becomes $7x = 42$.

Step3: Solve for x

Divide both sides of the equation by 7: $x=\frac{42}{7}=6$.

Answer:

2.43
