Answer:

Step-by-step explanation:

Set up a proportion.

3/25 = x / 20 Notice that both times are in the denominators. Be sure you always set up a proportion that way. Like units in the denominator. Like units in the numerator.

Cross multiply

3 * 20 = 25 * x Combine

60 = 25x Divide by 25

60/25 = x

x = 2.4 miles in 20 minutes.

Answer:

In 20 minutes, Trey would run 2.4 miles.

Step-by-step explanation:

20x = 25

x = 4/5

This means we multiply the number by 0.8

3 * 0.8 =

3/25 = 2.4/20

2.4 miles / 20 minutes

Answer:

x = 7

Step-by-step explanation:

$\frac{3}{7} x + 5 = 8$

$\frac{3}{7} x = 8-5$

$\frac{3}{7} x = 3$

$x = 3 / \frac{3}{7}$

$x = 3 * \frac{7}{3}$ cancel 3

Then

$x = 7$

Kellogg's produced 715000 boxes of cornflakes this year. This was 110% of annual production last year. What was last year's annu

Charra [1.4K]

Let last year product be x boxes.

110% of x means $\displaystyle{ \frac{110}{100}\cdot x$ .

Thus, we solve the equation:

$\displaystyle{ \frac{110}{100}\cdot x=715,000$ .

Multiplying both sides by $\displaystyle{ \frac{100}{110}$ , we have:

$\displaystyle{ x=715,000 \cdot \frac{100}{110}=650,000$ .

Answer: Last year's annual production was 650,000 boxes.
