I need help on 11-16

alisha [4.7K]

I cant see all of 11 and 14
12:
$3f = 18 \\ \frac{3f}{3} = \frac{18}{3} \\ f = 6$
13:
$3f = {3}^{2} \\ 3f = 9 \\ \frac{3f}{3} = \frac{9}{3} \\ f = 3$
15:
$3h = 9 + 10 \\ 3h = 19 \\ \frac{3h}{3} = \frac{19}{3} \\ h = 6.3$
16:
$3f = 27 - 21 \\ 3f = 6 \\ \frac{3f}{3} = \frac{6}{3} \\ f = 2$

Juan ran of a mile 2/5 every 4/7 of an hour. Find Juan’s rate in miles per hour

AfilCa [17]

Answer:

Juan runs 7/10 of a mile every hour

Step-by-step explanation:

First find out how much he ran every 1/7 of an hour

2/5 x 1/4 = 4/7 x 1/4

1/10 = 1/7

1/10 x 7 = 1/7 x 7

7/10 = 1
