Answer: x=13
Explanation:
step 1 - multiply both sides by 6 to get rid of it
step 2 - simplify both sides
step 3 - subtract 1.4 from both sides
x = 13
Answer:
16
Step-by-step explanation:
20^2 - 12^2 =
400-144 =
256 = 16^2
use formula a^{2}+b^{2}=c^{2}
Solution:
<u>Note that:</u>
<u>Using cross multiplication:</u>
- (3x)/20 = (4x + 2)/28
- => (3x) × 28 = (4x + 2) × 20
<u>Simplifying both sides:</u>
<u>Subtracting 80x both sides:</u>
- 84x = 80x + 40
- => 84x - 80x = 80x + 40 - 80x
<u>Simplify the LHS:</u>
- => 84x - 80x = 40
- => 4x = 40
- => x = 10
2 miles per hour
all you have to do is multiply 1/3 by 6 since she only walks 1/3 miles in 1/6 of an hour and you want to find the miles walked in a hour<span />
