The answer for your answer is (x+3)(2x+7)
Answer:
25%
Step-by-step explanation:
There are 20 minutes between 10 and 30 and 5 minutes between 10 and 15 so you need to find 5% of 20 (5/20 x 100) which is 25%
12.5 * .25=3 1/8 miles running part
3.125 * .5=1 9/16 miles kayaking part
12.5+3.125+1.5625=17 3/16 miles total race
Answer:
2/7(x-2)=4x
(2×x-2×2)/7 = 4x
(2x-4)/7 = 4x
2x-4×(1) = 4x × 7 ( Cross multiply)
2x-4 = 28
2x = 32
2x÷2 = 32÷2
x=16
