Answer:
15
Step-by-step explanation:
32-19 = 13 that have both
70-57= 13 that have both again from that sample
total number of people that have both : 13 + 13 = 26
11 kids don't have either one, so :
26-11 = 15
Answer:
x = 20/32
Step-by-step explanation:
you have to distribute first.
1) times 4 by all the nubmers and figures inside the pharanthesese and so you get 32x + 20
2) you have to solve for x and so you move the 20 to the other side and get 32x = 20
3) you then divided both sides by 32 to get x by itself and you get x = 20/32
Given the quadratic equation:
Using the general solution for quadratic equations:
From the problem, we identify:
Then:
And the solution set is:
![\lbrack\frac{-5-3\sqrt{5}}{2},\frac{-5+3\sqrt{5}}{2}]](https://tex.z-dn.net/?f=%5Clbrack%5Cfrac%7B-5-3%5Csqrt%7B5%7D%7D%7B2%7D%2C%5Cfrac%7B-5%2B3%5Csqrt%7B5%7D%7D%7B2%7D%5D)
310 miles ÷ 5 hours = 62 miles per hour
403 miles ÷ 62 = 6.5 hours
The answer is -2-m- plz make brainliest
