Answer:
Step-by-step explanation:
42:7=ED:24
cross multiply 42 into 24.
Then divide by 7
you will get ED
Then use pythageorous theorem.
Ed square + 42 square=Ef square
Then do square root of Ef square
4(d-8)-5 = 9(d+2)+1
Assuming you're looking for d:
Use Distributive Property for both sides
4d-32-5 = 9d+18+1
Combine like terms
4d-37 = 9d+19
Take all d's to one side & numbers to other
-37-19 = 9d-4d
Simplify
-56 = 5d
Divide both sides by 5
d = -56/5
Answer:
14
Step-by-step explanation:
All you need to do is turn 70% into a decimal which is .70
Then multiply .70 and 20
.70*20
which gives you 14
6 is in the ten millions place. The number next to 6 is 1, which is less than 5, so you round down. The nearest 10 million is 60,000,000.
