Answer: Sara multiplied by 3 when she should have multiplied by 8.
Step-by-step explanation:
21 : 7*8
7*8 = 56
21 : 56
The simplest form of this ratio is 3 : 8
Same as before
total=(2w+75)(2w+35)=4w²+220w+2625
pool=75 times 35=2625
minus pool from total
4w²+220w+2625-2625=4w²+220w
Well, one advantage simply is that its a loan. If its a loan, you can pay little by little until its paid off. Not sure if this helps, but I hope it does.
Answer:
84
Step-by-step explanation:
let a be the 1's digit and b the 10's digit, then
a = 2b ← twice the 10's digit, thus
sum = 2b + b = 12, that is
3b = 12 ( divide both sides by 3 )
b = 4
and a = 2b = 2 × 4 = 8
The 2 digit number is 84
