Answer:
2rs
Step-by-step explanation:
simplify- 2*7r^2s^2/7rs
r^2 divided by r^1=r^(2-1)=r^1=r
s^2 divided by s^1=s^(2-1)=s^1=s
canceling out 7 as it appears on both sides of the fraction line
Answer:
<em>15 people</em>
Step-by-step explanation:
since Raul and his friends each weigh 1/20 ton,
and the total weight reads 3/4 ton
The total number pf people on the scale will be:
<em>The total weight of Raul and his friends divided by their individual weight</em>
==> (3/4 ton) ÷ (1/20 ton)
= 3/4 X 20/1 = <em>15 people</em>
I would make a proportion out of this to help solve it because I find proportions a bit easier to solve, so the proportion would be: 110/100=880/x
You would just solve it for 800
I think it’s a 55% increase
Answer:
Average rate of car: x+3
Walking rate: x
The equation is
