Answer:
The answer is 9.75
Step-by-step explanation:
6.25
4.50
Equals 9.75
You have to add a 0 after the 5 in 4.5 because the 5 is in the tenths place.
Sorry if it isn’t right, that’s how I was taught.

7.36/32=.23
23 percent
Step-by-step explanation:
the ratio of the pool lengths is 3/5.
that means for every 3 meters of length on Shantel's pool, there are 5 meters of length on Juan's pool.
it the other way around : to get to the size of Shantel's pool, every 5 meters of length on Juan's pool are converted to 3 meters.
x = length of Juan's pool
x × 3/5 = 30
3x = 150
x = 50 meters
you see the relationship ?
3/5 = 30/50 = 300/500 = ...
but it is true for any factor
3/5 = 15/25 = 24/40 = 6/10 = ...
once you see the factor for one part of the ratio, you know there is the same factor for the other part (or parts) of the ratio. otherwise the ratio would not stay the same and keep the relationship.

Step-by-step explanation:
» First factorise out x²:
» Then factorise the second bracket using quadratic knowledge:
» The second bracket can not be factorised further because its roots/zeros are not whole numbers
Answer:
Using definition of midpoint, Q is the mid point of PR.
Step-by-step explanation:
Given 2PQ=PR
And Q lies on the line PR (It should be given in the problem itself else we have to assume it to prove "Q is the midpoint of PR").
Then PR=PQ+QR using segment addition postulate.
Let us plugin PR in given equation.
2PQ=PQ+QR
Subtract PQ from both sides.
2PQ-PQ=PQ+QR-PQ
PQ=QR
Since Q lies on the line PR and PQ=QR, Q is the mid point of PR.
Hence proved.
