He got 22/25 questions right because
if you put X as the number of questions he got right out of 25 and equal it to 88 out of 100 you can cross multiply to get X
x/25=88/100
100x=25×88
25×88=2200
100x=2200
divide 100 on both sides
therefore
2200/100= 22
hope this helps
Answer:

The answer is most likely C. Cubic meters.
Answer:

Step-by-step explanation:
hello,
let's note a the number of novelists and
b the number of poets.
we know that a = 5/3 b as "enrolls novelits and poets in a ratio of 5:3"
it comes 3a=5b which is the first equation
and we know that a + b = 24 "there are 24 people"
we we have two equations
(1) 3a - 5b = 0
(2) a + b = 24
let's multiply (2) by 3 it comes 3a + 3b = 24*3 = 72
let's do 3*(2) - (1) it comes
3a + 3b -3a + 5b = 72 - 0 = 72
so 8b = 72
so b = 9
and then we replace b in (2) it comes
a = 24-9 = 15

Answer:
x = 4
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 8 when x = 10
k = yx = 8 × 10 = 80
y =
← equation of variation
When y = 4, then
4 =
( multiply both sides by x )
4x = 80 ( divide both sides by 4 )
x = 20
