Let:
x = Desired Number
The information put into numbers would look like this:
x - 5 = 3
All we have to do is add 5 to both sides to get x on its own on the left and a single number on the right side, so:
x = 3 + 5
x = 8
Total ratio = 4+7 = 11
33/11 = 3
4x3 = 12
7x3 = 21
so the two groups are 12:21
which is also = 4:7
Answer:
h = 9 cm.
Step-by-step explanation:
V = kBh where k is the constant of variation.
From the given info:
32 = k*16*6 = 96k
So k = 32/96 = 1/3.
So we have the equation of variation:
V = 1/3Bh
When V = 60 B = 20, so:
60 = 1/3 20h
20h = 60 * 3 = 180
h = 180 /20 = 9.
Hey
Width of the photo = 3"
Length of the photo = 5"
New length of the photo = 7 inches
Then
3/5 = x/7
5x = 7 * 3
5x = 21
x = 21/5
= 4.20 inches
