I am pretty sure it is 3520 feet per minute.
Answer:
x=10
Step-by-step explanation:
3x+8x=100+10
11x=110
x=110/11
x=10
3/4 mile is 0.75 mile per minute
There are 60 minutes in one hour
0.75 times 60 equals 45 miles
Answer:
x ≤ 6
Step-by-step explanation:
5x - 9 ≤ 21
Step 1. Add 9 to both sides
5x ≤ 30
Step 2. Divide it all by 5
x ≤ 6
As far as the old dimensions of the photo are concerned,
Width of the photo = 3"
Length of the photo = 5"
New length of the photo = 7 inches
Let us assume the new width of the photo = x inches
Then
3/5 = x/7
5x = 7 * 3
5x = 21
x = 21/5
= 4.20 inches
So the correct option among all the options that are given in the question is the first option. I hope that the answer has come to your help.
