Distribute proporty
a(b+c)=ab+ac
3=a
b=40
c=7
3(40+7)=3*40+3*7
I think it would take an average of both the numbers so first find the average of 60 and 90 by adding and dividing by two. You will get 75 seconds. That is the answer
Answer:
9.5 is the distance between the two points rounded to the nearest tenth.
6 pints = .75 gallon
4 cups = .25 gallon
so if you add .75 and .25, it should equal 1 gallon.
Answer:
or -116/9
Step-by-step explanation:
Use algebraic manipulation:
Note: Remember, anything you do to one side of the equation you also do to the other side (e.g. +5 on one side, +5 on the other side).
First, multiply the whole equation by -1 to get the x to be positive so you get:
9x + 13 = -103
then subtract 13 from both sides:
9x = -103 - 13
9x = -116
then divide by 9:
x = -116/9
