1,578 pillows. For this I just multiplied 789 by 2 and that’s the problem I got. I also double checked it by dividing 1,578 by 2 and this I got 789
Lets say a number is x
The sum of 5 and three times a number
The sum of 5 and 3 times x
The sum of 5 and 3x (sum means to add)
3x + 5
answer
Let
x--------> the number of quarts of paint needed for the outside
y--------> the number of quarts of paint needed for the inside
we know that
---------> equation
---------> equation
Substitute equation in equation
therefore
<u>the answer is</u>
of paint for the inside
(3x+1)(4x-1)
3x+4x=7x
1-1=0
So
(3x+1)(4x-1) = 7x
I hope this helped and was right, have a nice day
