Answer:
p = 35
Step-by-step explanation:
( 2p + 5 ) + ( 3p ) = 180
-
2p+5+3p=180
Combine 2p and 3p to get 5p.
-
5p+5=180
Subtract 5 from both sides.
-
5p=180−5
Subtract 5 from 180 to get 175.
-
5p=175
Divide both sides by 5.
p = 175\5
Divide 175 by 5 to get 35.
-
p = 35
Solve for
m by simplifying both sides of the inequality, then isolating the variable.

The area of a square of side length B centimeters is
If we have two rows, each one containing B of those squares, then the total area is
Simplifying
Answer:
127 from 35
127 - 35
92
Step-by-step explanation:
So let's say
x=number of five dollare bills
y=number of 1 dolar bills
20 bills total
x+y=20
totla is 72 monies
72=5 times x+1 times y=5x+1y=5x+y
solve
x+y=20
5x+y=72
from here you could do 2 things: go to option 1 (longer) or option 2 (shorter)
1.
x+y=20
subtract x from both sides
y=20-x
5x+y=72
subtract 5x from boths ides
y=72-5x
subsitute
y=20-x=y=72-5x
20-x=72-5x
add 5x to both sides
20+4x=72
subtract 20 from both sides
4x=52
divide both sides by 4
x=13
subsitute
x+y=20
13+y=20
subtract 13
y=7
2.
another way is when you got 5x+y=72 and x+y=20
you negative the second equaiton and add to th efirst
I know it sounds like voodo at first but it works
-(x+y=20)=-x-y=-20
add
5x+y=72
<u>-x-y=-20 +</u>
4x+0y=52
4x=52
divide both sides by 4
x=13
subsitute
x+y=20
13+y=20
subtract 13
y=7
