Well in the first equation m= -17
So you just have to substitute -17 in and see if it makes sense
like with the first equation -17 + 25 does equal 8 therefore x (in the second equation) = m (in the first)
Answer:
the 2:The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. 3

Each pizza costs $8 and the delivery fee is $3.
Answer:
The answer is 11a+3
Step-by-step explanation:
Simplify the terms.
8a+3+5a-2a
Combine like terms.
8a+5a-2a=11
11a+3
The angles of a quadrilateral add to 360, so we can solve for x by adding the 4 angle measures together and setting it equal to 360:
90 + 140 + (x - 10) + (x - 20) = 360
Combine like terms:
230 + 2x - 30 = 360
200 + 2x = 360
200 - (200) + 2x = 360 - (200)
2x = 160
Divide both sides by 2:
2x/(2) = 160/(2)
x = 80
