8p-7 is the eqation your using, -7 is spaces back (this is your numer for each of 8 turns) 8 times 7 eqalls 56 make this a negative, -56 spaces
Answer:
First Equation:
12x+7<−11
12x+7−7<−11−7
12x<−18
12x/12<-18/12
x<-3/2
Second Equation:
5x−8 ≥ 40
5x-8+8 ≥ 40+8
5x ≥ 48
5x/5 ≥ 48/5
x ≥ 48/5
Step-by-step explanation:
6.75+5.95=12.7
17.40-12.7=5
5÷2= 2.5
Each cost 2.5
Answer:
b = 180 - a - c
Step-by-step explanation:
To solve for <em>b</em> given the literal equation, a + b + c = 180:
Subtract a and c from both sides:
a + b + c = 180
a - a + b + c - c = 180 - a - c
b = 180 - a - c
