84
Step-by-step explanation:
68 + 100 = 168
168/2 = 84
90÷5=18 which means she makes $18 every hour.
Answer= $18
First equation:
5(x+1)=20 —— distribute the 5 to the x and 1
5x+5=20 ——- subtract 5 from 20
5x=15 ———— divide by 5 from both sides
X=3 ————— answer
Second equation:
5x+1=20——— subtract 1 from 20
5x=19 ———— divide by 5 from both sides
X=19/5———— answer in fraction form
X=3.8————- answer in decimal form
Plus 16 on both side and negative 12plus 16 is 4 so x equals 4
Yes they can just think of numbers with opposite signs
I-5I=I+5I the absoulte value is 5
