You have to do whats in the parentheses from left to right then subtract the answer you get by 20
(9x10) - (30+30)
90 - 60 = 30
8 x (12+5) -7^2
17
17-49
18 x -32
= -576.
You have to use pemdas for your check off
P=parentheses
E=exponet
M=multiplication
D=division
A=add
S=subtrabt

Answer:
70%
Step-by-step explanation:
60 - Altogether
18 - Strawberries
42 - Lemons
42/60 = 0.7
0.7 x 100 = 70%
First one:
3x+5<23
3x<18 (subtract 5 from both sides)
x<6
So A: less than 6 cars
Second one:
3(x-4)+5(2x+1)
3x-12+10x+5 (distribute)
So the answer is C
