(1.) 35-3m
m= 4
35-3m
= 35-3(4)
= 35-12 (do the multiple/division first before doing the addition/subtraction)
= 23
C. 23
(2.) 1 + x ÷ 5
x = 80
1 + x ÷ 5
= 1+80÷5
= 1+16
= 17
(3.) mx-y
m=5, x=3, and y=8
mx-y
= 5(3)-8
= 15-8
= 7
(4.) 3a+15+bc−6
a=7, b=3, and c=15
3a+15+bc-6
= 3(7)+15+3(15)-6
= 21+15+45-6
= 75
Answer:
18 machines
Step-by-step explanation:
9 machines give 24 mins... You need to reduce the time by half by adding using double the machines..
So 9×2=18
True.
The vectors are -25 in the left direction and;
-52 in the left direction
So they lie on the same line.
Answer:
k = 54
Step-by-step explanation:
1. Multiply 6 time 9. This is the only step to get the answer.
6 × 9 = 54
k = 54
2. (Option step) To check your answer plug in 54 for k in the equation and divide it by 9. Your result should be 6.
54 ÷ 9 = 6
