Answer: It may or may not be B.
Answer:there are 14 5point problems and 15 2point problems on the test.
Step-by-step explanation:
x represents number of 5 point questions and y represents questions worth 2 points.
The total number of questions in the test is 29. It means that
x + y = 29
x = 29 - y
Mr. Martin’s math test is worth 100 points. It means that
5x + 2y = 100 - - - - - - - - -1
Substituting x = 29 - y into equation 1, it becomes
5(29 - y) + 2y = 100
145 - 5y + 2y = 100
- 5y + 2y = 100 - 145
- 3y = - 45
y = - 45/-3
y = 15
x = 29 - y = 29 - 15
x = 14
Answer:
0.1
Step-by-step explanation:
-5|10x+9|+3=8
note: absolute value means positive
-5+10x+9+3=8
collect like terms
9+3-8-5=-10x
12-13=-10x
-1=-10x
x=-1/-10
x=1/10
x=0.1

Answer: 1 PM = $8
1:15 PM = $9.0
Step-by-step explanation:
a. Since Sadie rents a pair of skates at 10 A.M and returned the skates by 1 P.M, this means the hours spent was 3 hours. Therefore, based on the graph, for 3 hours rented, he will pay $8
The amount that she will pay if she returns them at 1:15 P.M. will be equal to the value of 3 hours 15 minutes which will be:
= $8 + $1.0
= $9.00
