a garage chaged Mr Tilton $48 in parts and $36/h in labor many hours did the garage spend on Mr tilton's carr if total bill was$156

Answers

156 = 36x + 48

108 = 36x

3 = x

They spent 3 hours on the car.

48 is a constant, so we take this out first
156 - 48 = 108

Since 36 is the variable, we can divide the above result to get the amount of hours.
108/36 = 3 hours

What are the first six terms of the sequence a1=0,an=an-1-8

Answers

Answer:

0, -8, -16, -24, -32, -40

Step-by-step explanation:

$a_1=0\n\na_n=a_(n-1)-8\n\n\text{Put n = 2, n = 3, n = 4, n = 5 and n = 6 to the expression:}\n\na_2=a_1-8\to a_2=0-8=-8\n\na_3=a_2-8\to a_3=-8-8=-16\n\na_4=a_3-8\to a_4=-16-8=-24\n\na_5=a_4-8\to a_5=-24-8=-32\n\na_6=a_5-8\to a_6=-32-8=-40$

Answer:

a1 =0

a2 = -8

a3 = -16

a4 = -24

a5 = -32

a6 = -40

Step-by-step explanation:

a1 =0

an = an-1 -8

We subtract 8 each time

a1 =0

a2 = 0-8 = -8

a3 = -8 -8 = -16

a4 = -16 -8 = -24

a5 = -24-8 = -32

a6 = -32-8 = -40

Which ratios form a proportion?A. 4/12, 6/8
B. 16/12, 3/4
C. 3/2, 15/14
D.10/16, 5/8

Answers

D. 10/16, 5/8 because 5x2=10 and 8x2=16

the equations are equal to each other so they form a porportion

To find proportions, you need to cross multiply for every option. so when you set up a proportion for any of those options, they will look like this.
