Answer:
x=13
Step-by-step explanation:
Angle A and angle B are supplementary
Supplementary angles add to 180 degrees
<A + <B = 180
7x-18 + 8x+3 = 180
Combine like terms
15x -15 = 180
Add 15 to each side
15x-15 +15 = 180+15
15x = 195
Divide by 15
15x/15 =195/15
x =13
Answer: Yes
Step-by-step explanation:
10x - 5x = 5x
5x + 5 = 5x + 5
The answer to this problem would be A, $1.15. You get this answer by taking the total cost and dividing that by how many yards of fabric, for example let’s take the first one. $2.53 divided by 2.2 would be $1.15, same goes for the rest.
Answer:
C. 98.0%
Step-by-step explanation:
If t represents 35 days, then in order to find the daily decay rate we will have to input 1/35 as the value of t.
100(0.5)^
= 98.039
The daily decay rate is 98.0%
