Answer:
x=104°
Step-by-step explanation:
180=(x+4) +72
180-72=x+4
108=x+4
108-4=x
104=x
x=104°
Hope this helps! :)
Typically, you plot independent (x) vs dependent (y). Also, we list the variables on a table as x on top and y below. In this situation the miles travelled would be the variable the researcher controls (the independent variable) and number the of gallons used would be what was measured (the dependent variable). Answer J
P-1 = 5p+8p-8
p-1 = 13p-8 (collect like terms)
p+7 = 13p (add 8 to both sides)
7 = 12p (minus p from both sides)
7/12 = p (divide both sides by 12)
p = 7/12
Answer:
20.25 m²
Step-by-step explanation:
the area (A) and circumference (C) of a circle are calculated using the formulae
C = 2πr and A = πr² ( where r is the radius )
calculate the radius using the formula for circumference
2πr = 9π ( divide both sides by 2π )
r = 
= 
= 4.5, hence
A = π × 4.5² = 20.25π m²
You have to divide 600 dollars by 24 months which equals $25 so you have to pay $25 dollars every month for 2 years.
(if you want to check you can multiply 25x24)
The answer: $25
