Answer:
43
Step-by-step explanation:
90 is on a straight line with an interior angle of the triangle. So, they add to 180. 90+x=180
x=90
133 is also on a straight line. 180-133= 47
47+90=137
that leaves p as 180-137 or 43.
Answer:
60x + 42y
Step-by-step explanation:
6(10x + 7y)
Use distribute property and multiply 6 to everything inside the parenthesis:
6 x 10x = 60x
6 x 7y = 42y
SO, 60x + 42y is the correct answer
Answer: x+3
The original function tells us to subtract 3 from the input x.
The inverse function will do the exact opposite: it adds 3 to the input x.
Answer:
56 gallons
Step-by-step explanation:
When her gas tank is full, she has x gallons in the tank.
when she went to the gas station, she had (5/8) of x gallons of gas in her tank. she added 21 gallons into her tank, then she had x gallons in her tank.
(5/8)x + 21 = x
subtract x and 21 from both sides
(5/8)x - x = -21
factor out an x from the left side
x(5/8 - 1) = -21
simplify the parenthesis
x(-3/8) = -21
multiply both sides by -8/3
x= 56 gallons
