Answer:
y = 5
Step-by-step explanation:
The 3 interior angles of a triangle sum to 180°
Sum the 3 given angles and equate to 180
100 + 4y + 25 + 3y + 20 = 180 ← simplify left side
7y + 145 = 180 ( subtract 145 from both sides )
7y = 35 ( divide both sides by 7 )
y = 5
Answer:
h(x) = - 4x² + 5
Step-by-step explanation:
To find h(x) = g(2x² + 1), substitute x = 2x² + 1 into g(x)
h(x) = - 2(2x² + 1) + 7
= - 4x² - 2 + 7
= - 4x² + 5
Answer:
The Answer is to determine the amount of interest charged during a specific time frame
Step-by-step explanation:
-2xy+3x-2xy+3x
-2xy-2xy+3x+3x ( combine like terms)
-2xy-2xy=-4xy
3x+3x=6x
-4xy+6x
Answer: B. -4xy+6x
Lets use a rule of three simple with direct proportion to solve:
20 boxes -----> 15 min
100 boxes ----> x
x = (100)(15)/20
x = 75
therefore it takes 75 mins to stack 100 boxes
If we use fractions to solve:
15/20 = x/100
and solve for x.
20/15 = 100/y
solve for y
