Answer:
35 percent
Step-by-step explanation:
To solve this problem we multiply the amount by the percent and add them up to get the total amount times the percent
amount * percent + amount * percent = total amount * percent
4 * .20 + 12 * .40 = (4+12) * x
.8 + 4.8 = 16 x
Combine like terms
5.6 = 16x
Divide by 16
5.6/16 = 16x/16
.35 =x
35 percent
Answer:
r <= 12.6
Step-by-step explanation:
Let's calculate the rate at which he descends:

Answer:
Is there supposed to be a graph somewhere?
Answer:
19.1
Step-by-step explanation:
27 is half of 54, so that means that the second triangle is 1/2 the size of the first, meaning all sides need to be divided by 2 in order to get the answers for each side
Answer:
y = (1/6)x - 5
Step-by-step explanation:
Substituting m for the the slope:
y = (1/6)x + b
Plugging in the values showed in the point (x = 12, y = -3):
-3 = (1/6)12 + b
-3 = 2 + b
b = -5
y = (1/6)x - 5
Hope this helps!
