Answer:
Eudora ran for 30 minutes and use the jetpack for 1 hour and 30 minutes
Step-by-step explanation:
Lets call x the time she ran and y the time she was using a jetpack (in hours), we have
12x + 76y = 120
Since it took 2 hours we have that x+y = 2, hence y = 2-x. We can replace y in the equation above, obtaining
12x + 76(2-x) = 120
12x+ 152 - 76x = 120
12x-76x = 120-152
-64x = -32
x = -32/-64 = 1/2 (30 minutes)
As a result
y = 1-1/2 = 3/2 (1 hour, 30 minutes)
She ran for 30 minutes and use the jetpack for 1 hour and 30 minutes.
Answer:
The answer to your question is No
Step-by-step explanation:
To answer this question use the Vertical line test. This test states that if we draw a vertical line and intercepts the function only in one point it is a function.
It the vertical line intersects the graph in two or more points, it is not a function.
See the picture below
The graph given is not a function because the vertical line crosses the graph in three points.
Answer: X=13/3
Step-by-step explanation:
1. Multiply Both sides by 12
8x-10=5x+3
2. Collect the like terms, calculate the sum
8x-5x=3+10
3.Divide both sides by 3
3x=13
Answer X=13/3
Alternative Form,
X= 4 1/3, X=4.3
Answer: <em>54 inches</em>
Step-by-step explanation:
<em>Let's take the equation for the area of a right triangle</em>
