Answer:
x=61.71428 or 61 5/7
Step-by-step explanation:
We can use a ratio to solve
7 pieces 12 pieces
----------------- = ---------------
36 seconds x seconds
Using cross products
7x = 36*12
7x = 432
Divide by 7
7x/7 = 432/7
61 5/7
x=61.71428
Step-by-step explanation:
They are parallel.
Parallel lines have the same slope.
for the line y = -2x + 1 the slope is -2 and when we put the line 2x + y = 5 in general equation it will be y = -2x + 5, and it's slope is also -2.
Therefore, the lines are parallel
With percentage in the question, you divide the miles they drove by the total miles in the trip (and of course multiply it by 100).
Joe:
![\frac{20}{65} =.3077](https://tex.z-dn.net/?f=%20%5Cfrac%7B20%7D%7B65%7D%20%3D.3077%20)
.3077 times 100= 31% (just rounded the percentage to the nearest whole number).
Adam:
![\frac{35}{65} =.5385](https://tex.z-dn.net/?f=%20%5Cfrac%7B35%7D%7B65%7D%20%3D.5385)
.5385 times 100= 54%
Laura:
![\frac{10}{65} =.1538](https://tex.z-dn.net/?f=%20%5Cfrac%7B10%7D%7B65%7D%20%3D.1538)
.1538 times 100= 15%
Tell me if this helps!!
It is substitution. Because you are substituting 3=y into x+5=3
Answer:
<h2>B] (-10, 0)</h2>
Step-by-step explanation:
The x-intercepts are where the graph crosses the x-axis.
