Answer: -0.875 -0.75 -1.6 0.9 1.2 2.5
Step-by-step explanation:
6.7 x 1.9 = 12.73
Therefore 190% of 6.7 is 12.73.
Answer:
![x=4](https://tex.z-dn.net/?f=x%3D4)
Step-by-step explanation:
![4x+24=8x+2x](https://tex.z-dn.net/?f=4x%2B24%3D8x%2B2x)
We'll combine the
and the
on the right side.
![4x+24=10x](https://tex.z-dn.net/?f=4x%2B24%3D10x)
Now, we'll subtract
from both sides.
![24=6x](https://tex.z-dn.net/?f=24%3D6x)
Divide both sides by
.
![4=x](https://tex.z-dn.net/?f=4%3Dx)
Ta-da!
Answer:
15 Hours
Step-by-step explanation:
So you have one block, and your friend has two.
We know that you work for 3 hours, this means that your only block must represent 3 hours.
And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.
Then in total, he tutored for 3 hours + 3 hours = 6 hours.
Therefore, you still have only one block, but now your friend has 5.
Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:
5*3 hours = 15 hours
y = 2x - 5
To find the x and y intercepts, plug in 0 for y (solving for x intercept) and 0 for x (solving for y intercept) then solve for the remaining variable.
Let's solve for the x intercept first, so plug in 0 for y.
0 = 2x - 5
Add 5 to both sides.
5 = 2x
Divide both sides by 2.
x = 5/2
Now plug in 0 for x and solve for y.
y = -5
x intercept = 5/2, y intercept = -5
