Answer:
x = -24
Step-by-step explanation:
We gotta get rid of that 3 under x, so we multiply the reciprocal of 1/3, which is 3, if we multiply that on one side, we must also multiply on the other side.
3 · x/3 = -8 · 3
x = -24
Hope this helps! good luck on whatever you're doing :]
Answer:
x = 25
Step-by-step explanation:
We know that the remaining angles add up to 90°, because the right angle (triangles have 180° total.)
2x + 15 + x = 90 | Given
3x + 15 = 90 | Combine x
3x = 75 | Subtract 15
x = 25
F(x) = 4 x 7x
f(x) = 4 x 7(-1)
f(x) = 4 x (-7)
f(x) = -28
(-1, -28)
f(x) = 4 x 7(2)
f(x) = 4 x 14
f(x) = 56
(2, 56)
Hope this helps!!

Hello! To find the unit rate in miles per gallon, all you have to do is divide the amount of miles by the amount of gallons. 2½ is 2.5 in decimal form. 50/2.5 is 20. There. The unit rate is 20 miles per gallon.
Answer:
When finding these problems we always have to do the opposite of the operation shown.
In this case its:
5x + 15 = 45
Subtract 15 from both sides (we start off with constants and numbers that are being shown) The reason why its subtraction is because since your adding 15 to 5x the opposite of that is subtraction so use the number shown by itself and subtract it from both sides.
5x = 30
Divide by 5 on both sides since the opposite of 5x is division (only use the number that is shown) We have to get rid of all the numbers on the left.
therefore you'll be left with:
X = 6
