Answer:
X= -4
Step-by-step explanation:
First you subtract both sides by 3. You will get:
5x=-20
then you divide both sides by 5
-20/5=-4 so
x=-4
Answer:
x
Step-by-step explanation:
3/4 times 3
3 times 3 =9
9/4
9 divided by 4 = 2.25
because you have to paint the whole wall you have to have 2.25 so you can't round down therefore you have to round up
so the answer would be
3 gallons
Answer:
The SI metric system
Step-by-step explanation:
Answer:
z = 33/5 or 6.6
x = 5/2 or 2.5
Step-by-step explanation:
20 = 5z - 13
Add 13 to both sides.
5z = 33
Divide both sides by 5.
z = 33/5 or 6.6
-9 + 2x = -4
Add 9 to both sides.
2x = 5
Divide both sides by 2.
x = 5/2 or 2.5
