Answer:
u = 2.5
Step-by-step explanation:
Since you're working with only one variable, you just need to solve for u:
9(u -2) + 1.5u = 8.25
Multiply the parentheses by 9
9u - 18 +1.5u = 8.25
Add the similar values
10.5u = 8.25 + 18
Simplify
10.5u = 26.25
u = 26.25/10.5
u = 2.5
Hello :D
Answer:
A. 
Step-by-step explanation:
First, you add by 14 both sides of an equation.
-14-5y+14>-64+14
Then, simplify by equation.
-64+14=-50
-5y>-50
Multiply -1 both sides.
(-5y)(-1)<(-50)(-1)
5y<50
Divide by 5 both sides of an equation.
5y/5<50/5
Divide numbers from left to right.
50/5=10
y<10 is the correct answer.
Hope this helps you! :D
