$20.25 because 8.50 and 8.50 equal 17 and then subtract 2.00 makes 15, and then add 5.25 and you end up with 20.25
Question 1. 5b + 2 = 17
Step 1. Subtract 2 from both sides of the equation.
5b+2-2=17-2
Step 2. Then simplify.
5b=15
Step 3. Finally divide by 5.
5b/5=15/5
Answer: b=3
Question 3.
Step 1. Subtract 9 from both sides.
9+4b-9=17-9
Step 2. And simplify.
4b=8
Step 3. Finally divide by 4.
4b/4=8/4
Answer: b=2
Hope this helps! :)
Answer:
The answer is A.
Step-by-step explanation:
A. 3*(-9)= -27, 4*(-9)= -36, -27-(-36)= 9
B. 3*(-27)= -81, 4*(-9)= -36, -81- (-36) = -45
C. 3*3= 9, 4*9= 36, 9-36= -27
D. 3*(-3)= -9, 4*(-6)= -24, -9-(-24)= 15
