Step-by-step explanation:
2(2+20)=80
4+40=80 (Distribute)
4+40-40=80-40(Subtract from both sides of the equation)
4=40(Simplify)
4/4=404/4(Divide both sides of the equation by the same term to get x=10)
=10
Answer:
x = 5
Step-by-step explanation:
Step 1: Subtract 2x from both sides.
4x−3−2x=2x+7−2x
<u>2x−3=7</u>
Step 2: Add 3 to both sides.
2x−3+3=7+3
<u>2x=10 </u>
Step 3: Divide both sides by 2.
2x/2 = 10/2
x=5
Answer:
23
Step-by-step explanation:
Ā means the average
So it means the average of 64 gave their speech which should be 64/2 = 32
So 32 gave their speeches yesterday,
7 gave today
Total number that has given is
32 + 7 = 39
Therefore the number remaining are
62 - 39 = 23
Answer:
The GCF for the variable part is ab².
GCF<em>Variable</em>=ab²
Multiply the GCF of the numerical part 5 and the GCF of the variable part ab².
5ab²
