Answer:
theirs many 1, 3, 5, 7, or 9.
Step-by-step explanation:
Bring like terms together
(REMEMBER CHANGE THE SIGN WHEN MOVING ACROSS THE EQUAL SIGN i.e. - becomes + and + becomes -)
4x - 2x = 7 - 3
2x = 4
divide both sides by 2
x = 2
160 is the first because 1 inches 20 but it says 2 inches so at 40+40+40+40
and the 2nd part is yes he is correct because he converted the inches into feet so i think he is also correct
<span>The word decreased by means subtract.
So...
Lets look at A.
A: a-b
Sound correct?
No,
Because the sentence said that "a is decreased by the number b."
Lets look at B.
B. b-a
Sound correct?
Yes,
Because a is getting decreased by b.
Your answer is, B.
Hope this helps!(:
