Question

2. Choose all of the equations that are

true if 3x = 5.
A 38.75-35.25 = x
B x+2=4
C ²x=2²/
D 9.7+x= 11
E9x=15

Answer 1

If 3x=5, then x=5/3 or 1.66
38.75-35.25=3.5, so it's not A.
4-2=2, so it's not B.
x^2 isn't 2^2 because x isn't 2, so it's not C.
11-9.7=1.3, so it's not D.
1.66x9 does equal 15, so the answer is E.
