Answer:
The equation is true.
Step-by-step explanation:
Simplify. Combine like terms:
3x + 15 = (2x + x) + (10 + 5)
3x + 15 = (3x) + 15
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3x and 15 from both sides:
3x (-3x) + 15 (-15) = 3x (-3x) + 15 (-15)
3x - 3x = 15 - 15
0 = 0
~ True. The two expressions are equal to each other.

Answer:
149
Step-by-step explanation:
easy
8/32
16/64
32/128
If you simplify all of these (divide by the greatest common factor), you will get 1/4
175%
80*x=140
x=1.75 or 175%
like t.v. dont like t.v total
like reading 70 10 80
dont like reading 20 30 50
total 90 40 130
percentage of students like t,v and reading : 70/130 = 0.538 = 53.8%
probability of a student who does not like watching t.v. also does not like reading. : 30/40 which reduces to 3/4
