Answer:
20
Step-by-step explanation:
The answer would be 20 due to the fact that it would have to be 50 divided by 2.5 to get the answer of how many steps and 50 divided by 2.5 would equal 20
.23(m)-12=35.
Think this is right. Haven't done these in a while
The equation would be x+3x(10+2x)=142
The sides are 22cm , 54cm and 66 cm.
