50*x=80 (x=percent in decimal form)
x=1.6 (divide both sides by 50)
Doubke check:
50*1.6=80
80=80
Convert 1.6 into a percent:
1.6 -> 160%
Answer:
x = 63
Step-by-step explanation:
From the question, we can deduce the following points;
- 12 less than x which simply means 12 subtracted from x.
- the value of the above expression is equal to 51.
Translating the word problem into an algebraic expression, we have;
x - 12 = 51
Rearranging the equation (collecting like terms), we have;
x = 51 + 12
x = 63
Answer:
4
Step-by-step explanation:
12 minutes because it is three miles into for the train to go completely in and out (one mile for the nose to enter, on mile for the nose to exit and tail enter, and one mile for tail to exit). 3/15=x/60
Answer:
x = 6
Step-by-step explanation:
Line segment SU is a bisector of angle <TSV which means it divided the angle into two equal parts:
The measure of <TSV = 62 in this case the measure of <VSU = 62/2 = 31
we can write the following equation to find the value of x
5x + 1 = 31 subtract 1 from both sides
5x = 30 divide both sides by 5
x = 6
