Answer:
- t = -5/2
- -21
Step-by-step explanation:
3t - 7 = 5t
~Subtract 3t to both sides
-7 = 2t
~Divide 2 to both sides
-7/2 = t
~Find 6t with what we found for t
6(-7/2)
-21
Best of Luck!

Answer:
18
Step-by-step explanation:
Since you know the perimeters are equal, write your equation.
x+6 + x+6 + x+6 = x + x+6 + 2x-6
combine like terms
3x + 18 = 4x
isolate your x by subtracting 3x from each side
18 = x
check your answer:
3x + 18 = 72
4x = 72
Answer:
a. 4/7
e. 3/4
Step-by-step explanation:
For each part of the question, count the dots that meet the first requirement, and count the dots that meet the "fraction of ..." requirement. The desired fraction is the ratio of these numbers. In the answers above, we have reduced the fractions to lowest terms, but the question does not seem to require that.
__
a. The desired fraction is ...
(dots in the triangle)/(all dots) = 16/28 = 4/7
__
e. (dots in the rectangle not in the circle)/(dots in the rectangle) = 9/12 = 3/4
