Answer & Step-by-step explanation:
Devin runs an average of 15 min in 7 days
15 * 7 = 105 minutes
She has a goal of running 10² min. in 7 days
10² = 100 minutes
Will she complete her running goal in 7 days?
Yes. On average, she will run 105 minutes in seven days which is more than her 100 minute goal.
Let s represent the short side of the triangle. The long sides of the triangle are each s+1, and the triangle's perimeter is
... s + (s+1) + (s+1) = 3s+2
The length of one side of the square is s-2, and its perimeter is 4 times that, 4(s-2) = 4s-8. The square and triangle have the same perimeter, so
... 3s+2 = 4s-8
... 10 = s . . . . . . . . add 8-3s to both sides
The length of the shorter side of the triange is 10 units.
Answer:
53
Step-by-step explanation:
72 = x + 3x - 4
72 = 4x - 4
72 + 4 = 4x - 4 + 4
76 = 4x
76/4 = 4x/4
x = 19
3(19) - 4 = 53
