3(y+4)-3=y+(y+5)
3y+9=2y+5
1y+9=5
1y=-4
y=-4

7/8 of an hour is 52.5 minutes. 3/10 of 52.5 minutes is 15.75 minutes. They spent 15.75 minutes warming up and cooling down.
Answer:
3.3m+1.4
Step-by-step explanation:
Multiply 5 and 0.9m
Multiply 5 and 0.5
5 times 0.9m is 4.5m
5 times 0.5 is 2.5
Multiply -3 and 0.4m
Multiply -3 and 0.7
-3 times 0.4m is -1.2m
-3 times -.7 is -2.1
4.5m+ 2.5 -1.2m-2.1
Which is 3.3m+1.4
Hope this helps!
Answer:
1 inch : 4 feet
we know this because if you divide 8 by two you get four if you divide 2 by two you get one
Step-by-step explanation:
When you are looking at a rhombus you know that it will be 4 congruent triangles when the diagonals are added in. So if you draw the rhombus each of the triangles will have one side that is 12 feet and another that is 9. You can now use Pythagorean’s theorem to find the length of a side. The length will be 15 feet.
