Answer:
X = 10
Step-by-step explanation:
the triangles are similar meaning one is smaller we have all the sides on the smaller one
10 to 25 is a 2.5 increase
so 4 x 2.5 = 10
Answer:
1. 4x + 6
2. -15x + 11
5. -x + 4
6. -4x + 7
9. 5x - 2
12. x + 16
Step-by-step explanation:
Remove the parenthesis for each one so everything's out in the open. Next, you group like terms. The numbers with variables on one side, and the other numbers on the other side. For example:
x + 3x - 2 + 8
Then, you combine like terms:
4x + 6
That's mostly how you do each one.
One mile equals 5,280 feet, therefore you would multiply 12 x 5,280 which is 63360 feet per hour.
