120
Step-by-step explanation:
6 girls can send 60 text messages in 30 minutes, so 60 minutes woudl equal 120
Answer:
one
Step-by-step explanation:
3x + 20 = 5x
20 = 5x - 3x
20 = 2x
x = 10
one solution
The fourth choice goes in the first box.
The second choices goes in the second box.
The fifth choice (the one on the bottom row) goes in the last box.
The fourth choice is 2/6. When reduced it equals 1/3.
The second choice is 3/6. When reduced it equals 1/2.
So when you add them, 2/6 + 3/6, you get 5/6.
For this case we must find the inverse of the following function:
We follow the steps below:
Replace f(x) with y:
We exchange the variables:
We solve for "y":
Multiply by -2 on both sides of the equation:
We raise both sides of the equation to the square to eliminate the radical:
We subtract 3 from both sides of the equation:
We change y by f ^ {- 1} (x):
