Answer:
60 push-ups
Step-by-step explanation:
Set up a ratio to represent the problem:
Molly : Liza
10 : 15
40 : ?
How did we get from 10 to 40?
You multiply by 4. Therefore, multiply by 4 on both sides of the ratio.
10 : 15
x4 x4
40 : 60
So, Liza does 60 push-ups while Molly does 40.
Answer:
Inequality Form:
x
>
7
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
x can be anything bigger then 7 to make this true.
Answer:
x = 31
ROS = 62
Step-by-step explanation:
QOR + ROS = 90 degrees as indicated by the box
28+ 2x = 90
Subtract 28 from each side
2x = 90 -28
2x = 62
Divide by 2
2x/2 = 62/2
x = 31
ROS = 2x = 2*31 = 62
3)
Now, use Pythagoras theorem to find x
Similarly,
4)
Now, use Pythagoras theorem to find b
You can solve all of them in a similar way.
