Answer:
92.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 92.5

Answer: 
Step-by-step explanation:
You need to draw a Right triangle as the one attached, where "x" is the lenght of a ladder Andrew will need to reach the top and be out of the flower bed.
You must apply the Pythagorean Theorem. This is:

Where "a" is the hypotenuse and "b" and "c" are the legs of the Right triangle.
If you solve for "a", you get:

In this case, you can identify in the figure that:

Therefore, knowing those values, you can substitute them into
and then you must evaluate, in order to find the value of "x".
This is:

The answer would be negative 6 or -6.
