Answer:
x = -16
5x = -80
1. divide 5 on both sides.
2. x = -16
Answer:
116*
Step-by-step explanation:
36* + 28* = 64*
180* - 64* = 116*
X = 15
X + 90 = 7x
X = 7x - 90
X - 7x = -90
-6x = 90
Divide both sides by -6
X = 15
Answer:
7.28 m
Explanation:
Use the Pythagorean Theorem. The length of the ladder is the hypotenuse.
a^2 + b^2 = c^2
a = 2, b = 7, c = ?
Plug in the values into the equation.
2^2 + 7^2 = c^2
4 + 49 = c^2
Square root both sides to get c = 7.28
3 13/20 yards.
Make 1 1/4 to 1 5/20
make 2 2/5 to 2 8/20
Add them together and get the answer!
