Answer:
Step-by-step explanation:
1. 8 seconds
2. 15 quarts
4+4x=20
-4. -4
4x=16
X=4 (hope this helps)
<span>Simplifying
4x + 5y = 11
Solving
4x + 5y = 11
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5y' to each side of the equation.
4x + 5y + -5y = 11 + -5y
Combine like terms: 5y + -5y = 0
4x + 0 = 11 + -5y
4x = 11 + -5y
Divide each side by '4'.
x = 2.75 + -1.25y
Simplifying
x = 2.75 + -1.25y</span>
Answer:
Step-by-step explanation:
10/7 x 9/8 = 90/56 = 45/28.
7/9 x 8/10 = 56/90 = 28/45
If you want to multiply these, the answer is (28*45) / 28/45) = 1.
The measure of an angle = 2 * the compliment of the angle - 15
Angle = 2 * (180 - angle) - 15
x = 2 * 180 - 2 * x - 15
x = 345 - 2x
3x = 345
x = 115 degrees.
