Answer:
x = 146
Step-by-step explanation:
The exterior angle of the triangle is equal to the sum of the opposite interior angles
x = 48+98
x = 146
Let x = Craig's time
Let y = Tom's time
Create a system of equations to solve this problem.
8 = x + y
y = 4x
Substitute 4x into the y variable in the first equation.
8 = x + 4x. Combine like terms
8 = 5x. Divide each side by 5.
1.6 = x
Craig takes 1.6 hours to clean the house
Division is multiplication by the reciprocal. The reciprocal is when you see what times your fraction equals 1.
Here's your answer. Just simplify now.
7/8 * 4/9= 28/72
Answer:
32
Step-by-step explanation:
2x+y=8 is the equation perpendicular to x-2y=8.
