Answer:
10
Step-by-step explanation:
The first equation should be the same with the second one, then we will have an infinite number of solutions of this system.
So if I multiply the first equation by 3, it'll be
6x-18y=3k
So if they should be the same, 30=3k
K=10
42 represents 35% of the total mulch he had on the truck.
Set up an equation.
42 = .35x
divide both sides by .35
x = 120 pounds
CHECK
120(.35) = 42 pounds
Answer:
x = 30
y = 14
Step-by-step explanation:
If the linear pairs are equal, then we can conclude that the angle on each of the sides is 90
Thus 3x = 90
and x = 90/3 = 30
Also;
9y - 36 = 90
9y = 90 + 36
9y = 126
y = 126/9
y = 14
