Answer:
x = 58
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
90 = 32+x
Subtract 32 from each side
90-32 = x
58 =x
If your question is will he have enough money, the answer is no he will not.
X^2 - 13 x = -36
add 36 to both sides
x^2 - 13x +36 = 0
figure out the factor
(x-4)(x-9) = 0
so (x-4) or (x-9) equals 0
so solution is
x-4=0 add 4 to both sides and get x = 4
x-9=0 add 9 to both sides and get x=9
x={ 4, 9}
Solve for x by simplifying both sides of the inequality, then isolating the variable.
Inequality Form:
x<82
X-the $5 bills
y-the $10 bills
x+y=20
5x+10y=120
It's a system.
