Answer:
C) (6,2)
Step-by-step explanation:
Rewrite equations:
y=x−4;x+2y=10
Step: Solve y=x−4for y:
y=x−4
Step: Substitute x − 4 for y in x+2y=10:
x+2y=10
x+2(x−4)=10
3x−8=10(Simplify both sides of the equation)
3x−8+8=10+8(Add 8 to both sides)
3x=18
3x
3
=
18
3
(Divide both sides by 3)
x=6
Step: Substitute6forxiny=x−4:
y=x−4
y=6−4
y=2(Simplify both sides of the equation)
Hope this helps!

Answer:
$81,000
Step-by-step explanation:
A = Final Payment = ?
P = Principal Amount = $30,000
r = Interest Rate = 8.5%
t = Time = 20 Years
A = P(1 + rt)
A = 30,000(1 + 0.085 x 20)
A = 30,000 + 51000
A = $81,000
Hence, Steph will pay $81,000 altogether.
Answer:
24 hours
Step-by-step explanation:
set up a ratio:
12 miles = 16 hours
------------- ------------
18 miles = x hours
cross multiply
12m * x = 16h * 18 m
solve for x
x=16h * 18m / 12m = 24 hours
( divisor / dividend ) does not go into the same Evenly
