Answer: 1X52=73
Step-by-step explanation:
Write equations for both companies:
Company A = 80 + 0.30x
Company B = 20 + 0.50x
X = number of miles.
Set the equations to equal and solve for x:
80 + 0.30x = 20 + 0.50x
Subtract 0.30x from both sides:
80 = 20 + 0.20x
Subtract 20 from both sides:
60 = 0.20x
Divide both sides by 0.20:
x = 60 / 0.20
x = 300
The answer is 300 miles.
Answer:
x = 1
y = -1
Step-by-step explanation:
A*B= (4y-8 3x-3)
1-) (4×2)+(3×y)= 3y+8
2-) (4×x)+(3×(-1))= 4x-3
AB=C
(3y+8 4x-3)=(5 1)
So
3y+8=5 ; y= -3/3 = -1
4x-3=1 ; x=4/4 =1
Answer:
13
Step-by-step explanation:
5 12 and 13 are a known triangle proportion relation.
also, 5 squared plus 12 squared is 169.
13 squared is 169.
(I just used the Pythagorean formula)
Step-by-step explanation:
am-an+bm-bn
m(a+b)-n(a+b)
(m-n)(a-b)
