2x+3-5.32=68.82
2x= 71.14
x=35.57
each sneaker costs $35.57
Answer:
$91 is the answer.
Step-by-step explanation:
R = 6%
P = $70
T = 5 year
now
I = PTR/100
=(70×5×6)100
= 2100/100
= $21
So,
I = A-P
21 = A-70
21+70 = A
so, A = $91
Answer:
y - 1 = (1/3)(x + 2)
Step-by-step explanation:
Here m = 1/3 and (-2, 1) is a point on the line. The appropriate equation is
y - k = m(x - h), where (h, k) is the pt on the line.
Subbing the known values, we get:
y - 1 = (1/3)(x + 2)
Answer:
Step-by-step explanation:
1 In general, given a{x}^{2}+bx+cax

Answer: $2,446.08
Step-by-step explanation:
Lets convert the length and width into decimal form so it's easier to understand.
24 1/2= 24.5
12 4/5= 12.8
Now we must multiply to get the area. 24.5x12. 8= 313. 6 ft
Each square inch costs .65 so we must multiply .65 by 12 to see how much a foot costs. 12x0.65= 7.8
Now that we know how much each foot cost lets multiply 313.6 by 7.8. 313.6x 7.8= $2446.08
