X = the number of months the tire was used
y = the thickness of the tire tread
y = -(3/7)x + 20
Substitute x for 20 (the number of months the tire was used) and solve for y.
The next question: Substitute x for 49 (the number of months the tire was used) and solve for y.
Answer:
15 ft
Step-by-step explanation:
Hi, the illustration for the problem is a right triangle with:
hypotenuse (C)= the length of the ladder = L
horizontal side(A) = distance from bottom of the ladder to the building = L - 6
vertical side(B) = distance from the top of the ladder to the bottom of the building = L - 3
So, we can use Pythagoras formula:
A2 +B2= C2
(L – 6 )² + (L-3)² = L²
L²-12L+36+L²-6L+9 =L²
L2 -18L+45 =0
APPLYING QUADRATIC FORMULA WE OBTAIN:
L =15 OR L=3
If L=3
Vertical side = L-3 = 0 (Length can´t be 0)
So L=15

<span>Since Jeff is paying an annual amount of $744 he needs to set aside 12 monthly payments for the year. To figure out how much each payment would be you divide the total for the year 744 by the number of months 12. $744/12=$62 Each monthly payment would be $62</span>
Answer:
3 and 1/2 minus 2/3 minus 1/3 =
7/2 minus 2/3 minus 1/3 =
21/6 minus 4/6 minus 2/6 =
17/6 - 2/6 =
15/6 = 5/2 = 2 and 1/2
Optionally, you can think of it this way:
He used 2/3 yards for the pillow and 1/3 yard for the scarf.
So he used 1 yard
3 and 1/2 minus 1 = 2 and 1/2 = 5/2
