Answer:
(1/2, 5)
Step-by-step explanation:
8x + 7y = 39
-2(4x - 14y = -68)
-8x + 28y = 136
8x + 7y = 39
add the two equations together
35y = 175
y = 5
8x + 7(5) = 39
8x = 4
x = 1/2

Answer:
a. t = I/<u>Pr</u>
b. The value of t in the table is <u>3</u> years
Step-by-step explanation:
Solve for t in the formula.
I = Pr
~Divide pr to both sides
I/Pr = t
Using the formula above, we can solve for t.
75/(500)(0.05) = t
75/25 = t
3 = t
Best of Luck!
Answer:
40.25 yds to the the nearest 100th
Step-by-step explanation:
The diagonal forms a right triangle with the length and width.
The diagonal is the hypotenuse
So, let d = the diagonal distance
=
= 324 + 1296
= 1620
d = = 40.25 yds to the the nearest 100th
Answer:
Step-by-step explanation:
Sale price = 950 pounds + vat
Vat = 20%
Value vat = 20/10 × 950 = 190 pounds.
Since the vat is calculated before a discount is applied, it means that the amount on which the discount was applied is
950 pounds
The value of the discount would be
12/100 × 950 = 114 pounds
The amount to be paid including vat is
(950 - 114) + 190 = 1026 pounds
