Answer:
B. 63
Step-by-step explanation:
There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.
Therefore:
(6 + 3)/3 = x/21
9/3 = x/21
3 = x/21
Cross multiply
21*3 = x
63 = x
x = 63
Answer: t-13 C
Step-by-step explanation:
If the regular price of a tent is 13 and Harold has a coupon for 13 off, this means Harold has been subsidized by a factor of 13. The amount Harold will pay will be 13 less than t which is t-13 i.e 13 subtracted from the total regular price.
Answer:
( - , - )
Step-by-step explanation:
Given the 2 equations
8x = 2y + 5 → (1)
3x = y + 7 → (2)
Rearrange (2) expressing y in terms of x by subtracting 7 from both sides.
y = 3x - 7 → (3)
Substitute y = 3x - 7 into (1)
8x = 2(3x - 7) + 5 ← distribute and simplify right side
8x = 6x - 14 + 5
8x = 6x - 9 ( subtract 6x from both sides )
2x = - 9 ( divide both sides by 2 )
x = -
Substitute this value into (3) for corresponding value of y
y = 3 × - - 7 = - - = -
Solution is (- , - )
So than you divide 5000 by 2 you will get (5/2) *1000 so 2,5 *1000 = 25*100 = 2500
