Answer:

x = 1 and y =5

Step-by-step explanation:

8x -2y= -2\\Divide by -2\\-4x+y = 1\\add 4x\\y= 1+4x\\

Substitute this value of y in the next equation.

9x+5(1+4x) = 34\\9x+5+20x=34\\29x+5=34\\29x=29\\x=1

Solve for y using x.

y=4x+1\\y=4(1)+1\\y=5

Point G is between points F and H. FH = 102, FG = 5x + 9, and HG = 9x − 5. Show your work.
Mamont248 [21]
Refer to the diagram shown below.

FH = FG + GH, therefore
(5x + 9) + (9x - 5) = 102
5x + 9 + 9x - 5 = 102
14x + 4 = 102
Subtract 4 from each side.
14x = 98
Divide each side by 14.
x = 7

FG = 5x + 9 = 5*7 + 9 = 35 + 9 = 44
HG = 9x - 5 = 9*7 - 5 = 63 - 5 = 58

Answers:
Part A)  x = 7
Part B) FG = 44
Part C) HG = 58

Plllllplzzzzzzzzzzzzzzzzzzzzzzzzzz
Natalija [7]

Hello there!

The answer would be C since we are looking to find how far she ran based on the amount of miles that has passed.

As stated above, 6 minutes. However to find out how far she runs we have to change the speed to miles per minute.

6 minutes per mile is equal to 1/6 of a mile per minute

Formula for Distance is speed x time

The distance is d, the time is t and the speed is 1/6.

Plug it in:

d = 1/6t

Lastly, multiply by 6 on both sides.

d x 6 = 1/6t x 6

1/6 x 6 = 1t

6d = 1t

Answer: t= 6d

A shipping container in the shape of a rectangular prism is 60 feet long, 45 1/2 feet wide, and 14 feet tall. What is the volume
Rufina [12.5K]
C. 38,200 ft^3

Why you ask? Good question, how you solve volume is l•w•h=v (length•width•height=volume) so it was 60•45.5•14=38,200

Hope this helps!

Tracy recieves payments of $X at the end of each year for n years. The present value of her annuity is 493. Gary receives paymen
vladimir1956 [14]

Answer:

v = 1/(1+i)

PV(T) = x(v + v^2 + ... + v^n) = x(1 - v^n)/i = 493

PV(G) = 3x[v + v^2 + ... + v^(2n)] = 3x[1 - v^(2n)]/i = 2748

PV(G)/PV(T) = 2748/493

{3x[1 - v^(2n)]/i}/{x(1 - v^n)/i} = 2748/493

3[1-v^(2n)]/(1-v^n) = 2748/493

Since v^(2n) = (v^n)^2 then 1 - v^(2n) = (1 - v^n)(1 + v^n)

3(1 + v^n) = 2748/493

1 + v^n = 2748/1479

v^n = 1269/1479 ~ 0.858
