Answer:

13

Step-by-step explanation:

a parallelogram has sides that are parallel to the opposite side. This means that y + 7 is going to be parallel to 20.

Two opposing sides of a parallelogram are parallel and equal

You know that the length of both of the sides is equivalent because the other set of opposing lines is also parallel (you can think of it as cutting off the line segment of y+7 and 20 at the same length. )

this means that we can set up the equation to find y as:

y + 7 = 20

then, you can proceed to find y by isolating it:

y + 7 = 20 ; so therefore

y + 7    =    20

   - 7           -7

y           =     13

y = 13

So, the value of y is 13

user100 [1]

Answer: The monthly payments for a $5,000 loan would $146.51.

Step-by-step explanation: How it looks in the TVM Solver formula:

N = 36 ( 3 (years) x 12 (monthly payments) )

I% = 3.5%

PV = $5,000

PMT = 146.51 (or 146.08 if you choose BEGIN)

FV = 0

P/Y = 12 (months)

C/Y = (12 (months)

PMT: <u>END</u> | BEGIN

HELP PLEASE
mel-nik [20]

Answer:

4 weekdays and 2 weekends.

Step-by-step explanation:

6 days.

x = weekdays

y = weekends

7x = amount with weekdays

12y = amount with weekends

7x + 12y = 52, total

x + y = 6, amount of days

solve double variable equation

x = 6 - y, plug in to 1st equation

7(6 - y) + 12y = 52

42 - 7y + 12y = 52

5y = 10

y = 2 weekends

2 + x = 6

x = 4 weekdays
