So for eliminating, you only solve for one variable first.

I solved for y, so I multiplied by -4 to eliminate the x.

Then I got y= -1

I then substituted that to one of the equations to get x.

A bank loans a customer $95,000 for a period of 20 years. The simple interest rate of the loan is 6.5%. What is the amount of si
Ostrovityanka [42]

Answer:

b

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 6.5%/100 = 0.065 per year,

then, solving our equation

I = 95000 × 0.065 × 20 = 123500

I = $ 123,500.00

The simple interest accumulated

on a principal of $ 95,000.00

at a rate of 6.5% per year

for 20 years is $ 123,500.00.

Please someone help me with this question below i am really stuck.
o-na [289]

Answer:

  £59.25

Step-by-step explanation:

The tricky part here is finding the height of the trapezoid shape of the lawn. You will notice the difference in lengths of the parallel edges is 20-12 = 8 meters. This means you can use the Pythagorean theorem to find the missing height, as it is the second leg of a right triangle with one leg 8 and hypotenuse 17.

  h^2 = 17^2 -8^2 = 289 -64 = 225

  h = √225 = 15

So, the lawn's shape is a trapezoid with bases 20 and 12 and height 15. These can go into the area formula ...

  A = 1/2(b1 +b2)h

  A = 1/2(20 +12)(15) = 240 . . . . . . square meters

__

That area is 2.4 times 100 square meters. That means 2.4 cans of weedkiller are all that are needed. If we can only purchase whole cans, then we need to purchase 3 cans of weedkiller, for a cost of ...

  £19.75 × 3 = £59.25

The cost of the cans of weedkiller needed will be £59.25.
