Answer:

see explanation

Step-by-step explanation:

Expressing as equations

9x + 10y = 297 → (1) ← that is B

8x + 5y = 194 → (2) ← that is D

To solve the system of equations, multiply (2) by - 2

- 16x - 10y = - 388 → (3)

Add (1) and (3) term by term to eliminate the term in y

(9x - 16x) + (10y - 10y) = (297 - 388), that is

- 7x = - 91 ( divide both sides by - 7 )

x = 13

Substitute x = 13 into either of the 2 equations and solve for y

Using (1), then

(9 × 13) + 10y = 297

117 + 10y = 297 ( subtract 117 from both sides )

10y = 280 ( divide both sides by 10 )

y = 28

Cost of a small box of candy = $13

Cost of a large box of candy = $28

For every 4 feet of fencing, the cost is $36 <br> 2 4 7. 10<br> 8 36 81
stiv31 [10]
If your amount of fencing was 247.10 then you would divide that by 4 and multiply your result by 36 to find the amount of money needed to build a fence, your result is $2,196, now of course you have have more than 4 feet left but since the problem asks every 4 feet of fencing costs $36, I’m going to assume that if you have more than 4 but less than 8 you get that for free

Joan pays 456.25 monthly on her mortgage. If her annual insurance premium is 1,560 and her annual real estate tax is 1,890, what
defon
The combined payment is 743.75.

The annual amount of insurance is 1560.  Dividing this by 12 gives us the monthly amount paid:
1560/12 = 130.

The annual real estate taxes are 1890.  Dividing this by 12 gives us the monthly amount paid:
1890/12 = 157.50

We add these to the monthly mortgage payment to find the total amount:
456.25+130+157.50 = 743.75
