Answer: y= -6.45 and y=5-x

Step-by-step explanation:

Subtract 5.1 from both sides.

-2y= 18-5.1

Simplify 18- 5.1 to 12.9

-2y=12.9

Divide both sides by -2

y= - 12.9/2

Simplify 12.9/2 to 6.45

y=-6.45

Factor out the common term 3.

3(x+y)=15

Divide both sides by 3.

x+y =15/3

Simplify 15/3 to 5.

x+y = 5

Sub. x from both sides

y= 5-x

An ice cream shop owner wants to find out what new flavor of ice cream he should sell in his shop. Which method would be the BES
nordsb [41]
D would be the most logical answer that I see. A does not help with what he is trying to accomplish. B Is not the best option because you don't wanna go to other places and see what different flavors they have cause you wanna be different you wanna create competition. C, your asking a couple of people that come into the shop and that number would vary. I just think D is the most logical answer because at least your asking a handful of people.    <span />

Calculate the total to be repaid on a loan of $4600.00 for 18 months at a<br>rate of 5%.​
alekssr [168]

Answer:

$4945

Step-by-step explanation:

the interest on the loan can be found by using this formula:

I = P · r · t     P = principal, r = interest rate, t= time (in years)

I = 4600(.05)(1.5)

I = 345

Total Amount = Principal plus Interest

Total Amount = 4600 + 345 = $4945
