Is anyone good at elimination method? I will give 10 points to the person that answer the question. :)Jill wants to solve the following system using the elimination method:

y = x + 8
y = 3x − 11

What number should the equation y = x + 8 be multiplied by to eliminate x?

Answers

To eliminate x, the coefficients of x's in both equations should be opposite numbers. Since the coefficient of x in the second equation is 3, the coefficient in the first equation should be -3. So she should multiply the first equation by -3.

-3!
-3y=-3x-24
y=3x-11
-2y=-35
y=17.5

PLEASE HELP ME! How do you factor out the coefficient of a variable?? Example: 5c - 15

Answers

divide both by a number that can go into both terms so it will be 5 .
$(5c-15)/(5)$ which is 5(c-3)

$5c-15=\n5(c-3)$

Carl puts $1.10 in his penny bank every day in the month of July (31 days) his total saving was 55.00 at the end of June. What’s the best estimate for Carl’s savings at the end of July

Answers

He saves $1.10 everyday in July.

So he will have ($1.10 x 31) = $34.10 saved in July.

His total savings will be ($34.10 + 55)

Hence he will have a total of $89.10 at the end of July.

ANSWER:
He will have $89.10 at the end of July.

You will need to find how much he got on July so you will need to multiply 1.10 and 31.

1.10 time 31 is 34.1

Then subtract 55-34.1=20.9

Answer:20.9
