Answer:

graph two points at the coordinates (-6, 0) and the coordinates (-8, 3), and make a line through them.

Step-by-step explanation:

First simplify. 2x+3y= -18., -----------> 3y= -2x -18., ---------> y= -2/3x -6

To graph this you would first go to the coordinates (-6, 0) and put a point there. Next, you would go to the coordinates (-8, 3) and put a point there. Then make a line and you are done. That should be right.

Trying to understand long division formula. 5 divided by 285.I have it down to 28-25 and i have 035 but why is 35 subtracted by

Sergeeva-Olga [200]

Explanation:

At each step, the product of the quotient digit and the divisor is subtracted from the dividend. This gives you the new dividend.

When the quotient digit is 7, the product of 7 and 5 is subtracted from the dividend. The dividend at that point is 35, so you have 35 - 35 = 0. The 0 is the next dividend. Among other things, that tells you you're done. (Any additional quotient digits will be zero.)

There are 100 sheets of paper in the printer, and the number of sheets of paper, p, left after ,t, minutes of printing is given

zalisa [80]

P(t)=number of sheet of paper after t minutes.
p(t) will have to be equal to 0, wnen the printer use all 100 sheets of paper;
Therefore;
if p(t)=0
Then:

-8t+100=0

We solve this equation.
-8t+100=0
8t=100
t=100/8
t=12.5

Answer: the printer prints 100 sheets of paper in 12.5 minutes.

3. Siti and Mary shared $35 in the ratio 4:3.<br> How much money did Siti receive?

Mashcka [7]

Answer:

$20

Step-by-step explanation:

First we will change the ratio so that we are finding how much money Siti receives to the total amount of money.

$4:3 \rightarrow 4:(3+4)=4:7$

Now we can solve for how much money Siti receives using a proportion.

$\frac{4}{7} = \frac{\mbox{money Siti receives}}{35}$

We can see that the denominator increases 5 times, so the numerator must increase 5 times too. This means Siti receives $20.
