Need help with problem can you help 5x+3y=22 y=2x

Answers

Answer 1

Answer: if y = 2x, let's replace it on $5x+3y=22$

$5x+3*(2x)=22$

$5x+6x=22$

$11x=22$

$\boxed{\boxed{x=2}}$

Therefore

$y=2x$

$y=2*2$

$\boxed{\boxed{y=4}}$

Answer 2

Answer: 5x+3y=22 y=2x
5x+3(2x)=22
5x+6x=22
11x=22
x=2

y=2(2)
y=4
x=2 y=4

Fathi wants to print out a PDF document that is 48484848 pages long. To save paper, he decides to print on both sides of each sheet and to print two pages on each side of the sheet. How many sheets of paper will he need?

Answers

Yes, as potatoelord said, divide 48,484,848 and 2.
48, 484, 848 ÷ 2 = 24, 242, 424.
This is because Fathi is using one paper for two pages.
Therefore, that is why you divide 48, 484, 848 and 2.

The data represent the number of phone calls received over a 70day period.Day 1 2 3 4 5 6 7
Calls Received 5 2 9 8 3 1 0

What is the mean number of phone calls received?

Answers

Are you talking about 7-day period instead? Or is that really 70?

Anyway, the mean number of phone calls received over the period of time given would be 4 calls. I got to this answer through adding all of the calls and dividing them by the number of days.

Mrs. Bergstedt teaches six classes. In her first period class she has 19 students, her third period she has 13 students, her fourth period 19 students, her fifth period 9 students, her sixth period 14 students, and her seventh period 15 students. What is her average class size, to the nearest tenth

Answers

19 + 13 + 19 + 9 + 14 + 15

19 + 13 = 32
32 + 19 = 51
51 + 9 = 60
60 + 14 = 74
74 + 15 = 89

89 / 6 (the number of classes she has)
= 14.8

Brenda observes that the keyboard and the screen of an open laptop lie on two different planes. In how many lines do the planes containing the keyboard and the screen intersect?

Answers

Let's assume the laptop is opened at 90 degrees (this is done for the sake of simplicity, is actually irrelevant) then each plane would be analogous to the 'x' and 'y' planes you see in a Cartesian Plane, which only intersect at one point called the Origin. Any two lines with different slopes will intersect only one time (if they're parallel they have the same slope)
