25 PTS!!!!y = 3x + 3 y = x − 1 Explain how you will solve the pair of equations by substitution. Show all the steps and write the solution in (x, y) form

Answers

Answer 1

Answer: remember that you can do anything to an equaiton as long as you do it to both sides
ok so subsitution
basiclalyy you subsitute a known thing for an unknown thing so
y=3x+3 and y=x-1
they both equal y so
3x+3=y=x-1
3x+3=x-1
subtract x from both sides
2x+3=-1
subtract 3 from bot sides
2x=-4
divide both sides by 2
x=-2
subsitute
y=x-1
y=-2-1
y=-3

the solution is x=-2 y=-3 so
(x,y)
(-2,-3)

Which situation can be represented by the
inequality 4x − 25 < 125?

Answers

First add 25 to both sides of the inequality.
You get 4x < 150
Now divide both sides by 4.
You get x < 37.5
So x can be anything less than 37.5, such as 36, 35 or 34.

1) Mr. Adams had 24 guests at his house for a party. Each guest brought one item. - One-third of the guests brought drinks.

- One-fourth of the guests brought a dessert.

- The rest of the guests brought chips.

How many guests brought chips?

Answers

10 guests brought chips. To find the total number of guests who brought each item, all you need to do is divide 24 by the number in the fractions denominator. Then, add your answers and subtract them from 24 to get the total number of guests who brought chips.

24 / 3 = 8
8 guests brought drinks.

24 / 4 = 6
6 guests brought desserts.

6 + 8 = 14
24 - 14 = 10
10 guests brought chips.

Hope this helps!

Answer: The answer would be 10 guests brought chips
