(3x + 2y = 6
(13x + 2y = 3
b.
(6x+2y = 8
(3x - y = -2
Answer:
A. x = -3/10 , y = 69/20
B. x = 1/2 , y = 5/2
Step-by-step explanation:
A]
3x + 2y = 6......eq1
13x + 2y = 3.......eq2
From eq 2 - eq 1
10x = -3
x = -3/10
So,
3x + 2y = 6
3(-3/10) + 2y = 6
y = 69/20
B]
6x+2y = 8.....eq1
3x - y = -2.....eq2
eq2 x 2 and add in 1
12x = 6
x = 1/2
So,
6x+2y = 8
y = 5/2
Sam went to play video games in Video Game Central arcade. Video Game Central
charges $10 to get into the arcade and then $1 per game played. Represent the
relationship between total cost, y, and number of games played, x using a table, graph and
equation. Is this relationship a proportional or additive relationship? Explain.
Answer:
additive relationship
Step-by-step explanation:
Since y or $10 is only the amount to get in, you will only need to pay $10 once.
BUT, you need to play $1 PER game. For every game you play, you add 1 dollar.

Pedro made a pot of coffee for some friends. he served 34 ounces to his friends and then measured that there were 20 ounces leftover. How much coffee did Pedro make?
Answer:
Pedro made 54 ounces of coffee in total.
Step-by-step explanation:
Identify what you know:
1) Pedro gave his friend 34 ounces of coffee.
2) There was 20 ounces of coffee left over after!
So, we need to add the amount of coffee that his friend had, to the amount that's left, to get the total amount that he made.
Let's make an equation, where x equals the total amount!
34 + 20 = x
OR
x - 34 - 20 = 0
Hope this helps!
Answer:
54
Step-by-step explanation:
34+20= 54 ounces of coffee

1/8 miles per hour
8 hours per mile
8 miles per hour
1/8 hours per mile
Answer:
C. 8 miles per hour
Step-by-step explanation:
1/24th of an hour is 2.5 minutes, taking Diego 2.5 minutes to ride 1/3rd of a mile
2.5 x 3 (to signify how long it would take Diego to ride a mile) = 7.5 minutes
60 divided by 7.5 = 8
Therefore, Diego's speed in MPH is 8.

1/169=1/3 what's the exponent? how do i figure it out?
Answer:
Step-by-step explanation:
We have been given an equation . We are asked to write the missing exponent for our given equation.
We can see that 169 is square of 13, so we can write left side of our equation as:
We can raise 1 to any power and answer will be same.
Raising 1 to 2nd power, we will get:
Since both numerator and denominator is raised to 2nd power, so we can raise to 2nd power as:
Therefore, our missing exponent is 2.
can these side lengths form a triangle?

The degrees of rotation that will carry the regular pentagon onto itself is 72,144,216,288
What is a pentagon in geometry?In geometry, a pentagon is any five-sided polygon or 5-gon. The sum of the internal angles in a simple pentagon is 540°.
Given here: A regular pentagon is rotated clockwise about center P.
Now Since you have 5 vertices, your starting vertex can land in 5 different starting places and still come up with the same figure. So if you take 360/5 you get 72 degree rotations to each consecutive vertex.
or more specifically 360/5=72
Again therefore the pentagon will coincide itself after every integral multiple of 72
Thus 72, 144,216,288 are the required angles of rotation.

Step-by-step explanation:
We first have to get everything out of the parentheses, so we take the negative that is surrounding the parentheses and apply it to the equation inside of it, giving us this: 5g - 2h - 3h - 8 + 4g
Then, all we need to do is simplify it into this expression: 9g -5h - 8

A dilation has center (0,0). Find the image of the point B ( 5/3, -7/2) for the scale factor 1/3
=======================================================
Explanation:
Since the center of dilation is (0,0), we multiply each coordinate of point B by the scale factor 1/3.
The coordinates of point B are x = 5/3 and y = -7/2
So we have
(1/3)*x = (1/3)*(5/3) = (1*5)/(3*3) = 5/9 as the new x coordinate
and
(1/3)*y = (1/3)*(-7/2) = (1*(-7))/(3*2) = -7/6 as the new y coordinate
The point (5/3, -7/2) moves to (5/9, -7/6)
