10 = 3x - 2
Add 2 for both sides
3x = 12
X = 4
then adding 2 to both sides gives 3x=12. dividing both sides by 3 returns x=4.

During a football game, the parents of the players are selling pretzels and popcorn to make money. They charge $2.50 for a bag of popcorn and $2 for a pretzel. The parents collect $336 in sales. They sell twice as many bags of popcorn as pretzels.
Write a system of equations to represent the situation.
How many pretzels did they sell?
Answers
Answer:
The parents sell 48 pretzels.
Step-by-step explanation:
Let a be the number of bags of popcorn sold, and b the number of pretzels sold.
2.5a + 2b = 336
a = 2b
2.5a + a = 336
3.5a = 336
a = 96
b = 48

Your job is to sort and stack marblesfor sale. A bag contains 44 marbles, and some green. If there are 11 red marbles, what is the ratio of green to red marbles
Answers
Answer:
3 : 1
Step-by-step explanation:
Given that :
Total Marbles in bag = 44
Color of marbles in bag : red, green
Number of red marbles = 11
The ratio of green to red marbles :
Number of green marbles :
(Total marbles in bag - number of red marbles)
(44 - 11) = 33 green marbles
Hence, ratio of green to red Marbles:
Number of green marbles : number of red marbles
33 : 11
3 : 1
Answer:
The correct answer is 2:1.

Answers
Answer:
25) B obtuse scalene
26) A acute isosceles
27) A acute isosceles
28) D obtuse isosceles
29) D right scalene
30) C obtuse isosceles
31) C obtuse scalene
32) C acute scalene
Step-by-step explanation:
A scalene triangle has sides of no equal measures (no side has the same length as another). An isosceles triangle has two sides of the same length. An equilateral triangle has three sides that all have the same lengths.
An acute triangle has all three angles that each measure less than 90°. An obtuse triangle has one angle that measures greater than 90°. A right angle has one angle that measures exactly 90°.

#1: Solve the linear system below using the elimination method. Type your
answer as an ordered pair in the form (#,#).*
2x + 5y = -16
-3x + 7y = -5
Answers
Answer:
[tex](-3,-2)[/tex]
Step-by-step explanation:
First, you need to get one like term in each equation the same in order to eliminate. To do less damage to the equation, we'll use the x terms.
To get the x terms the same, multiply both equations by the opposite x term:
[tex]-3(2x+5y)=-3(-16)\\\\2(-3x+7y)=2(-5)[/tex]
Simplify by multiplying. Use the distributive property for the left side (remember, two negatives make a positive and a negative multiplied by a positive will always be negative):
[tex]-3(2x)-3(5y)=-3(-16)\\\\2(-3x)+2(7y)=2(-15)\\\\\\-6x-15y=48\\\\-6x+14y=-10[/tex]
Now subtract all like terms. The x terms cancel out:
[tex]-6x-(-6x)=0\\\\-15y-14y=-29y\\\\48-(-10)=58\\\\-29y=58[/tex]
Now solve the new equation for y. Isolate the variable by using inverse operations. The term can be seen as -29×y. In order to isolate the variable, use division (opposite of multiplication). Divide both sides by 29:
[tex]\frac{-29y}{29} =\frac{58}{29} \\\\-1y=2[/tex]
Make the variable positive. Multiply both sides by -1:
[tex]-1(-1y)=-1(2)\\\\y=-2[/tex]
The value of y is -2. Insert this value into either original equation:
[tex]2x+5(-2)=-16[/tex]
Solve for x. Simplify multiplication:
[tex]2x-10=-16[/tex]
Use inverse operations to get like terms on the same side of the equation. Add 10 to both sides (addition is the opposite of subtraction) to cancel out the -10 on the left:
[tex]2x-10+10=-16+10\\\\2x=-6[/tex]
Isolate the variable using inverse operations. The x term can be seen as 2×x. Division is the opposite of multiplication, so divide both sides by 2:
[tex]\frac{2x}{2}=\frac{-6}{2} \\\\x=-3[/tex]
The value of x is -3. Therefore, the solution to the system is:
[tex](-3_{x},-2_{y})[/tex]

Answer:
It would be 1⅑
Step-by-step explanation:
First we turn the fractions into improper fractions.
4 7/9 would now be 43/9
3 2/3 would not be 11/3
Now, we have to make them have the same “bottom number”
3x11=33, 3x3=9
Now our equation is..
43/9 - 33/9 = 10/9
When we turn it into a simplified fraction, it would be 1⅑
