Billy purchased 9 types of one type and 16 types of another spinner.
What is the system of equations?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
Billy bought 25 spinners.
Let x and y are the type of spinners.
Then, x + y = 25 {equation 1}
Some were $10 and some were $15.
10x + 15y = 295
Simplifying,
2x + 3y = 59 {equation 2}
Multiplying 2 to the equation 1 and subtraction the equation 2,
-y = -9
y = 9
And x = 16
Therefore, each type of spinner is 9 and 16.

Santiago is trying to earn experience points in his newest game. He knows that finding
gophers will get him the most points. His number of experience points after his first attempt
can be represented by the linear equation - 24x + 2y = 900, where y represents Santiago's
total number of experience points and x represents the number of gophers he finds.
What is the slope of the line? What does this represent?
F The slope is 12; he earns 1 point for every 12 gophers he finds.
G The slope is 450; he earns 1 point for every 450 gophers he finds..
# The slope is 12; he earns 12 points for each gopher he finds.
J The slope is 450; he earns 450 points for each Igopher he finds.

PLEASE HELP ME!!! I'M ALMOST OUT OF TIME!!
Answer:
I am confused what the question is asking
Step-by-step explanation:
Could you please comment down below and restate the question?
Answer: ok so.. exponential function's is kinda the same process as slopes and linear equations and functions ok so........
For slopes its rise over run but for this question its...... TO BE CONTINUED LOL (go to the explanation)
Step-by-step explanation:
So for the run on the x axis its 7 you can see it goes upward a little bit on the 7 but the 7 still counts :D
ok so we got 7 and as the line rises 9go to the picture added for more understanding) So as the line rises we can see from were i marked it in the picture that it touches the 2. So we got 2 as the rise and 7 as the run but remember this is not slopes lol so its kinda different.

4(3x-5)-2(5x-7) please help me i’m not it’s if it’s 2x-6 or 2x-3
Answer:
2x-6
Step-by-step explanation:
4(3x-5)-2(5x-7)
(12x-20)-(10x-14)
12x-20-10x+14
12x-10x-20+14
2x-6
Answer:
=> first multiply the numbers in bracket
4(3x-5)-2(5x-7) when we multiply for 4 and -2
12x-20-10x+14
=> then collect the like terms
12x-10x-20+14
=> 2x-6

At Wegmans a 12 pack of paper towels costs $15.72. At Tops a 10 pack of paper towels cost $13.35. Which store has the better buy? What is the difference in unit prices?
Answer:
Wegman's, roughly 3 cents
Step-by-step explanation:
Divide the price by the number of paper towels in the pack to get the unit price.
$15.72/12= $1.31
$13.35/10= $1.335, round since it's money, $1.34
$1.34-$1.31= $0.03 or 3 cents
Wegmans has the better buy, as their unit price is lower.
The difference in unit prices between the two stores is $0.03 per paper towel.
To determine which store has the better buy, we need to compare the unit prices of paper towels at both Wegmans and Tops.
The unit price is the cost per paper towel.
For Wegmans:
Cost of 12 pack of paper towels = $15.72
Number of paper towels in the pack = 12
Unit price at Wegmans = Total cost / Number of paper towels
Unit price at Wegmans = $15.72 / 12 = $1.31 per paper towel
For Tops:
Cost of 10 pack of paper towels = $13.35
Number of paper towels in the pack = 10
Unit price at Tops = Total cost / Number of paper towels
Unit price at Tops = $13.35 / 10 = $1.34 per paper towel
Now, we compare the unit prices:
At Wegmans, the unit price is $1.31 per paper towel.
At Tops, the unit price is $1.34 per paper towel.
The store with the lower unit price has the better buy.
In this case, Wegmans has the better buy, as their unit price is lower.
To find the difference in unit prices:
Difference in unit prices = Unit price at Tops - Unit price at Wegmans
Difference in unit prices = $1.34 - $1.31 = $0.03 per paper towel
So, the difference in unit prices between the two stores is $0.03 per paper towel.

When finding the area of a quadrilateral, what operation would I use and why?
Use the formula width x height = area. If the width is 4 inches and the height is 2 inches, the area equals 8 inches squared.
the measure of one angle of an isosceles trapezoid is x and the angle opposite it is x+20,what is the value of x
Answer:
X=80
Step-by-step explanation:
I suppose the graph will be like this:
Since isosceles trapezoid, red lines are parallel.
X+x+20= 180
2x+20=180
2x=160
X=80

You pay $3 per square foot for carpeting. Which equation can be solved to find the
amount you will pay to cover a triangular section of the floor with a base of 2 yards and
a height of 5 yards?
Answer:
$135
Step-by-step explanation:
Step 1
Conversion
Base = 2 yards
1 yard = 3 feet
2 yards = x
Cross Multiply
x = 2 × 3 feet = 6 feet
Height = 5 yards
1 yard = 3 feet
5 yards = x
Cross Multiply
x = 5 × 3 feet = 15 feet
Step 2
Find the area of the triangle
Area of a triangle = 1/2 × base × height
Base = 6 feet
Height = 15 feet
Area = 1/2 × 6 × 15
= 45 square feet
Step 3
Find the cost of the carpet
1 Square foot = $3
45 square feet = x
Cross Multiply
x = 45 × $3
x = $135
Therefore, the amount you will pay to cover a triangular section of the floor is $135

What does A equal: 3(6a+12)=9
Answer:
a = -3/2
Step-by-step explanation:
3(6a+12)=9
Divide each side by 3
3/3(6a+12)=9/3
6a+12 = 3
Subtract 12 from each side
6a+12-12 = 3-12
6a = -9
Divide by 6
6a/6 = -9/6
a = -3/2
3(6a+12)=9
distribute
18a+36=9

Luis plans to purchase some new baseball bats and gloves before spring training begins. Luis wants to buy the same bats and gloves he purchased last spring, but he can’t remember the price of each item. Luis recalls making two purchases last spring, each totaling $135 and both tax exempt. The first purchase was for a glove and three bats. The second purchase was for two gloves and a bat. If the current prices of these items are the same as last spring, how much will Luis pay this spring for three gloves and four bats?
Answer:
Luis will pay for three gloves and four bats = $ 270
Step-by-step explanation:
Let the bats be represented by b and gloves by g, then according to the given conditions
3b+ g= $135----equation 1
b+ 2g= $135------equation 2
Subtracting equation 2 from eq. 1 gives
3b+ g= $135----equation 1
-b -2g= -$135------equation 2
2b -g = 0 --------- equation3
2b-g= 0
or 2b= g------ equation4
This means price of 2 bats is equal to price of 1 glove.
Putting value of g in eq. 1 from eq. 4
3b+ 2b= $ 135
5b= $135
b= 135/5= 27
Price of 1 bat = $ 27 and price of 1 glove= 2*27= $54
Luis will pay for three gloves and four bats
= 54*3 + 4*27
= 162+ 108
= $ 270

othe large one is 234 i ran out of time sorry i didnt get circleto t
Step-by-step explanation:
Answer:
347.04 m²
Step-by-step explanation:
Total surface area = central rectangular prism + (1/2 left + 1/2 right)cylinder
a = 2x(11x3+11x6+6x3) + (2xπx(6/2)²+2xπx(6/2)x3)
= 234 + 113.04
