Answer:
let x be chips and y be sodas
8x + 4y = 5 ---> for the first hint
4x + 8y = 7------> second hint
0.25 cents is how much chips costs
and 0.75 cents is how much sodas costs
Answer: Each bag of chips is $0.25, each soda is $0.75.
(0.25 x 8) + (0.75 x 4) = 5
2 + 3 = 5
(0.25 x 4) + (0.75 x 8) = 7
1 + 6 = 7

Answer:
x = - 3
Step-by-step explanation:
Given
4x + 1 = 2x - 5 ( subtract 2x from both sides )
2x + 1 = - 5 ( subtract 1 from both sides )

A.Translation
B.Dialation
C.Reflection
D.Rotation
Reflection. A reflection is what appears to be the same distance from the other side of the mirror.
Two lines, A and B, are represented by the equations given below!
Line A: y = x - 4
Line B: y = 3x + 4
Which of the following shows the solution to the system of equations and explains why?
A. (-3,-5), because the point satisfies ONE of the equations
B. (-3,-5), because the point lies between the two axes
C. (-4,-8), because the point satisfies BOTH equations
D. (-4,-8), because the point does not lie on any axis
Answer:
The solutions to the system of equations are:
[tex]y=-8,\:x=-4[/tex]
Thus, option C is true because the point satisfies BOTH equations.
Step-by-step explanation:
Given the system of the equations
[tex]\begin{bmatrix}y=x-4\\ y=3x+4\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y-x=-4\\ y-3x=4\end{bmatrix}[/tex]
[tex]y-3x=4[/tex]
[tex]-[/tex]
[tex]\underline{y-x=-4}[/tex]
[tex]-2x=8[/tex]
[tex]\begin{bmatrix}y-x=-4\\ -2x=8\end{bmatrix}[/tex]
solve for x
[tex]-2x=8[/tex]
Divide both sides by -2
[tex]\frac{-2x}{-2}=\frac{8}{-2}[/tex]
[tex]x=-4[/tex]
[tex]\mathrm{For\:}y-x=-4\mathrm{\:plug\:in\:}x=-4[/tex]
[tex]y-\left(-4\right)=-4[/tex]
[tex]y+4=-4[/tex]
[tex]y=-8[/tex]
The solutions to the system of equations are:
[tex]y=-8,\:x=-4[/tex]
Thus, option C is true because the point satisfies BOTH equations.

A cow is eating green grass that grows in a field.
Which type of organism is the grass in this scenario
consumer
decomposer
prey
producer
A cow is eating green grass that grows in a field. The grass in this scenario is the producer.
'This is a basic food chain. The grass is a living organism that utilizes energy from the sun to make its own food through an interaction called photosynthesis. Then, different creatures eat the grass; it is their wellspring of energy.
Every living organism (plants and creatures) should eat food for the endurance of some sort or another. Plants make their own food through an interaction called photosynthesis. Using the energy from the sun, water, and carbon dioxide from the air and nutrients, they artificially make their own food. Since they make or produce their own food they are called makers.
Organisms that don't make their own food should eat either plants or creatures. They are called buyers. A few creatures get their energy from eating plants while different creatures get energy in a roundabout way from plants by eating different creatures that previously ate the plants.
Creatures that eat just plants are called herbivores. Creatures that eat the two plants and other creatures are called omnivores. Creatures that eat just different creatures are called carnivores.
A few creatures eat just dead or decaying materials and are called decomposers.

A $120 wagon is on sale for 15 percent off. What is the sale price of the wagon?
$18
$102
$105
$108
Answer:
The answer is $102.
Step-by-step explanation:
The main question here is, what is the sale price of the wagon?
1. Let's compute for 15% of 120.
15%×12015/100×1203/20×1203×6182. So now let us subtract 18 from 120.
You should get 102.Hope this helps and if you could mark this as brainliest. Thanks!
The required sale price of the wagon is $102. So the correct answer is an option (b).
What is the percentage?The percentage is the ratio of the composition of value to the overall composition of value multiplied by 100.
Here, to calculate the sale price of the wagon, we need to find out the discount amount first, and then subtract it from the original price.
Discount amount = 15% of $120
= 0.15 x $120
= $18
Sale price = Original price - Discount amount
= $120 - $18
= $102
Therefore, the sale price of the wagon is $102. So the correct answer is an option (b).

Lucia invests $5000 at a rate of 4.5% per year compound interest. Calculate the value of her investment at the end of 7 years.
The value of her investment at the end of 7 years is $11804
How to determine the value?The given parameters are
Principal, P = $5000
Rate, r = 4.5%
Time, t = 7 years
The value is then calculated as:
Value = P * P(1 + r)^t
So, we have:
Value = 5000 + 5000 * (1 + 4.5%)^7
Evaluate the expression
Value = 11804
Hence, the value of her investment at the end of 7 years is $11804

Seth's father is thinking of buying his son a summer movie pass for $30 dollars.
With the pass, matinees cost $3 each. Without the pass each movie is normally
$8. If Seth plans to go to 30 movies this summer how much money would he
save? ONLY PUT THE NUMBER, NO DOLLAR SIGN.
Answer:
120
Step-by-step explanation:
First, you have to calculate the money that Seth would spent if he goes to 30 movies if his father gets the summer movie pass by adding up the cost of the pass plus the result of multiplying the cost per movie with the pass for the number of movies:
30+(3*30)=30+90=120
Second, you need to calculate the money that Seth would spent if he goes to 30 movies without the pass by multiplying the normal price per movie for the number of movies:
8*30=240
Third, you need to find the difference between both costs:
240-120=120
According to this, the answer is that if Seth plans to go to 30 movies this summer, he would save 120.

Priya has a recipe for banana bread. She uses 7 1/2 cups of flour to make 3 loaves of
banana bread.Andre will follow the same recipe but only wants to make one loaf of
bread. How much flour will Andre use?
Answer:
2 1/2 cups of flour
Step-by-step explanation:
Priya is making 3 loaves of bread, so she will use 7 1/2 cups of flour.
Andre is making 1 loaf of bread, which is 1/3 the amount of loaves Priya is making. So, he will be using 1/3 the amount of flour Priya is using. So all we have to do is take 7 1/2 and divide it by 3:
7.5/3 = 2.5
Andre will use 2 1/2 cups of flour.
If sin t = -8/17 and t is a quadrant III angle, find cot t
Answer:cot t = 1.875
[tex]sin t=\frac{-8}{17}[/tex] but sin²t + cos²t = 1 ⇔ cos²t = 1 - sin²t
⇔cos t = [tex]\sqrt{1-sin^{2}t }=\sqrt{1-(\frac{-8}{17})^{2} }=|\frac{15}{17}|[/tex]
but t is a quadrant III angle => cos t = [tex]\frac{-15}{17}[/tex]
=> cot t = [tex]\frac{-15}{17}:\frac{-8}{17}=\frac{15}{8}=1.875[/tex]

D. about 50%
Answer:
C. about 15.4%
Step-by-step explanation:
There are 52 cards in a deck
There are 4 kings and 4 aces
so, 8/52 is the chance of getting either of those two.
8/52 is about 0.1538 or 15.38%
15.38% rounded would be 15.4%

Answer:
130%
Step-by-step explanation:
Let x be the unknown number.
of the unknown number = [tex]\frac{13}{10}[/tex] [tex]x^{}[/tex]= 1.3x
We need to find the [tex]\frac{13}{10}[/tex] of a number is what percent of that number.

Substitute 1.3x for new value and x for initial value in the above formula.
%=[tex]\frac{1.3x}{x}[/tex]x 100
Cancel out the common factors.
%= 1.3 x 100
%= 130
Therefore, [tex]\frac{13}{10}[/tex] of a number is 130% of that number.
