Solve the system using substitution. Show your work.
x = -4y + 9
x - y = 4

Answers

Answer:

please what should we found? is it the value of ×or y

x = -4y + 9
x - y = 4

- rearrange the second equation to x = 4 + y
- then we can plug it into x for the first equation

4 + y = -4y + 9 — then we solve for y
y = -4y + 5
5y = 5 -> y = 1

we can then plug in 1 (our y value) into the original second equation.

x - 1 = 4 -> x = 5

x = 5 & y = 1
you should put it in a coordinate layout so:
(5,1)

For her science fair project, Madelyn is growing crystals with sugar water. She wants to know if the size of the container affects crystal growth. To start, Madelyn pours a sugar-water mixture into a small bowl. Then she pours triple the amount of the mixture into a large bucket. She decides to add red coloring so the crystals are more visible. Madelyn adds the same amount of red coloring to both containers. Which container's sugar-water mixture is a darker shade of red?
no links

Answers

If the bowl mixture is 3 time smaller than the bucket mixture and she added the same amount of color

The smaller container of sugar-water mixture will have the darker shade of red.

What are arithmetic operations?

The four basic operations of arithmetic can be used to add, subtract, multiply, or divide two or even more quantities.

They cover topics like the study of integers and the order of operations, which are relevant to all other areas of mathematics including algebra, data processing, and geometry.

As per the given information in the question,

The experiment done by Madelyn is that,

Firstly, she has a small bowl where she pours as sugar-water mixture and in second case she pours tripe the amount of the mixture into a large bucket.

She adds the same amount of red coloring to both containers, then the smaller container or the small bowl will get the darker shade of red because the amount of mixture is less over there and the amount of color is same so, if you put the color in the larger one it will not get that red as compared to the smaller bowl.

Coach Cliffman made a deposit of $1,800 into an account that earns 2% annual compound interest. Find the amount of interest that Coach Cliffman earned after 3years.

Answers

Answer: 5508$

Step-by-step explanation:

So to find interest your formula is this:

Int=interest rate (percent)*principal

So your problem would be: int=.02*1800

This equals 36. Since its interest, you add your interest (36) and your principal (1800) and get 1836. Now, since you need to find the interest for 3 years, you multiply 1836 by 3.

Answer:

either 78.4cm or 288.4cm

Step-by-step explanation:

rectangle area

A = 15x4

A = 60

Area of 2 triangles

A = 4.6x4/2

A = 9.2x2

A = 18.4

18.4 + 60 = 78.4cm

Maybe the answer

Area of 2 rectangles

A = 15x4

A = 60

A = 15x14

A = 210

Area of 2 triangles

A = 4.6x4/2

A = 9.2x2

A = 18.4

60 + 210 + 18.4 = 288.4cm

either answer hope one is right

Answer:

228.4

Step-by-step explanation:

Both triangle surface:

4x4.6 and then divide by 2 = 9.2

That will be the surface for one triangle

But there are two triangles so we times that by 2

That will be 18.4

Both big rectangle surface: (the top and bottom ones)

15x5=75

But we have two rectangles

So we times that by two and the answer will be =150

Smaller rectangle: (the one between two triangles)

4x15=60

Okay, now we add them all up, the triangles and rectangles

60+150+18.4=228.4
