Solve For X And Y NEED FOR TEST

Answers

Answer 1

Answer:

x = 4 and y = 6

Step-by-step explanation:

With the way the equations are set up, substation is faster.

Just substitute -1/2x + 8 for the y in the first equation.

3x + 4(-1/2x + 8) = 36


And then you can just solve the equation. You would get x = 4.

Substitute 4 for x.

y = -1/2(4) + 8

y = 6

Answer 2
X=4 Y=6 have a great day or night where ever you are and goodluck on your assignment :)

Answer:

A = 1792.44

Step-by-step explanation:

Area of Trapezoid formula is:

A = 1/2(b1 + b2)h

A = 1/2(92+61.2)23.4

A = 1/2(153.2)23.4

A = (76.6)*23.4

Adam is purchasing a new television that costs $2,187.96 after tax. He borrowed the money from his parents and must pay back the full amount plus simple interest at the rate of 3.5%. What is the total amount he will pay if he takes 2 years to pay his parents back? (Include Decimal with the cents; No Commas)

Answers

He will pay 2264.54 with 3.5% interest
It is determined that he will pay an interest of $153.16 using simple interest and taking the exercise's specified criteria into account.
Basic Interest
When there is only one compounding every time period, simple interest is applied.
The formula for calculating interest after t years is 1 = Prt.
Where P is the initial sum and r is the interest rate in decimal form.
The following are the parameters for this problem:
P = 2187.96, r = 0.035, t = 2.
The interest will therefore be paid at the rate of 1=Prt = 2187.96 x 0.035 2 = $153.16.

The tape diagram represents an equation. Write an equation to represent the image.

Answers

Answer: 6t = 9

Step-by-step explanation:

What is visually explicable is that the 2 tape diagrams are equal.

One tape diagram equals 9, one is divided into 6 equal parts, each equals t.

6t's make up a diagram that is equal to a diagram equal to 9.

therefore 6t=9

the answer is 6t=9 I think it’s right

tan theta = 28/47 give your answer in 1 dp

Answers

Using a calculator, we get:

theta = tan^-1(28/47) â 32.7 degrees

Therefore, the answer is 32.7 degrees (1 dp).

b the higher the price the bigger the box is looking for another answer though so hold on

Answer:

See below.

Step-by-step explanation:

a) $81235 - $15405 = $65830

b)

1) The graph uses cubes to represent the amount of sales.

2) I wonder if the amount of sales is proportional to the length of the side of the cube or to the volume of the cube.

c)

Using a ruler, the Year 1 cube has side length 5 units.

Using the same ruler, the Year 5 cube has side length 18 units.

The volume of the Year 5 cube is 5832 units³. The volume of the Year 1 cube is 125 units³.

The ratio of the volumes of Year 5 cube to the Year 1 cube is

5832/125 = 47:1

The ratio of sales of Year 5 to Year 1 is

81235/15405 = 5:1

The sales of Year 5 are approximately 5 times the sales of Year 1, tbut the cube of Year 5 has approximately 47 times the volume of the cube of Year 1. The graph is misleading because the volumes of the cubes are not proportional to the amounts of sales.

d) 47 times in volume

Myla has a storage box that is 4 ft. high, 2 ft. long, and has a volume of [tex]16ft^{3}[/tex]


What are the widths of Kyle and Myla's boxes? Explain how you know.



help please! and please have easy explanation that's easy to understand :))

Answers

Answer:

OK so, volume= length x width x height

so, if the length of kyles box is 2, and his height is 3, but the volume is 12, then the width would be 2.

2 x 2 x 3=12

however, for myla, if her box is, 2 feet long and 4 feet high, but the volume is 16, then, her width is also 2.

2 x 2 x 4= 16

a way to look at this is, in the problem you are given the height and length, so, if its length times width times height, take your given length and multiply it by a number that will make it equal your given volume.

for example, let q=width, let m=height, and let j=length, p=volume, h=random variable.

j (x) h (x) m=p

its your job to find h.

Suppose instead that one friend bought all 4 bags of pretzels and another friend bought all 4 drinks write an expression that shows the total cost

Answers

Could you provide all the information

Answer:

4x+4y=total cost

Step-by-step explanation:

We are given that there was a total of 4 bags of pretzels and 4 drinks bought.  We are also given to write an expression using x dollars for the pretzels and y dollars for the drinks.

To do this, we need to multiply the cost of each pretzel bag, x, by the total amount of bags of pretzels purchased.

4·x

=4x

Next, we need to multiply the cost of each drink, y, by the total number of drinks purchased:

4·y

=4y

The question is asking us to write an expression, so put 2 and 2 together:

4x+4y=total cost

Given the actual question, "Suppose instead..." the expression would be the same.

Hope this helps! :)

5 Figure N is a rectangular prism that has twice the volume of figure M. How many layers and how many cubes in each layer could there be in figure N?​

Answers

The number of layers of M and in N in 2

How many layers and how many cubes in each layer

We do know that Figure N has twice the volume of Figure M. Since both figures are rectangular prisms, their volumes can be calculated using the formula:

Volume = length x width x height

Let's say that Figure M has a length of L, a width of W, and a height of H.

Then its volume is:

Volume_M = LWH

Since Figure N has twice the volume of Figure M, we can write:

Volume_N = 2 x Volume_M

Substituting the formula for Volume_M, we get:

Volume_N = 2LWH

This means that two layers of M and in N

The number of cubes cannot be determined with the available information

The number of times Maria drove the car on day 4 is 7 times.

How many times did Maria drive her car on day 4?

A line graph is a graph that connects different data points on a graph using a straight line. A line graph is made up of a x-axis and a y-axis. In the line graph given, the number of days is on the x-axis and the number of times the car was driven is on the y-axis. A line graph is used to show quantitative data. Line graphs are used to visualise data.

In order to determine the number of times Maria drove the car on day 4, locate where day 4 is on the x-axis. Then trace 4 upward toward a data point. When the data point is located, trace it to the y-axis. When day 4 is traced to the y-axis, the value gotten is 7.
