Step-by-step explanation:
The diagonals of a rectangle are equal.
2x + 10 = 56 That minus sign can't be there. Subtract 10 from both sides.
2x = 56 - 10 Combine
2x = 46 Divide by 2
x = 46/2
x = 23
Ren was trying to solve a system of linear equations. He correctly argued that he could replace one equation by the sum of that equation and a multiple of the other. H
produce a system that has the same solution as the original system.
To show this, Ren wrote down a system of equations. He then determined which other systems of equations would have the same solution as his original system. Rem
below.
-2x - 5y = -47
4x - 2y = -2
Complete the table below to determine which system(s) of equations has the same solution as the original system shown above. Choose Has the Same Solution or Do
for each system of equations.
Has the Same Solution Does Not Have the Same Solution
-14x + y = -41
4x - 2y = -2
-2x - 5y = -47
6x + 3y = 45
-2x - 5y = 47
8x - 5y = -8

Step-by-step explanation:
What could be the answer?
Answer:
D = 1 8.87961173
Round off to the whole number
D= 19m
Explanation of results
So to find d you will use the trigonometry formula
So you are given the
Degree which is 39°
and the hypotenuse which is 30m
Using the sin θ = Opposite Side/Hypotenuse you are going to put in the numbers where they should go in the formula so,
[tex] \sin(39) = \frac{d}{30} [/tex]
then you are going to isolate d on the right by multiplying 30 on both sides.
It will look like
30 Sin 39
So, just put this in the calculator
Solve the following system of equations by substitution. Make sure to check your solution. x + y = 5 3x - y = -5
Answer:
(0.5)
Step-by-step explanation:
x + y = 5
3x - y = -5
Put "y" on one side to isolate
3x - y = -5
3x = y - 5
3x + 5 = y
Plug "3x + 5" in for "y" in the second equation
x + (3x + 5) = 5
4x + 5 = 5
4x = 0
x = 0
Plug "0" in for "x" in any one of the equations
0 + y = 5
y = 5
To check, plug in "0" for "x" into the first equation and make sure they get the same answers
3(0) - y = -5
0 - y = -5
y = 5
Mrs. Anderson's car can go 464 miles on 16 gallons of gasoline. How many miles
can the car travel on 22 gallons of gasoline?
Answer:
638 miles
Step-by-step explanation:
Key skills needed: Proportions, Unit Rates
1) The car can go 464 miles with 16 gallons of gasoline. We need to find how many miles each gallon gasoline results in.
To find the miles per gallon, we would do 464 miles/16 gallons --> 29 mpg
This means each gallon lets the car run 29 miles.
2) To find out how many miles 22 gallons is, we then do 29 x 22, which is 638 miles.
Therefore, your answer is 638.
Hope you understood and have a nice day!!

Find the total surface area of this prism where the cross-section is an isosceles triangle
please help me
I am giving 25 points.
Answer:
620 cm²
Step-by-step explanation:
First I'll describe the net. There are 3 rectangles and 2 triangles. The triangles are identical and 2 out 3 of the rectangles are the same.
So, we know that the two similar rectangles have measurements of 13cm x 10cm. So, that's 130 cm² for one such rectangle. Add the other one and we get 260 cm².
The bottom rectangle has dimensions of 10cm x 24 cm, or 240 cm². Add that to our previous total and we'll get 500 cm².
On to the triangles. Now, we know that 1. these are isosceles triangles, and 2. they have a height of 5 cm. We can pretend to cut them in half at their highest point, which would give us 4 triangles with height 5 and length 12. Now, if you put two identical triangles together, it's a four-sided shape, and you can just multiply length by width. Let's do that.
Now we have 2 rectangles, each with width 5 and length 12. Calculate the area for each, and now we have 2 rectangles with area 60 cm². Add them together....120cm².
Add that to our previous total, and we'll get 620 cm². That should be the surface area of your prism :D

Explain what a markdown is.
Answer:
Basically a reduction in price
Step-by-step explanation:
In finance, a markdown is a reduction in the price and value of an asset. ... Markdowns are designed to increase sales, so they usually occur when a business cannot sell a product at its current price. By reducing the price, a markdown makes a good or service more desirable for customers.

According to a recent survey, 47 percent of the people living in a certain region carry a certain genetic
trait. People from the region will be selected at random one at a time until someone is found who carries
the genetic trait. Let the random variable X represent the number of people selected to find one person
who carries the genetic trait. How many people from the region can we expect to be selected to find one
person who carries the genetic trait?
Answer:
2.13
Step-by-step explanation:
.47 would be your probability of randomly selecting but your'e solving geometrically so think how many trials until successful.
use u x(mean)= 1/.47 to get around 2.13
Answer:
2.13
Step-by-step explanation:
.47 is the probability of randomly selecting, you have to find how many trials until successful. x(mean)= 1/.47 to get around 2.13

The length of a rectangle is five inches less than three times its width. If the perimeter
of the rectangle is 150 inches, find the dimensions.
L=40 in. ; W=35 in.
L=60 in. ; W=45 in.
L=50 in. ; W=25 in.
L=55 in. ; W=20 in.
Answer:
L = 55 in, W = 20 in
Step-by-step explanation:
Hi there!
First we have to set up an equation for the length, which can be written as 3x - 5.
The formula for perimeter of a rectangle is 2l + 2w = p, so we can plug in some values here.
l = 3x - 5
w = x
[tex]2(3x-5) + 2(x) = 150[/tex]
Now we just have to solve!
[tex]6x - 10 + 2x = 150[/tex]
When we combine like terms and add ten to both sides, we are left with
[tex]8x = 160[/tex], which means x = 20
Using this, that means the width is 20
We can find the perimeter by plugging 20 in for x. [tex]l = 3(20) -5[/tex]
This means the length is 55.

An art shop has 80 large boxes of markers and 34 small boxes of markers in stock. Each large box contains 48 markers and each small box contains 20 markers. Which equation could be used to find n, the total number of markers in stock?
Answer: n= 80 ×48+ 34×20
Step-by-step explanation:
Given: Number of large boxes = 80
Number of small boxes = 34
Number of markers in each large box = 48
Number of markers in each small box = 20
Total markers = (Number of large boxes)x (Number of markers in each large box) + (Number of small boxes) x (Number of markers in each small box)
Total number of markers = n (given)
Then, n= 80 ×48+ 34×20
Therefore , the equation could be used to find n, the total number of markers in stock: n= 80 ×48+ 34×20
