Substitution would be the best method for solving which system?
O x = 6
2x - 3y = 8
3x - 2y = 18
4x + 5y = 60
O x + y = 7
x - 4y = 12
O y = 2x
x + y = 28
Answer:
The last one
Step-by-step explanation:
Because it tells you what y is
Answer:
Assuming its asking which is the easiest one to use substitution its the last one: y= 2x : x + y = 28
Step-by-step explanation:
Because y and x are already one opposite sides you can substitute y in the 2nd equation with 2x. So you'll get 3x = 28 so x = 9.333333334. Then you plug your answer for x in the original equation to get y = 18.666666667
4x^2-y^2 how do you factorize this? with steps pls:)
===========================================
Work Shown:
4x^2 - y^2
(2x)^2 - (y)^2
(2x-y)(2x+y)
When going from the second step to the third step, I used the difference of squares rule. That rule is a^2-b^2 = (a-b)(a+b). In this case, a = 2x and b = y.
Side note: (2x-y)(2x+y) is the same as (2x+y)(2x-y). We can multiply in any order.
Help me please ASAP show work pls btw

Mrs. Davis is building a storage shed that is 12 feet long and 8 feet wide. Construct a scale drawing of the shed. Use a scale of 1/2 inch = 8 feet
Answer:
3/4 inch by 1/2 inch (length - width)
Step-by-step explanation:
If 1/2 inch equals 8 feet on the scale drawing, this means that 1/4 inch on the scale drawing equals 4 feet, by dividing 2 on both sides.
The storage shed is 12 feet long, and 4 feet on the scale drawing equal 1/4 inch. By multiplying the scale of 1/4 inch = 4 feet by 3 on both sides, we get 3/4 inch = 12 feet. This means that the length of the storage shed can be represented by 3/4 inch.
Since 1/2 inch equals 8 feet and the width of the storage shed is 8 feet, the width can be represented by 1/2 inch on the scale drawing.
How long must a rectangular box be in order to hold 1.800 cubic centimeters if its width is 12 centimeters and its height is 6 centimeters?
Answer:
25 cm
Step-by-step explanation:
V = lwh
1800 = l(12)(6)
l = 1800 / (12×6)
l = 1800/72
l = 25
i’m confsued…can someone help :)
Answer:
First we will find the surface area of the right triangle.
area of the right triangle=1/2*base*height.
now multiply it by 2 then we will get the S.A of both the right triangles.
Now, the other seems to be a rectangle,so find its area. And also the unseen side is a rectangle so find its area also .
And. now at the last. plus. the area of all the sides. you will get your answer. understand buddy.
please help meeee! I have a math test tomorrow and I need this finished asap , ty :)

Find the slope please!
Explanation:
The two points (0,0) and (2,1) are on the line. Apply the slope formula to them to get the following
m = (y2-y1)/(x2-x1)
m = (1-0)/(2-0)
m = 1/2
This indicates that each time you go up 1 unit, you must move to the right 2 units.
Slope = rise/run = 1/2
rise = 1, run = 2
About 142 million people in the United States watch online videos. If 44.02 watch news stories, about what percent watch news stories?

Simplify this;
what is -2x + x?
Answer:
-x
Step-by-step explanation:
Note that when there is a standalone variable (such as the x in this example), it typically actually means 1x. (If it is -x, it will be -1x.) However, you do not write 1 in front, as it is presumed.
Subtract the coefficient of each terms:
1x - 2x = -1x
-x is your simplified form.
What method can be used to prove the triangles below are congruent?
Answer:
B. Not congruentStep-by-step explanation:
According the the picture we have:
The triangles have two congruent sides and one non-included angle.It means we don't have sufficient information to state the triangles are congruent.
Correct choice is B

The Triangles shown in the above image are not congruent, because no congruency criteria can be used through given information to prove that they are congruent.

3(2x+4)=−36
Find the variable
Answer:
x=8
Step-by-step explanarion:
Step 1
multiply the parenthesis with the factor 3
6x+12=-36
now, subtract 12 from -36
6x=-48
and finally we divide 6 by -48
and are left with
x=-8
