How do i do solving systems using elimination
Answer:
The elimination method for solving systems of linear equations uses the addition property of equality. You can add the same value to each side of an equation. So if you have a system: x – 6 = −6 and x + y = 8, you can add x + y to the left side of the first equation and add 8 to the right side of the equation.

i REALLYYY need help asappp,solving for x in angles
Answer: d=72
Step-by-step explanation:
Helpful hint whenever two lines cross the two angles created (95) and (d=13) =180
you can easily solve this by setting them equal to 180 or just subtracting 95=13 from 180

Point E is on line segment DF. Given DE=2x, EF=2x-6, and DF=3x+5, determine the numerical length of EF.
Answer:
[tex]DF = 38[/tex]
Step-by-step explanation:
Given
[tex]DE = 2x[/tex]
[tex]EF = 2x - 6[/tex]
[tex]DF = 3x + 5[/tex]
Required
Determine EF
Since E lies on DF, then
[tex]DF = DE + EF[/tex]
Substitute values for DF, DE and EF
[tex]3x + 5 = 2x + 2x -6[/tex]
Collect Like Terms
[tex]3x -2x -2x = -6 -5[/tex]
[tex]-x = -11[/tex]
Solve for x
[tex]x = 11[/tex]
Recall that
[tex]DF = 3x + 5[/tex]
Substitute 11 for x
[tex]DF = 3 * 11 + 5[/tex]
[tex]DF = 38[/tex]

A hiker is walking down a mountain. She walked 5978 feet in 17 minutes. In that time she descended 1024 feet feom the top of the mountain. She then walked 3927 feet in 7 minutes. In that time she descended 500 more feet. Express the average rate of change in altitude of the hiker from her starting point to her ending point as unit rate
Answer:
[tex]Average \ rate \ of \ change =[/tex] 63.5 ft/min
Step-by-step explanation:
Given that:
A hiker is walking down a mountain.
For the first case:
She descended 1024 feet from the top of the mountain in 17 minutes after walking for 5978 feet.
For the second case:
She descended 500 more feet from the top of the mountain in 7 minutes after walking for 3927 feet.
Thus; the average rate of change in altitude of the hiker from her starting point to her ending point can be expressed as:
[tex]Average \ rate \ of \ change = \dfrac{h_1 +h_2}{t_1 + t_2}[/tex]
[tex]Average \ rate \ of \ change = \dfrac{1024 +500}{17 + 7}[/tex]
[tex]Average \ rate \ of \ change = \dfrac{1524}{24}[/tex]
[tex]Average \ rate \ of \ change =[/tex] 63.5 ft/min

Julie's phone company charges her a monthly service fee of $35 plus and additional $0.10 per minute m, she uses. If her bill for the month of June is $140, what is the value of m?
Answer:
1,050
Step-by-step explanation:
Julie phone company charges her a monthly fee of $35
And also an additional $0.10 per minute
Her bill for the month of June is $140
Therefore the value of m can be calculated as follows
0.10m + 35= 140
0.10m= 140-35
0.10m = 105
m= 105/0.10
m= 1,050
Two walls measure 22 feet by 9 feet and two walls measure 26 feet by 9 feet. The ceiling measures 22 by 26. The floor has the same dimensions as the ceiling. What is the total wall area that will be painted? If a gallon of paint covers 144 square feet, how many gallons will we need?
Answer:
The total wall area is 864 ft²
The number of gallons of paint needed for the total wall area is 6 gallons.
Step-by-step explanation:
Given;
dimension of first two side walls = 22 feet by 9 feet
dimension of second two side walls = 26 feet by 9 feet
dimension of the ceiling = 22 by 26
The total wall area is given by;
A = 2(22 x 9) + 2(26 x 9)
A = 864 ft²
144 ft² ---------------1 gallon of paint
864 ft² --------------?
= 864 ft² / 144 ft²
= 6 gallons
Therefore, the number of gallons of paint needed for the total wall area is 6 gallons.

Is 4(3x – y) and 12x – 4y equivalent? yes or no, if so how is it? HELP ASAP PLEASE AND THANK YOU!
Answer:
Yes!
Step-by-step explanation:
If you distribute 4 into 3x-y, you will get the same thing (12x-4y) meaning they are equivalent.
Answer:
Yes
Step-by-step explanation:
4(3x - y) | 12x - 4y
12x- 4y = 12x - 4y
hence they are equivalent
Miss bell decorates her gazebo with colored lights. The base of the gazebo is a circle with a diameter of 12 feet. Using the same length of lights she's going to decorate the side of her garden shed which has a square base. What is the maximum side length of the shed
Answer:
The maximum side length of the shed = 9.42 ft
Step-by-step explanation:
From the given information:
Miss bell decorates her gazebo with coloured lights who base is a circle with diameter 12 feet. The first find the circumference of the gazebo by using the circumference of a circle since the base takes such shape.
Circumference of a circle = πd
Circumference of a circle = π × 12
Circumference of a circle = 37.699
Then; the circumference of the circle equates to the length of the lights.
However, using the same length, the maximum side length of the garden shed whose base took a square form can be determined by using the perimeter of a square as the square length, which is;
P = 4L
where;
L = length of sides
37.699 = 4L
L = 37.699/4
L = 9.42 ft
Thus, the maximum side length of the shed = 9.42 ft

Answer:
<NMP = 73
Step-by-step explanation:
First, the sum of angles in a quadrilateral is 360degrees.
All the angles are given, aside from <NMP (for this problem will be denoted as <M). One has to solve for <M.
given,
<N = 95,
<O = 90,
<P = 112
set up an equation
<N + <O + <P + <M = 360
95 + 90 + 112 + <M = 360
simplfy
297 + <m = 360
inverse operations
287 + <M = 360
-287 -287
<M = 73

The legs of an isosceles triangle have lengths 2x+1 and -3x+16 . The base has length 3x-5 . What is the length of the base? Guys am willing to give my points to you place someone help me.
Answer:
It'll be 4
Step-by-step explanation:
2x+1 = -3x+16 , you'll do the basic math which is put your X on one side and numbers on the opposite to get X.You're finding the base so you plug in the answer (you had gotten from 2x+1 and -3x+16), to 3x-5 and you get your answer 4

If A = -1 +5n2 + 9 and B = 3 – n, find an expression that equals 2 A – 3B
in standard form.
Answer:
10n² + 3n + 7
Step-by-step explanation:
2A - 3B = 2.( -1 + 5n² + 9) - 3.(3 - n)
= -2 + 10n² + 18 - (9 - 3n)
= 10n² + 16 -9 + 3n
= 10n² + 3n +7
