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]

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

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
Answer:
<NMP = 73

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
A pitcher contains 2 liters of lemonade. Each serving of lemonade is 1/8 of a liter. If 1.75 pitchers of lemonade are made, how many servings will this provide? Choose the answers from the drop-down menus that correctly complete the statement.
Answer:
Step-by-step explanation:
1 Pitcher= 2 liters lemonade
1.75 Pitcher = 3.5 liters of lemonade
since each serving have 1/8 of a liter this means each 1 liter of lemonade there will be 8 servings so in 3.5 liters of lemonade
3.5*8=28 servings

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.

A flagpole has a height of 66 yards. It will be supported by three cables, each of which is attached to the flagpole at a point 6 yards below the top of the pole and attached to the ground at a point that is 32 yards from the base of the pole. Find the total number of yards of cable that will be required
Answer:
The value is [tex]Y = 204 \ yards[/tex]
Step-by-step explanation:
From the question we are told that
The height of the flag pole is [tex]h = 66 \ yards[/tex]
The position of the cables on the pole with respect to its top is [tex]x = 6 \ yards[/tex]
The position of the cable from the base of the pole is [tex]w = 32 \ yards[/tex]
The number of cables is n = 3
Generally the length of one of the cable is obtained using Pythagoras theorem as follows
[tex]u = \sqrt{ (h - x)^2 + w^2}[/tex]
=> [tex]u = \sqrt{ (66 - 6)^2 + 32^2}[/tex]
=> [tex]u = 68 \ yards[/tex]
Generally the total number of yards of cable that will be required is mathematically represented as
[tex]Y = 3 * u[/tex]
=> [tex]Y = 3 * 68[/tex]
=> [tex]Y = 204 \ yards[/tex]

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
