[tex]\qquad[/tex] ☀️It's given, the fifth part of a number when increased by 5 equals its fourth part decreased by 5.
[tex]\qquad[/tex] According to the question :-
[tex]\qquad \pmb{\sf\longrightarrow \dfrac{x}{5} + 5 = \dfrac{x}{4} - 5}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow \dfrac{x}{5 }- \dfrac{x}{4} = -5 -5}[/tex]
[tex]\qquad \pmb{\sf\longrightarrow \dfrac{(4x - 5x)}{20} = -10}[/tex]

solve each system of equations by substitution
-4x+y=-5 and 2x+y=7
Answer:
x = 2 and y = 3
Step-by-step explanation:
-4x + y = -5 -------------------(I)
y = 4x - 5 ------------(II)
2x + y = 7 -------------------(III)
Substitute y = 4x - 5 in equation (III)
2x + 4x - 5 = 7
6x - 5 = 7
Add 5 to both sides
6x = 7 + 5
6x = 12
Divide both sides by 6
x = 12/6
x = 2
Plugin x = 2 in (II)
y = 4*2 - 5
y = 8 -5
y = 3
not sure what to do here plz help
am i looking for the slope or what??
Solve for each variable. Remember to SHOW YOUR WORK!
3(4n − 2) = 2n + 74
Answer:
n = 8
Step-by-step explanation:
3(4n − 2) = 2n + 74
12n - 6 = 2n + 74
12n - 2n = 74 +6
10n = 80
divided by 10
n = 8

–7
–3
0

i forgot how?
Answer:i can see what you write?
Step-by-step explanation: send it again
the y-intercept would be (0, -7) because that’s where it crosses on the y axis
if 5y -4 = 21, then y=
5y-4 = 21
Add 4 on both sides to isolate y. (get rid of -4)
5y = 25
Divide 5 on both sides to solve for y.
y = 5
Answer:
Y is equal to 5
Step-by-step explanation:
5y - 4 = 21
5y = 21+4
5y = 25
Y = 25 ÷5
Y = 5

Answer:
A --> 57
Step-by-step explanation:
you can find the linear pair on YH by getting 180 and subtracting it by 106 giving 74. Add 74 and 49 to get 123. The rule with triangles is that all angles inside one equal 180 so get 180 and subtract it by 123 which gets you 57.
Hello I need help
A farmer wants to fence in a rectangular area that is mile wide by mile long, as shown in the picture.
Which of the following proportions can the farmer use to calculate how many feet of fencing he will need?
No links pls 100 pts
Answer:
its number four the last one
Step-by-step explanation:
Answer:
[tex]\frac{\frac{3}{4} mi}{x}[/tex]=[tex]\frac{1 mi}{5,280 ft}[/tex]
Step-by-step explanation:
First find the perimeter of the rectangle to see the total length
2([tex]\frac{1}{8}[/tex])+2([tex]\frac{1}{4}[/tex])
[tex]\frac{3}{4}[/tex]
Then, because you are converting from miles to ft, you can use the ratio of miles/feet to determinte the correct ratio for the perimeter.
The correct ratio is [tex]\frac{1 mi}{5,280 ft}[/tex]
To set these ratios equal to eachother, first see that one side of the equation has miles as the unit, the other side has miles/feet, so you must divide the perimeter by feet to set the ratios equal to eachother.
Therefore, the correct equation is [tex]\frac{\frac{3}{4} mi}{x}[/tex]=[tex]\frac{1 mi}{5,280 ft}[/tex]

Help me please. It’s for my geometry class and I don’t understand it.
Answer:
the answer is 29 degrees
Step-by-step explanation:
180 is the total of all the angles added together so if you subtract the 122 from 180 and divide by 2 you can get 29 for both and if you add it all together you should get 180 :)
Answer:
29
Step-by-step explanation:
pretty ez, so like a triangle got 180 degress total. what u gota do my man, is substract 122 from it. And u get 58 and they both are equal so u divide by 2 and u get 29.

Find the area of the green region
Answer:
Step-by-step explanation:
so imagine each of the 4 white spaces are like 1/4 of a circle. In this case 3.5 cm would be the radius(r) of the circle, agree?
the area of a circle is pi * r²
pi =~3.14
circle area = 3.14 * (3.5 * 3.5)
circle area = 3.14 * 12.25
circle area = 38.465 cm²
Ok, now that we have the white area, the green area is basically the full area of the square minus the white area, agree?
the side of the square is 3.5 + 3.5, which is 7 cm
square area = 7 * 7
square area = 49 cm²
green area = 49 - 38.465
green area = 10.535 cm²

Basic addition.
If each of the following quadrilaterals are trapezoids, find the missing measures. Show your work.
Answer:
Step-by-step explanation:
Since this is a trapezoid, then we have TS is parallel to QR
so we have:
[tex]\angle T+\angle Q = 180^\circ\\\angle S + \angle R = 180^\circ[/tex]
since[tex]\angle T = 91^\circ, \angle R = 27^\circ[/tex]
The measure of angle Q is 89 degree
The measure of angle S is 153 degree

Square Root of 24, 5, 31/6, 5.7
Answer:
(greatest to least) 5.7, 31/6, 5, √24,
Step-by-step explanation:
Evaluate the square root.
√24 ≈ 4.9
Evaluate the fraction.
31/6 ≈ 5.17
The numbers are now 5, 4.9, 5.17, and 5.7.
The highest number is 5.7.
The next lowest is 5.17 or 31/6.
The next lowest is 5.
The lowest is 4.9 or √24.
