The sum of the number in each of the four rows is the same The sum of the numbers in each of the three columns is the sameThe sum of any row does not equal the sum of any column[tex]\bold{\underline{ Let's \: Begin}}[/tex]
According to the Second rule :-
[tex]\sf{ 75+b+83=76+80+d=a+81+85+78+c+e }[/tex]
[tex]\sf{ 158 + b = 156 + d = 166 + a = 78 + c + e ...(1)}[/tex]
According to the first rule :-
[tex]\sf{ 75+76+a+78 = b+80+81+c = 83+86+d+e}[/tex]
[tex]\sf{ 229 + a = 161 + b + c = 168 + d + e ...(2)}[/tex]
From ( 1 ) we got :-
[tex]\sf{ 158 + b = 166 + a, 156 + d = 166 + a }[/tex]
[tex]\sf{ b = 166 - 158 + a, d = 166 - 156 + a }[/tex]
[tex]\sf{ b = 8 + a, d = 10 + a ...(3)}[/tex]
Subsitute (3) in ( 2 ) :-
[tex]\sf{229+a = 161+8+a+c = 168+10+a+e}[/tex]
[tex]\sf{ 229+a = 169+a+c = 178+a+e}[/tex]
We can write it as :-
[tex]\sf{ 229+a = 169+a+c \:or\:229+a = 178+a+e}[/tex]
[tex]\sf{ c = 299-169+a-a\:or\:e = 229-178+a-a}[/tex]
[tex]\sf{ c = 60 \: and \: e = 51 }[/tex]
Subsitute the value of c and e in ( 1 ):-
[tex]\sf{ 158 + b = 156 + d = 166 + a = 78 + 60 + 51 }[/tex]
[tex]\sf{ 158 + b = 156 + d = 166 + a = 189}[/tex]
Now,
[tex]\sf{ For \: b, 158 + b = 189 }[/tex]
[tex]\sf{ b = 189 - 158 }[/tex]
[tex]\sf{ b = 31}[/tex]
[tex]\sf{ For \: d , 156 + b = 189 }[/tex]
[tex]\sf{ d = 189 - 156 }[/tex]
[tex]\sf{ d = 33}[/tex]
[tex]\sf{ For \: a, 166 + a = 189 }[/tex]
[tex]\sf{ a = 189 - 166 }[/tex]
[tex]\sf{ a = 23 }[/tex]
Hence, The value of a, b, c, d and e is 23, 31 ,60 ,33 and 51 .

BRAINLIEST PLEASE !!! :)
8 meters is equivalent to the fraction 2/5 of 20 meters.
Given that:
Given part, 8 meters
And whole part, 20 meters
To express 8 meters as a fraction of 20 meters, simply divide the given part by the whole.
The formula is given below,
Fraction = (Part) / (Whole)
Put the given values in above formula and calculated as:
Fraction = (Part) / (Whole)
Fraction = 8 m / 20 m
Now, simplify the fraction by canceling out the common factor of 4:
Fraction = (8 m / 4) / (20 m / 4)
Fraction = 2 m / 5 m
So, 8 meters is equivalent to the fraction 2/5 of 20 meters.

Multiplication means add the indices.
Same denominators so add up the indices, 5^-3 x 5^6 –> -3 + 6 = 3

________
2^3 x 5^2
Divide means take the indices away.(Same base number only)
5^3 divided by 5^2 —> 3-2 = 1
5^1 = 5
2^2 divided by 2^3 —> 2-3 = -1
2^-1 = 1/2 or 0.5

Answer:
1. Point of intersection = (4, 360)
2. (4, 360) number of hours and the total cost of the repairs is the same for both repair shops
3. Amy's Auto Repair: $280
Step-by-step explanation:
1. y = 100 + 65x and y = 40 + 80x
Equate the equations and solve for x:
y = y ⇒ 100 + 65x = 40 + 80x
subtract 65x from both sides ⇒ 100 = 40 + 15x
subtract 40 from both sides ⇒ 60 = 15x
divide both sides by 15 ⇒ 4 = x
Therefore, x = 4
Substitute x = 4 into either of the equations to find y:
⇒ y = 40 + (80 x 4) = 40 + 320 = 360
Point of intersection = (4, 360)
2. The two lines intersect at (4, 360)
In this context, the point of intersection is where the number of hours and the total cost of the repairs is the same for both repair shops.
3. Substitute x = 3 into the equations and compare:
Mike's repair shop: y = 100 + (65 x 3) = 295
Amy's auto repair: y = 40 + (80 x 3) = 280
Therefore, Amy's Auto Repair is the cheapest (as 280 < 295) and the cost is $280.
