Answer: The value of x is 155/79.
Step-by-step explanation:
13(6x -5 )-x= 13 -2(x +1)
78x - 65- x = 13 -2x -2
77x -65 = 11-2x
79x -65 =11
79x =76
x = 76/79 76/ 79 + 1/1 = 155/79
Answer:
3,717,000
Step-by-step explanation:
The calculation of paperback copies is shown below:-
Let us assume hardback copies is x, so paperback copies will be 9x
now the equation is
35,000 + x + 9x = 448,000
10x = 448,000 - 35,000
10x = 413,000

= 41,300
Therefore, the paperback copies are
= 
= 3,717,000
Hence, the paperback copies is 3,717,000
Answer:
Step-by-step explanation:
Given
Total area of two plot 
Let l and b the length and width of plot
Perimeter for Fencing




Put value of b in 1




so there can be two value of l i.e. 
for
Answer:
eric=12
bill=16
Step-by-step explanation:
you can solve this using two simple algebraic equations. this is the key I will be using:
x=bill
y=Eric
x+y=28
x=y+4
since x is by itself in the second equation, I can replace the x in the first equation with y+4
(y+4)+y=28
subtract 4 from both sides
y+y=24
which is also 2y=24
divide both sides by two.
y=12
so now we know Eric is 12 years old.
using this, we can replace the "y" in the second original equation (x=y+4)
x=12+4
x=16
Bill is 16 years old.
Answer:
The answer: 53x+13x=1313+83x
Step 1: Simplify both sides of the equation.
53x+13x=1313+83x
(53x+13x)=83x+1313(Combine Like Terms)
2x=83x+1313
2x=83x+1313
Step 2: Subtract 8/3x from both sides.
2x−83x=83x+1313−83x
−23x=1313
Step 3: Multiply both sides by 3/(-2).
(3−2)*(−23x)=(3−2)*(1313)
x=−1312
Answer:
x=−131/2
