Answer:
x=6/7
Step-by-step explanation:
7x÷2+5=8
divide by 2 on both sides:
7x/2+5=8(it's a fraction)
subtract 5 on both sides
7x÷2=3
multiply 2 on both sides
7x=6
divide by seven on both sides
x=6/7

Answer:
C). 54 cm.
Step-by-step explanation:
I think you mean a rectangle .
If the length is x then the width = 0.75x (because 3/4 = 0.75).
Perimeter = 2*length + 2*width.
252 = 2x + 2*0.75x
252 = 2x + 1.5x
252 = 3.5x
x = 252 / 3.5
= 72 which is the length,
The width = 3/4 * 72
= 54 cm.
The equation is 1/2+3/x=3/4, it is still solvable
the equivalent of the equation is (1.x+2.3)/2.x = 3/4, or (x+ 6)/2.x=3/4, this last can be solved as follow: 4.(x+ 6) = 2x.3, 4x+ 24 = 6x, so 24=6x-4x=2x, and when 2x= 24 , it means x=24/2 =12, finally the equation is solvable because x=12 is a solution
8/10 but if u simplify it its 0.8
Answer:
71
Step-by-step explanation:
Evaluate for x=12
(8)(12)−25
(8)(12)−25
=71
