[x-1]=5x+10
We have two equations:
1) x-1=5x+10
x-1=5x+10
x-5x=10+1
-4x=11
x=-11/4
2) x-1=-(5x+10)
x-1=-(5x+10)
x-1=-5x-10
x+5x=-10+1
6x=-9
x=-9/6=-3/2
we have two possible solutions:
solution₁; x=-11/4
solution₂: x=-3/2
we check it out:
1) x=-11/4
[x-1]=5x+10
[-11/4 - 1]=5(-11/4)+10
[(-11-4)/4]=-55/4 + 10
[-15/4]=(-55+40) /4
15/4≠-15/4 This solution don´t work.
2) x=-3/2
[x-1]=5x+10
[-3/2 - 1]=5(-3/2)+10
[(-3-2)/2]=-15/2 + 10
[-5/2]=(-15+20)/2
5/2=5/2; this solution works.
Therefore:
Answer: x=-3/2.
Answer:
89 dollars
Step-by-step explanation:
47 and 53 cents make one dollar together. 12 dollars and 76 dollars make 88 dollars. 1+88=89
Answer: 48
Step-by-step explanation:
60 as a fraction= 60/1
We are going to multiply 60/1x4/5=240/5
The we are going to divide 240/5 and 5/5+ 48/1
and 48/1 is equal to 48
Answer:
Hi, There!
Option B 125% Is the Most Accurate Answer
Step-by-step explanation:
Circumference is the distance around a plane shape. So, it also measures length.
Length and area of two similar shapes are related by the formula
Where the A in both cases represents area and the L represents length. But here the Ls will represent circumference.
Since the circumference of the circle increased by 50%, then the new circumference becomes
Now subtracting from the original area then
This means that the area was increased by 1.25, which means 125%
Hence option B is the correct answer
I looked it up on google it is 1252
