9x+1 = 2x+15
Subtract 1 from both sides.
9x=2x+14
Subtract 2x from both sides.
7x=+14
Divide 7 on both sides.
x=2
67+52+x=180
119+x=180
x=61
hope this helps!
the equation to be used would be x=180-(67+52)
Answer:
Step-by-step explanation:
We need to find the error first.
We can do this by subtracting, to find the difference
2.4-1.9 = 0.5
the difference, or error, is 0.5
Now we find a percentage that describes how much more 2.4 is than 1.9
We can create an equation to solve this
2.4 = 1.9 Times x
Now we need to find the value of x
x= 1.2632
now we double check
1.9 Times 1.2632 = 2.4
Now we round to a whole number
1.2632 = 1
To convert a number to a percentage, you need to bring the number over a decimal point.
so 1 becomes .1, or 10 percent
