Answer:
2x = 256
Step-by-step explanation:
Your problem → 82.5 + 8(0.25x) = 338.5
82.5+8(0.25x)=338.5
⇒-256+80.25x=0
⇒2x-256=0
⇒2x=256
⇒x=256/2
⇒x=128
Answer= 285000
How to= the number you are dividing by has a decimal move the decimal point all the way to the right counting the number of places you’ve moved it to. Then move the decimal point in the number you’re dividing the same number of places to the right
Answer:
here were 328 parts per million of carbon dioxide in the atmosphere in 1959.
there are 414 parts per million of carbon dioxide in the atmosphere in 2017.
the increase is 414 - 328 = 86 parts per million.
the ratio of the increase to the amount in 1959 is 86 / 328 = .262.
the percent increase is 100 times that and is equal to 26.2%.

x = 20
I am not sure if you wanted the answer. Sorry!
Step-by-step explanation:
Let's solve your equation step-by-step.
1/10 x + 5 = - 3x - 13 + 4x
Step 1: Simplify both sides of the equation.
1/10 x + 5 = - 3x - 13 + 4x
1/10 x + 5 = - 3x + - 13 + 4x
1/10 x + 5 = (<em>- 3x + 4x</em>) + (- 13)
1/10 x + 5 = <em>x</em> + - 13
1/10 x + 5 = x - 13
Step 2: Subtract x from both sides.
1/10 x + 5 - <em>x </em>= x - 13 - <em>x</em>
- 9/10 x + 5 = - 13
Step 3: Subtract 5 from both sides
- 9/10 x + 5 - <em>5</em> = - 13 - <em>5</em>
- 9/10 x = - 18
Step 4: Multiply both sides by 10/(- 9).
(<em>10/ - 9</em>) * (- 9/10 x) = (<em>01/ - 9</em>) * (- 18)
x = 20
Hope this helps!
