Answer: 24%
Step-by-step explanation:
First add up the proportion of people who walk to work and those who bike as well. This will show the proportion of people who walk or bike to work.
This is:
= 5/25 + 1/25
= 6/25
Then convert this to a percentage:
= 6/25 * 100
= 24%
You can rewrite this as A - 25 = 75. You always can cancel adding a negative into just subtracting, and although it may not seem important yet, it’s a good habit to get into for further algebra.
A = 100.
Answer:
Step-by-step explanation:
Money spent on rent =1/3 of $576= 1/3×576= $192
Money spent on food = 1/4 of 576 = 1/4×576 =$144
Money left = 576-(192+144)=
=576-336= $240
Let x = the number.
"increased by" tells you we are adding.
"twice a number" tells you 2 times a number.
16 + 2x = - 24
Subtract 16 from both sides so that we have the variable on one sides and the constants on the other.
2x = - 24 - 16
2x = - 40
Divide by 2 to isolate the variable.
x = - 40/2 = - 20
Your solution is - 20.
To check your answer, plug in.
16 + 2(-20) = - 24
16 - 40 = - 24
- 24 = - 24
