Answer: In the last steps, instead of multiply each side by 3, he has to divide each side by 3.
Step-by-step explanation:
Hi, Tobin makes the mistake in the last steps.
3(x-1.25) = 11.25
3x-3.75= 11.25
3x-3.75+3.75= 11.25+3.75
3x = 15
Until this step is the work ok.
Now, instead of multiply each side by 3, he has to divide each side by 3:
So:
3x /3 = 15/3
x = 5

Answer:
that is the ten thousands place
Step-by-step explanation:
To determine the percent volunteers that worked in the intervals mentioned, you will need to create a ratio of the number of volunteers who worked in those 2 bars to the total number of volunteers in all the bars. The number in those 2 intervals are 4+5=9, The total number of volunteer represented in the histogram is 20. This creates a fraction 9/20. TO convert this to a percent, you can create an equivalent fraction with a denominator of 100 by multiplying by 5. This means the 9 is also multiplied by 5 to make 45/100. This is equivalent to 45%. You can also divide 9 and 20 to get 0.45 (45%).
