To write an equation and simplify it, I'll start with this:
$4,500 = $90 + $39X Let X represent the amount of people attending the party.
Subtract 90 and both sides of the equation to make the $39X alone.
$4,410 = $39X
Divide $39 into both sides of the equation to isolate or bring X alone.
113.076923 = X
Now since we have to round down, we will do 113.
Answer: 113 people can attend the anniversary party.
Answer:
0.75 days (im a bit unsure but i tried my best, hope this helps :) )
Step-by-step explanation:
If it takes 8 technicians 36 hours to test 560 samples, find how many technicians can test 525 samples.
8: 560
x: 525
x= 7.5 (which is considered 7)
Then, find how long it takes to sample 525 samples, when 560 are done in 36 hours;
560: 36
525: x
x= 33.75 (which is considered 34 hours)
The last step is to check how long 15 technicians take to sample 525 samples when 8 can do the same number in 34 hours. this is inverse proportion so dont forget to flip one numerator and denominator
8; 34
15; x
it will become
15:34
8: x
x= 18 hours
Divide by 24 for days hence 0.75 days
If the ratio of red to blue pens is 3:1, we can find the amount of blue pens by multiplying by 1/3, to get 21*1/3=7. There are 21 red pens and 7 blue pens, so there are 21+7=28 pens total.
