I'll explain you number one
3
Step-by-step explanation:
You first subtract the single number (1) subtract to 10 which gives you 9, then you will divide 3 from 9 which gives you 3
Sorry I couldn't help you with there other ones.
5s + 10 = 200
You need to get rid of 10 first, you do this by subtracting it by 10, you also subtract 10 to 200
5s = 190
Now you need to get rid of 5 that is attached to the variable, you must divide 5 since it is multiplying, also dividing 5 to 190
s = 38
So it would be 38 sponsors
Comic books:
4c + 6 ≤ 20
Take away 6 by subtracting, also subtracting 6 to 20
4c ≤ 14
You then have to divide 4 to the variable, also dividing 4 to 14
c ≤ 3.5
Now since you can’t get half of a comic book, the greatest amount of comic books he can buy is 3.
3 comic books
Value of x:
3x + 1 = 10
Take away 1 by subtracting 1, also subtracting 1 to 10
3x = 9
Divide 3 to the variable, dividing 3 to 9 as well
x = 3
Value of y:
4y + 6 ≥ 18
Subtract 6 to 6 and 18
4y ≥ 12
Divide 4 to both sides
y ≥ 3 or y is greater than or equal to 3 (in case you can’t see the symbol)

Answer: 1,000 x 20,000 = 20,000,000
1,200 x 15,000 = 18,000,000
20,000,000 - 18,000,000 = 2,000,000
$1000 divided by $20000 is 0.05 which is 5%
$1200 divided by $15000 is 0.08 which is 8%
So julissa has a commission rate of 5% and destiny has a commission rate of 8%
So the difference is 3%

The mean monthly rainfall is 3.245 inches.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Given is a table which shows the monthly rainfall at a measuring station.
Mean of a set of data = Sum of the data vales / Total number of values.
Here,
Total number of data points = 12
Sum of the data points = 2.22 + 1.51 + 1.86 + 2.06 + 3.48 + 4.57 + 3.27 + 5.40 + 5.45 + 4.34 + 2.64 + 2.14
