Answer: 600 students
Step-by-step explanation:
Of the total number of sixth graders who were surveyed, 5% owned birds.
This 5% translated to 30 students.
30 students is therefore 5% of the total number of sixth graders surveyed.
Assume that number to be x:
x * 5% = 30
x = 30 / 5%
= 600 students
Answer:
$68,000
Step-by-step explanation:
we have to determine the total economic costs of going to college = ($40,000 x 2) + ($30,000 x 2) = $140,000
since we want to recover our "college investment" in 5 years or less, then we must earn at least $140,000 / 5 = $28,000 more per year
the minimum salary that we should earn after graduating = $40,000 (our current salary) + $28,000 (to recover college costs) = $68,000
A number reduced by a number larger would have a negative sum.
Example:
5 - 15 = -10
An easy way to solve equations like this is to subtract the smaller number from the larger number then add a negative sign to the sum.
Example:
5 - 15 would become 15 - 5
15 - 5 = 10
Just add a negative sign and that is the answer.
5 - 15 = -10
Now, to solve your equation, we would first reverse the order.
2 - 233
233 - 2 = 231
Lastly, add the negative sign.
231 would change to -231
Your answer would be -231.
I hope this helps!
Answer:
50 and 80
Step-by-step explanation:
two numbers are in ratio 5;8 which is 5x + 8x
sum = 130
5x + 8x = 130
13x = 130 ( divide both sides by 13)
x = 10
to find the two numbers we multiply by x
5x = 5 x 10 = 50
8x = 8 x 10 = 80
