SUM:
If the numbers are the same sign, the sum will be the same sign as the numbers.
If they are different signs, the sum will be the same sign as the number with the largest size.

DIFFERENCE:
If the numbers are of different signs, the difference will be the same sign as the first number.
If the numbers are of the same sign, the difference will be the same sign as the numbers if the first number has the larger size, and the opposite sign to the numbers if the second number has the larger size.

How can I create a word problem with the following expressions <br><br> 15+2d<br><br> 200-4m
Alenkasestr [34]
For the first expression
15 + 2d
A possible word problem would be this:
A person saves $2 per day of money. Before he started saving, he had $15 dollars set aside. Look for the expression that expresses the total amount of money saved in terms of the number of days passed

The second expression is
200 - 2m
A possible word problem would be this:
The distance from school to the park is 200m. A kid riding a bike is traveling at a speed of 2m/s from the school to the park. Write an expression for the distance remaining between the park and the kid.<span />

the u.s department of agriculture reported that 57 out of every 100 milk drinkers drink skim milk. if a storeowner orders 24 gal
S_A_V [24]
STEP 1:
Find percentage. 57 out of 100 is the percentage to multiply by.

57/100= 0.57 (= 57%)

STEP 2:
Multiply percentage by the total gallons ordered (24).

=24 gallons * 0.57
=13.68 gallons


ALTERNATIVE METHOD (use which works best for you)

Set up a proportion. 57 to 100 is x out of 24 gallons.

x= number skim gallons to order

57/100= x/24
cross multiply
(57*24)= (100*x)
1368= 100x
divide both sides by 100
13.68 gallons= x

ANSWER: Since you cannot order a partial gallon of milk, round up to 14 whole gallons

Hope this helps! :)
