Answer:
11 years
Step-by-step explanation:
7200 - 80x = 5000 + 120x
-5000 + 80x -5000 + 80x
2200 = 200x
11 = x
The equation for this would be 4x+3=y where x is months and y is your amount of toys after x months.
plug in 4 for x -> 4(4)+3=y
solve -> 16+3=y
y=19
Answer:
3 1/3 metric tons per hour
Step-by-step explanation:
To find the unit rate, divide 3 3/4 metric tons by 1 1/8 hours (notice that the correct format is 3 3/4, not 3/3/4).
3 3/4 metric tons 3.75 metric tons
---------------------------- = --------------------------
1 1/8 hours 1.125 hours
It's easier to deal with decimal fractions here than with proper fractions.
The unit rate then comes out to be 3.75/1.125 metric tons per hour, or
3.33333 metric tons per hour, or 3 1/3 metric tons per hour
Answer:
2pi/3
Step-by-step explanation:
So we have to add the expenses and savings, and subtract them afterwards, lets call them negative and positive respectively to group them:
negative = tuition + room + book + personal
negative = 7800 + 6725 + 1200 + 2225
negative = 17950
positive = savings + grant + scolarship
positive = 5685 + 1500 + 3750
positive = 10935
we have to subtract the negative from the positive to have a grand total:
total = positive - negative = 10935 - 17950= -7015
that means that the savings, grant and scholarship are not enough to pay the total expenses, they lack $7015 indeed
