Answer:
3 buses are needed.
Step-by-step explanation:
If there are only 2 buses, it would be full, but there would still be 12 students without a bus. To take all students, you'd need 3 buses. 2 buses will be full, and the other bus would only have 12 students.
Answer:3 buses
Step-by-step explanation:
Because 50+50 is 100 which is two buses
But there are 12 students left so you need 1 more buses
70(h + 2)
70(h - 2)
70h
Answer:
After 7.8 hours (7 hours 48 min.) will the bus and car be 800 miles apart
70(h-2) expression represents the number of miles the car travels.
Step-by-step explanation:
If h represents the number of hours the bus travels.
In the question it is said that the bus leaves 2 hours before the car does
Therefore car travels (Time) = ( h-2 )
car's speed = 70 mph,
Distance = speed × time = 70(h-2)
70(h - 2) expression represents the number of miles the car travels.
If we want to find the number of hours will the bus and car be 800 miles apart we can solve it as :
50h + 70(h-2) = 800
50h + 70h - 140 = 800
120h = 800 + 140
120h = 940
h = 940 ÷ 120 = 7.833... = 7.8 hours (7 hours and 48 min.)
Ans. After the bus left the city, after 7.8 hours the car and the bus will be 800 miles apart.
The total number of bulbs in each bag will be 100.
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the middle-school camera club sold 240 tulip bulbs and 360 daffodil bulbs. Students divided the bulbs into 100 bags to sell at the school fair.
There will be 600 bulbs in all, so that would make 6 in each of the one hundred n
There will be 600 bulbs in all, therefore 6 in each of the 100 bags. An expression could be,
600=100x
Therefore, the total number of bulbs in each bag will be 100.
