3 ÷ 2
Answer:
7 divided by 2

4. Tim bought 4 new baseball cards to add to his collection. The next day his dog ate half of his collection. There are now only 43 cards left. How many did Tim start with?
Answer: 1. 33 , 2. 21 , 3. $5.00 , 4. 39.
Step-by-step explanation:
4. Let the original number of baseball trading cards in Tim's possession be

Multiply both sides by

A store manager combines 2 lb of trail mix that contains some cashew nuts with 30 lb
of trail mix that is 20% cashews. The result is a trail mix that is 25% cashews. What is the concentration of cashews in the first mixture?
Answer:
100%
Step-by-step explanation:
Let p = percent of cashews in first mix
2p = lb. of cashews in first mix
30(.20) = 6 = lb. of cashews in second mix
32(.25) = 8 = lb. of cashews in the combined mix
So,
lb. of cashews in first mix + lb. of cashews in second mix = lb. of cashews in the combined mix
2p + 6 = 8
2p = 2
p = 1 = 100%
Answer:
100%

HELP ASAP WILL GIVE 30 points. A toy box measures 4 ft by 3 ft by 2 ft. Explain whether increasing
the height by four times, from 2 ft to 8 ft, would increase the volume
by four times.
Answer:
yes, the volume would be increased by 4
Step-by-step explanation:
the volume for a box is l x w x h
lets say l = 4, w = 3, and h = 2
this would give us a volume of 24
now calculate the new volume: l x w x 4h
4 x 3 x (4 x 2) = 96 which is 4 times bigger than 24

Answer:
yes, the point (-1, 5) is in the solution set
Step-by-step explanation:
y ≥ 2x + 3
Is 5 ≥ 2(-1) + 3? Yes
y + x > 0
Is 5 + (-1) > 0? Yes
Answer:
Yes the Point (-1,5) is in the solution set.
Step-by-step explanation:
Well you have to sub in the x and the y.
In the first equation
5 >= 2(-1) +3 = 5>= 1 So this one is true and in the set.
The second one
5+-1>0 = 4>0. So this one is also true.

Answer:
x = 13
Step-by-step explanation:
∠ EGB = ∠ AGF = 77° ( vertically opposite angles )
AB is a straight line so the 3 angles on it sum to 180° , that is
90 + x + 77 = 180
x + 167 = 180 ( subtract 167 from both sides )
x = 13

A class of 195 students went on a field trip. They took 19 vehicles, some cars and some buses. If each car
holds 5 students and each bus hold 25 students, how many buses did they take?
Answer:
Number of cars = 14
Number of buses = 5
Step-by-step explanation:
Let
x = number of cars
y = number of buses
x + y = 19 (1)
5x + 25y = 195 (2)
From (1)
x = 19 - y
Substitute x = 19 - y into (2)
5x + 25y = 195
5(19 - y) + 25y = 195
95 - 5y + 25y = 195
- 5y + 25y = 195 - 95
20y = 100
y = 100/20
y = 5
Substitute y = 5 into (1)
x + y = 19
x + 5 = 19
x = 19 - 5
x = 14
Number of cars = 14
Number of buses = 5
Based on the number of vehicles and the number that each vehicle can take, the number of buses required is 4 buses.
There are 19 vehicles which take 5 students each. This means that the number of kids entering buses will be:
= 19 x 5
= 95 students
The students entering buses will be:
= Total number of students - Kids in vehicles
= 195 - 95
= 100 students
If each bus takes 25 students, the number of buses required is:
= 100 students / 25
= 4 buses
In conclusion, 4 buses were taken.
