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?
Answers
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.

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.
Answers
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
2 x 3 x 4 = 24
8 x 3 x 4 = 96
(24 x 4 = 96)
If you think about it, you are essentially stacking four equal size boxes on top of each other, which combines is 4x the original box size.

Two angles are supplements if their sum is 180 degrees. The measurement of
one angle is five more than six times its supplement. What is the measurement of
the smaller angle?
Answers
180 = x + y
y = 6x + 5
180 = x + y
180 = x + (6x + 5)
180 = 7x + 5
175 = 7x
25 = x
180 = 25 + y
155 = y
the smaller angle (x) is 25 degrees.

Is 2(6 – 3x) + x equivalent to 2(3x) + x + 12?
Answers
Answer:
Step-by-step explanation:
Carry out indicated operations to see if they are equal
2(6-3x)+x=2(3x)+x+12
2(6)+2(-3x)+x=6x+x+12
12-6x+x=6x+x+12 combine like terms on both sides
12-5x=12+7x (we can see here they are unequal but we can continue) subtract 12 from both sides
-5x=7x divide both sides by x
-5=7
7 is not equal to -5 so the original expressions aren’t equivalent.

Sum of interior angles is 540°
x = 90°
m∠B = 90°
m∠E = 100°
Step-by-step explanation:
to find the sum of the interior angles you take the number of sides, deduct two, and multiply by 180
a 5-sided figure would be (n - 2)·180° = 3(180) = 540°
add together all five angle measures and set equal to 540; combine like terms and solve for 'x'
220 + 130 + 130 + x + x + 10 = 540
350 + 2x + 10 = 540
2x + 360 = 540
2x = 180
x = 90
