A School District transported 310 students and teachers to a zoo in buses and vans. Each bus transported a total of 20 students and teachers Each van transported a total of 10 students and teachers. There were 5 more buses than vans. What is the total number of students & teachers who rode the buses to the zoo? What is the total number of students & teachers who rode the vans to the zoo?
Answers
Answer:
240 Students and teachers rode buses
70 students and teachers rode vans
Step-by-step explanation:
Let the total number of buses be x
Let the total number of vans be y
If there were 5 more buses than vans, then x = y+5 ...... 1
If each bus transported a total of 20 students and teachers and each van transported a total of 10 students and teachers then:
20x + 10y = 310 ..... 2 (where 310 represents the total number of students and teachers in the school district)
Substitute equation 1 into 2:
20(y+5)+10y = 310
20y+100+10y = 310
30y = 310-100
30y = 210
y = 210/30
y = 7
Substitute y = 7 into equation 1 to get x:
From 1: x = y+5
x = 7+5
x = 12
The total number of buses are 12 while the total vans are 7
If each bus transported a total of 20 students and teachers, the total number of teachers and students that rode the buses to the zoo will be 20*12 = 240 teachers and students
If each van transported a total of 10 students and teachers, the total number of teachers and students that rode the vans to the zoo will be 10*7 = 70 teachers and students

Complete question :
Juan is rewriting the expression 12 d minus 26 c as a product. Which statements about the expression are accurate and relevant to his rewriting the expression? Select two options. The GCF of the numbers in each term in the expression is 2. The GCF of the numbers in each term in the expression is 4. The GCF of the variables in each term in the expression is cd. The factored expression is 2 (6 d minus 13 c). The factored expression is 2 c d (6 minus 13).
Answer:
The GCF of the numbers in each term in the expression is 2.
The factored expression is 2 (6 d minus 13 c).
Step-by-step explanation:
The two numbers being written are :
12d ; - 26c
Then greatest common factor of the Coefficients is :
Factors of
12 : 1, 2, 3, 4, 6, 12
26 : 1, 2, 13
Hence, the greatest common factor is 2.
Expressing 12d and - 26c as a product :
12d * - 26c
Factorizing :

The volume of a cube is given by the formula V=S3 Find the Volume when each side of the cube is 3 1/2 inches. Question 4 options: Blank # 1 Blank # 2 Blank # 3
Answers
Answer:
V = 343/8 cubic inches
Step-by-step explanation:
Here, we want to find the volume of the cube given the length of its side
Mathematically, the volume of a cube is L^3
where L represents the length of one of its side.
3 1/2 = 7/2 inches
Thus we have; 7/2 * 7/2 * 7/2 = 343/8 inches cube

Suraj took a slice of pizza from the freezer and put it in the oven. The oven heated the pizza at a rate of 7.5^\circ7.5 ∘ 7, point, 5, degrees Celsius per minute, and it reached the desired temperature of 80^\circ80 ∘ 80, degrees Celsius after 121212 minutes.
Answers
Answer:
y = 7.5t - 10
Step-by-step explanation:
A linear equation is in the form y = mx + b, where y is a dependent variable, x is an independent variable, m is the rate of change and b is the value of y when x = 0.
Let y represent the temperature of the pizza and t represent the time the pizza spent in the freezer in minutes. Therefore:
y = mt + b
Since the oven heats the pizza at a rate of 7.5°C, therefore
y = 7.5t + b (we need to find b)
It takes 12 minute (t = 12) to reach a temperature of 80°C (y = 80), hence:
80 = 7.5(12) + b
80 = 90 + b
b = -10
This means that the initial temperature of the pizza when removed from the freezer is -10°C. The linear equation is:
y = 7.5t - 10

–4(x – 26) = –200
x =
Answers
Answer:
x = 81
Step-by-step explanation:
With this equation, you would first want to multiply -4 to x and -26.
Your new equation is now -4x + 124 = -200
You would then subtract 124 from both sides leaving you with
-4x = -324
Finally, you would divide both sides by -4, leaving you with
x = 81

Answer:
6 (x + 3) + x = 7 x + 9 + 9
Step-by-step explanation:
The equation will have an infinite number of solutions if the left side is equal to the right side. The left side in each case is 7x+18.
The right sides are (in the order shown) ...
= 7x +3
= 7x +5
= 6x +18
= 7x +18 . . . . . . matches the left side
The equation 6 (x + 3) + x = 7 x + 9 + 9 will have infinitely many solutions.
