Answer:
each van carries 7 students
each bus carries 60 students
Step-by-step explanation:
let v = # students in a van
let b = # students in a bus
system of equations:
13v + 2b = 211
4v + 4b = 268
I multiplied the 1st equation by -2 to eliminate the 'b' terms
-26v - 4b = -422
+ 4v + 4b = 268
-22v = -154
v = 7
substitute '7' for 'v':
4(7) + 4b = 268
28 + 4b = 268
4b = 240
b = 60
Answer:
13v + 2b = 211
4v + 4b = 268
#students each VAN can carry: 7
#students each BUS can carry: 60
Step-by-step explanation:
Let v = number of students in each van.
Let b = number of students in each bus.
High School A:
13v + 2b = 211
High School B:
4v + 4b = 268
The system of equations is
13v + 2b = 211
4v + 4b = 268
We will solve this system of equation with the addition method.
Write the first equation as it is. Divide both sides of the first equation by 2 and write it below the first equation. Then add the equations.
13v + 2b = 211
(+) -2v - 2b = -134
----------------------------
11v = 77
Divide both sides by 11.
v = 7
Substitute 7 for v in the first original equation and solve for b.
13v + 2b = 211
13(7) + 2b = 211
91 + 2b = 211
Subtract 91 from both sides.
2b = 120
Divide both sides by 2.
b = 60
Answer:
13v + 2b = 211
4v + 4b = 268
#students each VAN can carry: 7
#students each BUS can carry: 60

Which measurement is closest to the area of the circle in square centimeters ? A. 31.4cm² B. 78.5cm² C.62.8² D.50.2cm²
Answer: it’s a
Step-by-step explanation: took the test got it right
The required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.
What is an area circle?The area of the circle is given by the pie times square of the radius.
Area of circle = πr^2
Here,
Let the radius of the given circle be r = 5 cm
Area of the circle = πr²
Substitute the value in the above expression,
Area of the circle = π 5²
Area of the circle = 78.5cm²
Thus, the required measurement closest to the area of the circle in square centimeters is 78.5cm². Option B is correct.

Elaina charged $83 on her credit card to buy groceries. If the
balance is now $294, what was the balance before she bought
groceries?
Answer:
211?
Step-by-step explanation:
I'm not sure if this is correct, but:
294-83=211.
Hope this helps! :)
The balance before she bought the groceries was $277.
What are mathematical operations?In mathematics, an operation is a function which takes zero or more input values (also called "operands" or "arguments") to a well-defined output value.There are five fundamental operations in mathematics: addition, subtraction, multiplication, division, and modular formsGiven is that Elaina charged $83 on her credit card to buy groceries. The balance is now $294.
The balance before she bought the groceries is -
294 + 83
277
Therefore, the balance before she bought the groceries was $277.

Jason has 1/3 of a liter of milk. Jason divides the milk equally into 4 mugs of tea.
How much milk will Jason have in each mug?
Answer:
1/12 l
Step-by-step explanation:
Amount of milk = 1/ 3 l
No: of mugs = 4
Amount in each mug = 1/3 ÷ 4 = 1/3 x 1/4 = 1/12 l
(Hope its right!)
Answer:
They will have 1/12 of a liter of milk on each mug because you are dividing 1/3 into 4 so the denominator is multiplied by 4

14=s/3 what does s equal
===============================================
Explanation:
To isolate s, we need to undo the division. We'll multiply both sides by 3
14 = s/3
3*14 = 3*(s/3)
42 = s
s = 42
-------
As a check,
14 = s/3
14 = 42/3 .... replace s with 42
14 = 14
We get the same thing on both sides, so this confirms we have the correct value of s.

Basil has five numbered cards.
Two of the numbers are hidden. 4 9 9 ? ? 8
The mode of the five numbers is 8.
The mean of the five numbers is 6
c) Work out the two hidden numbers.
Answer:
The two hidden numbers are 8 and 1.
Step-by-step explanation:
Mean of a data-set:
The mean of a data-set is given by the sum of all its values divided by the number of values.
Mode of a data-set:
The mode of a data-set is the value that appears the most.
In this question:
4, 9, x, y, 8
Mode is 8 means that at least one of them must be 8, so i will say x is 8 and we have:
4, 9, 8, y, 8
The mean of the five numbers is 6
This means that:
[tex]\frac{4+9+8+y+8}{5} = 6[/tex]
[tex]29+y = 30[/tex]
[tex]y = 30 - 29[/tex]
[tex]y = 1[/tex]
The two hidden numbers are 8 and 1.

Arithemetric sequence 4,16,28,40,52
Answer:
-8 + 12n
Step-by-step explanation:
First term = a = 4
Common difference = d = second term - first term
= 16 - 4
= 12
Nth term = a + (n -1) *d
= 4 + (n - 1)*12
= 4 + n*12 - 1*12
= 4 + 12n - 12
= 4 - 12 + 12n
= -8 + 12n
