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
3. Greg's family went to the movie theater and bought
tickets and popcorn. They spent $35 altogether with $9.50
spent on popcorn.
Write an equation that can be used to find out how much
money x they spent on tickets. (DO NOT use $ in your
equation, please.)
McGraw
Answer:
$25.50
Step-by-step explanation:
35 - 9.5 = x
25.5 = x
Answer:
Step-by-step explanation:
Let p=pop corn and x=tickets.
Because they have $9.50 on popcorn you should subtract 9.50 from 35. This gives you $25.50 dollars.
Because you know that they used the rest of the money to but tickets, they spent $25.50 on tickets
Therefore the equation should be 35-9.50=x or x=35-9.50

Find the missing angle.
86°
84•
?
36
Answer:
? = 64°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
The third angle in the triangle on the right is
third = 180° - (84 + 36)° = 180° - 120° = 60°
Thus the third angle in the triangle on the left is
third = 90° - 60° = 30° , then
? = 180° - (86 + 30)° = 180° - 116° = 64°

What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ΔABC
Let the second triangle be represented as ΔEAD
Now , the measure of side AC = 4.8
The measure of side BA = 3.1
And , the measure of side EA = 4.8
The measure of side DA = 3.1
And , Corresponding sides of similar triangles are in the same ratio
So , the triangles ΔABC and ΔEAD are similar
Therefore , the angles will also be congruent
The measure of ∠ACB = The measure of ∠DEA = x°
The measure of ∠DEA = 180° - ( 53° + 86° ) ( angles of a triangle = 180° )
On simplifying the equation , we get
The measure of ∠DEA = 41°
Hence , the measure of x = 41° and they are similar triangles
