The state fair is a popular field trip destination. This year the senior class at High School A and
the senior class at High School B both planned trips there. The senior class at High School A
rented and filled 1 van and 3 buses with 80 students. High School B rented and filled 14 vans
and 1 bus with 218 students. Each van and each bus carried the same number of students. Find
the number of students in each van and in each bus.
Answers
Answer:
each bus carries 22 students
each van carries 14 students
Step-by-step explanation:
1v+3b=80
14v+b=218
eliminate b by multiplying the bottom equation by 3.
(42v+3b=654)-(1v+3b=80)=
41v=574
divide both sides by 41
v=14 (each van carries 14 students)
substitute the value of v into either of the og equations
1(14)-14+3b=80-14
3b=66
divide both sides by 3
b=22 (each bus carries 22 students)

Kadeem wants to ride his bicycle 52 miles this week. He has already ridden 16 miles. If he rides for 5 more days, write and solve an equation which can be used to determine xx, the average number of miles he would have to ride each day to meet his goal.
How to solve this for an equation.
Answers
The average number of miles that would be ridden to meet his goal is 7.2 miles.
Total distance = 52 miles
Distance ridden = 16 miles
Number of days left = 5 days
Let the number of miles that'll be ridden for each day be represented by x.
Therefore, the equation to solve the question will be:
5(x) + 16 = 52
5x + 16 = 52
5x = 52 - 16
5x = 36
x = 36/5
x = 7.2
Therefore, he'll have to ride 7.2 miles per day.

Mr Frasier worked her 40 regular hours last week, plus 4 overtime hours at the double time rate. Her gross pay was $734.40. What was her hourly rate?
Answers
Answer:
15.30 per hour
Step-by-step explanation:
The hourly rate for Mr Frasier will be $15.30.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Mr Frasier worked her 40 regular hours last week, plus 4 overtime hours at the double-time rate. Her gross pay was $734.40.
The hourly rate will be calculated as:-
Rate = 40 + 2 x 4 = 734.40
Rate = 40 + 8 = 734.40
Rate = 734.40 / 48
Rate = $15.3
The hourly rate is $15.3.

Consider the linear function f(x) = 3x-1. Find f(0), f(1), f(2)
Answers
Answer:
f(0) = -1, f(1) = 2, f(2) = 5.
Step-by-step explanation:
f(0) = 3(0) - 1 = -1
f(1) = 3(1) - 1 = 2
f(2) = 3(2) - 1 = 5
The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function is given below.
f(x) = 3x + 1
The value of the function at x = 0 will be
f(0) = 3(0) + 1
f(0) = 0 + 1
f(0) = 1
The value of the function at x = 1 will be
f(1) = 3(1) + 1
f(1) = 3 + 1
f(1) = 4
The value of the function at x = 2 will be
f(2) = 3(2) + 1
f(2) = 6 + 1
f(2) = 7
The value of the function f(x) = 3x + 1 at x = 0, 1, and 2 will be 1, 4, and 7, respectively.

m is the slopec is the y-intercept[ remember that a general line equation must be in slope - intercept form as shown above ]
• from our question, we are given the equation;

which inequality is true when the value of w is 13 w-<5 -w-3>-5 -w-3>5 w->5
Answers
w > -5 shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true
We need to get the equation that is true for w to be 13. This means that the required inequality expression should be w must be a positive integer.
For the Expression -w - 3 > -5
-w > -5 + 3
-w > -2
w < 2
Since w is less than 2, hence the inequality is wrong
For the inequality
-w - 3 > 5
-w > 5 + 8
-w > 13
w < -13
Since w < -13, hence the inequality is wrong
For the inequality w > -5
It shows that w is greater than -5 and since 13 is greater than -5, hence the inequality expression w > -5 is true
