3) When Jackie took her children to the movie theater, she bought one box of candy and three small drinks for
$14.75. When Alex went to the same theater and bought two boxes of candy and five small drinks, he paid
$26.
a) Set up a system of equations to model this situation. Be sure to define the variables that you use.
b) Determine, algebraically, the cost for one box of candy and one small drink
Answer:
c + 3d = 14.75
2c + 5d = 26
A box of candy is $4.25 and a drink is $3.50
Step-by-step explanation:
Let c represent the cost of a box of candy and let d represent the cost of a drink
c + 3d = 14.75
2c + 5d = 26
Solve by elimination by multiplying the top equation by -2
-2c - 6d = -29.5
2c + 5d = 26
Add them together
-d = -3.5
d = 3.5
Plug in 3.5 as d into one of the equations to solve for c
c + 3d = 14.75
c + 3(3.5) = 14.75
c + 10.5 = 14.75
c = 4.25
So, a box of candy is $4.25 and a drink is $3.50

One of the teachers at a school is chosen at random. The probability that this teacher is female is 3/5 There are 36 male teachers at the school. Work out the total number of teachers at the school.
Answer:
90 total teachers
Step-by-step explanation:
The total number of teachers at the school is 90 whereas there are 36 female and 54 male teachers.
Probability-based problem:What information do we have?
Probability teacher is female = 3/5
Number of male teachers = 36
Probability teacher is male = 1 - (3/5)
Probability teacher is male = 2/5
Total number of teacher = (5/2)(36) Total number of teacher = (5)(18)Total number of teacher = 90 teachers
the total number of teachers in the school is 90 teachers.

A university has 40,140 students. In a random sample of 210 students, 14 speak three or more languages. Predict the number of students at the university who speak three or more languages.
Answer:
2676 students
Step-by-step explanation:
Total number of students =. 40,140
During study:
Sample size = 210
Number of samples who speak 3 or more languages = 14
Proportion who speak 3 or more languages :
14 / 210 = 0.0666666
Applying the proportion to the total. Population :
0.0666666 * total number of students
0.0666666 * 40140
= 2675.997324
= approximately 2676 students

How many t-shirts could be made where the cost would be the same from both companies?
A system of equations is shown on the graph below.
On a coordinate plane, 2 lines intersect at (negative 1, 2).
How many solutions does this system have?
no solutions
one unique solution
two solutions
an infinite number of solutions
Answer: One unique solution.
Step-by-step explanation:
When we have a system of linear equations like:
y = a*x + b
y = c*x + d
We have 3 possibilities:
1) There is only one solution, this happens when in the graph, the lines intersect at only one point.
2) There is no solution, in this case, the lines never intersect, this would be the case of two parallel lines.
3) We have an infinite number of solutions, this happens when both lines intersect in an infinite number of points, and this can only happen when both lines are the same line.
In this case, we know that we have two lines and they intersect in only one point, (-1, 2)
Then we have only one solution, and the solution is (-1, 2)

Systems of equations by substitution
Answer:
(-2,1)
Step-by-step explanation:
Substitute the value of y (x+3) from one equation into the second equation (2x+5)
X+3 = 2x + 5
add -2x to both sides
-x+3=5
add -3 to both sides
-x=2
x=-2
substitute -2 for x in either equation to find y.
y=-2+3
y=1
Check your answer by substituting x and y into either equat to make sure it equals.
y=x+3
1=-2+3
1=1
or
y=2x+5
1=2(-2)+5
1=-4+5

A diameter is a chord.
True or false and why?
Answer:
true.
A chord that passes through the center of a circle is called a diameter and is the longest chord.
Step-by-step explanation:
A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.

What are the values of T and U?
Answer:
u+133°=180
u=180-133
u=47°
Answer:
U = 47
T = 86
Step-by-step explanation:
133 + U = 180 ( straight line)
or, U = 180 - 133
or, U = 47
Being isosceles triangle
47 + 47 +T = 180
or, 94 + T = 180
or, T = 180 - 94
