Answer:
84
Step-by-step explanation:
100-point test = 50 questions which are worth 2-points each.
(50 x 2 = 100)
If she got 8 wrong, this means she lost 16 points ( 8 questions x 2 points each = 16 points in total)
100 - 16 = 84
To find her score if she got x questions wrong just multiply x by 2 and subtract the answer to 100.
what is the proportion of 3 over 7 = n over 28
Answer:

what is the sum 0 of 62
Solve for x in the diagram below.
x
2x
(x+10)
The angles x°, 2x°, and (x + 10)° are complementary angles. Then the value of the variable x will be 20°.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
The angles x°, 2x°, and (x + 10)° are complementary angles.
Then the sum of the angles x°, 2x°, and (x + 10)° will be 90°.
Then the equation will be
x° + 2x° + (x + 10)° = 90°
Simplify the equation, then the value of x will be
4x + 10 = 90
4x = 80
x = 20°
Thus, the value of the variable x will be 20°.

what type of function is y=3x-2
Step-by-step explanation:
Explanation: y=3x+2 is not a function. Rather, it is just a regular linear equation.
It's not.
Explanation:
y=3x+2
is not a function. Rather, it is just a regular linear equation. However,
f(x)=3x+2
is a function, because it contains "
f(x)."
So, in general, if it contains " y ," then you are safe in assuming that it is an equation. If it contains "
f(x) ," then you are safe in assuming that it is a function.
I hope that helps!
The function y = 3x - 2 is a linear function.
Given data:
The function is represented as y = f ( x )
The value of y = 3x - 2
The equation y = 3x - 2 represents a linear function.
The function has a constant rate of change, which is 3, as the coefficient of x. The function forms a straight line when graphed on a Cartesian coordinate plane.
The term "linear" indicates that the relationship between x and y is of the first degree, meaning there are no exponents or other nonlinear components involved.

An angle measures 38° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
One angle is 26 degrees and the other is 64 degrees.
Step-by-step explanation:
Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:
90 = (x-38) + (x)
52 = 2x
26 = x
This means that one of the angles is 26 degrees, and the other is 64 degrees.

Write a System of Equations to solve the following problem:
The school that Maria goes to is selling tickets to the annual talent show. On the first day of ticket sales the school sold 1 senior citizen ticket and 12 student tickets for a total of $51. The school took in $93 on the second day by selling 5 senior citizen tickets and 6 student tickets. What is the price each of one senior citizen ticket and one student ticket?
Cost of Senior Citizen Ticket: $
Cost of Student Ticket: $
Answer:
Cost of Senior Citizen Ticket: $15
Cost of Student Ticket: $3
Step-by-step explanation:
Let the price of a senior citizen ticket be s.
Let the price of a student ticket be t.
Day 1:
s + 12t = 51
Day 2:
5s + 6t = 93
The system of equations is:
s + 12t = 51
5s + 6t = 93
Let's use the substitution method to solve it. Solve the first equation for s.
s = 51 - 12t
Now substitute s in the second equation with 51 - 12t.
5s + 6t = 93
5(51 - 12t) + 6t = 93
255 - 60t + 6t = 93
Subtract 255 from both sides. Combine -60t and 6t.
-54t = -162
Divide both sides by -54.
t = 3
Now substitute 3 for t in the equation
s = 51 - 12t
s = 51 - 12(3)
s = 51 - 36
s = 15
Answer:
Cost of Senior Citizen Ticket: $15
Cost of Student Ticket: $3

Answer:
20 is the anwser for this problem
The number of medium bags will be 410 / 3.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that Jill puts 440 sweets into small bags, medium bags and large bags. She uses 30 small bags
The equation can be written as,
L + M + S = 440
L = 2M
2M + M + 30 = 440
3M = 410
M = 410 / 3
Therefore, the number of medium bags will be 410 / 3.

In triangle ABC, A is a right angle and M B=45°. Find BC. If you answer is not an integer, leave it in simplest radical form.
Step-by-step explanation:
- In a right triangle, if ∠B is 45°, then ∠C is too.
-- Since ∠B and ∠C are equal, the sides opposite them
are equal too. This is an isosceles right triangle. Its legs
are equal.
-- (The hypotenuse)² = (one leg)² + (the other leg)²
= (12-ft)² + (12-ft)²
= (144 x 2)
The hypotenuse = √(144 x 2) = 12√2 .
