Bao is taking a multiple choice test with a total of 100 points available. Each question
is worth exactly 2 points. What would be Bao's test score (out of 100) if she got 8
questions wrong? What would be her score if she got x questions wrong?
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.

Answer:
x = -1/2 or x = -3
Step-by-step explanation:
2x^2 + 7x + 3 = 0
First, we try factoring the polynomial.
(2x + 1)(x + 3) = 0
It works. Now we set each factor equal to zero.
2x + 1 = 0 or x + 3 = 0
2x = -1 or x = -3
x = -1/2 or x = -3

and
The mean is 24.5
To find the median just find the number in the middle of an odd set

To find the Mean add all of the numbers and divide them by the number of sets ( in this instance its 4 )
anyone please write an easy solution to solve this linear equation with brackets:
16-4(x+3)=2x
anyone pls explain i keep getting 7/2!!
Answer:
[tex] \large \boxed{x = \frac{2}{3} }[/tex]
Step-by-step explanation:
Goal
Solve the equation for x-term.Given
Equation[tex] \large{16 - 4(x + 3) = 2x}[/tex]
Step 1
Distribute/Expand 4 in the expression.[tex]16 - 4x - 12 = 2x[/tex]
Step 2
Isolate x and combine like terms.[tex]16 - 12 = 2x + 4x[/tex]
Step 3
Solve the equation for x-term[tex]4 = 6x \\ \frac{4}{6} = x \\ \frac{2}{3} = x[/tex]
Step 4
If you are not sure that the answer is correct, I suggest to check the answer by substituting the value of x in the equation.[tex]16 - 4x - 12 = 2x[/tex]
Substitute x = 2/3 in the equation.
[tex]16 - 4( \frac{2}{3} ) - 12 = 2 (\frac{2}{3} ) \\ 4 -4( \frac{2}{3} ) = 2( \frac{2}{3} )[/tex]
Evaluate
[tex]4 - \frac{8}{3} = \frac{4}{3} [/tex]
Move -8/3 to add with 4/3.
[tex]4 = \frac{4}{3} + \frac{8}{3} \\ 4 = \frac{12}{3} \\ 4 = 4[/tex]
The equation is true for x = 2/3. Hence, the solution is x = 2/3.
Hope this helps! Any questions about the answer can be asked in comments.

Xin answered 182 questions correctly on her multiple choice math final that had a
total of 200 problems. What percentage of questions did Xin answer correctly on the
final exam?
Answer:
91%
Step-by-step explanation:
182/200 = .91
.91 = 91%
Hope that helps!
The percentage of questions Xin answered correctly on the final exam is 91% if he answered the number of 182 questions correctly on her multiple choice.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
We have:
Total number of problems = 200
Total number of Xin answered correctly = 182
Then the percentage of questions XIn answers correctly:
[tex]= \frac{182}{200} \times100[/tex]
= 0.91×100
= 91 %
Thus, the percentage of questions Xin answered correctly on the final exam is 91% if he answered the number of 182 questions correctly on her multiple choice.

A bakery sells oatmeal raisin cookies for $3 per bag. In the table below b
represents teh number of bags and c represents the cocst in dolloars.
Complete the function table using the rule c = 3b
Answer/Step-by-step explanation:
Number of bags = b
Cost in dollars = c
Unit price of raisin = $3
We have the function given as c = 3b.
To complete the table, substitute each value of b into c = 3b, to find the corresponding value of c.
✔️when b = 1,
c = 3(1)
c = 3
✔️when b = 2,
c = 3(2)
c = 6
✔️when b = 3,
c = 3(3)
c = 9
✔️when b = 4,
c = 3(4)
c = 12

Given QUAD is a quadrilateral,
find the value of x.
If the answer is 14, move to J
If the answer is 30, move to L
If the answer is 23, move to K
If the answer is 21.4, move to M
Answer:
=>(4x+14)+(5x-1)+(4x-5)+(2x+7) = 360°
=>4x + 14 + 5x - 1 + 4x - 5 + 2x +7 = 360°
=>15x + 15° = 360°
=>15x = 360°- 15°
=>x = 345/15
=>x = 23
So move to K

Answer:
Area of the sector = 78.54 square meters
Step-by-step explanation:
Radius of the given circle = 10 meters
Sector bounded by the arc having measure = 90°
Angle subtended by the arc at the center = 90°
Area of the sector = [tex]\frac{\theta}{360}(\pi r^{2})[/tex]
Here angle θ is the angle at the center subtended by the arc.
If angle θ = 90°
Therefore, area of the sector = [tex]\frac{90}{360}(\pi)(10)^{2}[/tex]
= 25π
= 78.54 square meters

is -5(x+8) equal to -5x-40 pleaseeee i need helppp
Answer:
yes
Step-by-step explanation:
The distributive property of multiplication over additions is:
a(b + c) = ab + ac
You multiply the number outside the parentheses, the a, by each of the numbers inside the parentheses, the b and the c. Then you add the products.
Now we can do it with your example.
-5(x + 8)
We multiply -5 by x and multiply -5 by 8. Then we add the products and simplify.
-5(x + 8) = -5 * x + (-5) * 8 = -5x + (-40) = -5x - 40
Answer: yes
Write the slope intercept equation for line AB
Answer:
