Joshua took a math contest with 25 questions. Each correct answer earned 6 points while each incorrect answer deducted 4 points. Joshua answered every question and earned 100 points. How many questions did Joshua answer correctly?
Answer: 20 questions
Step-by-step explanation: 6x - (25 - x)*4 = 100
Answer: 20 correct, 5 incorrect
Step-by-step explanation:
25 question total
Create an equation: 6x(correct) - 4y(incorrect) = 100 (points)
You can guess and check if its easiest for you: 6(20) - 4(5) = 100 points
Check: 120 - 20 = 100 points
100 = 100

3. Write the equation of the line that passes through the point (-4,5) and has a slope of 1/4
Answer:
The equation of the line that passes through the point (-4,5) and has a slope of 1/4 is: [tex]y = \frac{1}{4}x+6[/tex]
Step-by-step explanation:
Given information is:
(x,y) = (-4,5)
Slope = m = 1/4
The slope-intercept form of equation of a line is given by the formula:
[tex]y = mx+b[/tex]
Here
m is the slope of the line and b is the y-intercept.
Putting the value of slope in the equation
[tex]y = \frac{1}{4}x+b[/tex]
Now to find the y-intercept we will put the point in the equation
[tex]5 = \frac{1}{4}(-4) + b\\5 = -1+b\\b = 5+1\\b = 6[/tex]
The equation of line is:
[tex]y = \frac{1}{4}x+6[/tex]
Hence,
The equation of the line that passes through the point (-4,5) and has a slope of 1/4 is: [tex]y = \frac{1}{4}x+6[/tex]
Solve for x.

Step-by-step explanation:
For every dollar Bennett spent on bagels, Dominic spent 25 cents less. Bennett
paid $12.50 more than Dominic. How much did they spend in the bagel store together?
(A) $37.50 (B) $50.00 (C) $87.50 (D) $90.00
(E) $92.50
Answer:
The answer is C:$87.50
Step-by-step explanation:
Ben - 1$
David - 0.75$
For each Bagel, Ben paid 0.25$ extra.
Then the total bagel Ben bought = 12.5/0.25 = 50 and the money spent = 50$
Then david spent = 3/4*50 = 37.5$
Total = 50+37.5 =$87.50
Which of the b-values satisfy the following inequality? 5 < b-3
a. b=8
b. b=9
c. b=10
Answer:
the values 9 and 10 satisfy the given inequality.
Step-by-step explanation:
Given inequality is:
[tex]5<b-3[/tex]
In order to find, which value of b satisfies the given inequality, we have to put the given values one by one in the inequality
Putting b = 8
[tex]5<8-3\\5 <5[/tex]
The inequality is not true for b=8.
Putting b=9
[tex]5<9-3\\5<6[/tex]
As the inequality is true for b=9, it satisfies the inequality.
Putting b=10
[tex]5<10-3\\5<7[/tex]
As the inequality is true for b=10, it satisfies the inequality.
Hence,
the values 9 and 10 satisfy the given inequality.
Answer:
The answer is b=9 and b=10

Marcus gives eight cookies to his friend if this represents 40% of cookies in the package what is the total number of cookies in the package
Answer:20
Step-by-step explanation:
I done 8+8+4=20 because 8 was 40% so I added another 8 that made a 80% so then I cut the 8 and half because all I needed was
20% then which would be half of 40% and I ended up with 20 and that equally gave me a hundred percent
what’s the value of x trigonometry question
Answer:
x=9.2394
Step-by-step explanation:
It's tan we're going to use because we're looking for the opposite and we already have the angle
Therefore, x will be
Tan 57= x/6
1.5399= x/6
x= 6*1.5399
x= 9.2394
You can approximate it to the nearest whole number which will be 9

Given:
The expression is
[tex]2x^4+2x^3-x^2-x[/tex]
The steps are given.
To find:
The mistake in her steps.
Solution:
We have,
[tex]2x^4+2x^3-x^2-x[/tex]
The correct steps are shown below.
Step 1: Taking out x as common factor.
[tex]=x(2x^3+2x^2-x-1)[/tex]
Step 2: Now, taking out 2x² as common factor from first two terms (first group of terms) and -1 form last two terms (second group of terms) in the parentheses.
[tex]=x(2x^2(x+1)-1(x+1))[/tex]
Step 3: Taking out (x+1) as common factor.
[tex]=x(2x^2-1)(x+1)[/tex]
She incorrectly factored -1 from the second group of terms.
Therefore, the correct option is B.

Which of the following shapes are squares ? Please choose 2 correct answers !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!
Answer:
B,D
Step-by-step explanation:
Answer:
Hello again! Your answer would be B and D
Step-by-step explanation:
A square is a shape with 4 sides and all of them have to equal. Right away you can see that D is without needing to look at it. You might think that B is not because of its angle but if you turn your paper/computer to the side a bit you can there see that it is square. C and A are not because of their unequal sides. Yes, they do have four sides but they are non-equal.
