18. Mabel gave Margo a bag containing red, white, and
blue marbles. The bag contained half as many red
marbles as blue ones, and 1/4 of the marbles in the
bag were white. If 8 of the marbles were red, how
many marbles were in the bag?
Answers
So the answer comes out to be 30 marbles in the bag
Answer:
32.
Step-by-step explanation:
Let the number of red marbles be x then the number of blue = 2x
So we have 8 red and 16 blue marbles.
If the total number of marbles are y marbles the number of white one = y/4.
So y = y/4 + 8 + 16
3/4y = 24
y = 24 * 4/3
= 96/3
= 32 marbles.

Answer:
60 degrees.
Step-by-step explanation:
BC is parallel to the x axis (because B and C have the same y-coordinate).
Slope of AB is 3/√3 = √3
so the angle AB makes with the axis = angle it makes with BC
= arctan(√3)
= 60 degrees.

A trader sold 250 articles for $525,000.00 at a profit of 25%.
a.Calculate the cost of each article.
b.If the trader had wanted 45% profit on the cost price then how much would he sell the articles?
Answers
Answer:
a. $2100 b. $945000
Step-by-step explanation:
You have to divide 525000 and 250 to solve for "a". To solve for "b" you need to find %100 of the profit and do %100 of the profit times 0.45 to see how much is %45 of profit.

Use the graph of f to find F(2).
A. 0.5
B. Does not exist
C. -8
D. -0.5
Answers
Hey there! Before we start with the problem, you mean f(2) instead of F(2) if I'm correct. In maths, variables are case-sentitive so F and f both are different.
First, f(2) means the value of y at x = 2.
f(2) is when we substitute x = 2 in and receive the output (y-value).
In coordinate plane, we have (x,y) as a point. What we have to do is to look at the graph, you will see the point that contains (2,-8)
That's it! Refer above, f(2) is when we substitute x = 2 and get y-value.
Hence, f(2) = -8
Let me know if you have any questions!

What is the value of the expression?When the relevant factors and natural laws of a mathematical model are given values, the outcome of the calculation it describes is the expression's outcome.
The quadratic expression is given below.
⇒ 5x² - 11x + 18
The value of the expression at x = 2.4, then the value of the expression will be
⇒ 5(2.4)² - 11(2.4) + 18
⇒ 28.8 - 26.4 + 18
⇒ 20.4
The value of the expression at x = -3, then the value of the expression will be
⇒ 5(-3)² - 11(-3) + 18
⇒ 45 + 33 + 18
⇒ 96
The value of 5x² - 11x + 18 is when x = 2.4 and when x = -3 will be 20.4 and 96.

Brainliest, please!
Step-by-step explanation:
(1, 2)(x, 5) = 1/3
5 - 2 / x - 1 = 1/3
3 / x - 1 = 1/3
x - 1 = 3 / 1/3
x - 1 = 9
x = 9 + 1
x = 10
(5 - 2)/(x - 1) = -3
3 / (x - 1) = -3
So (x - 1) = -1
x = 0

Given the linear function f(x)= - 5/8x + 16, does the point (1,2) lie on the line?
Answers
For a point to lie on the line, you have to be able to plug the x coordinate into the x and the y coordinate into f(x) and the math has to be true. In this case, plug in the x and y and you get 2=-5/8(1) + 16
Simplify the math and the two sides are not equal, therefore that point does not lie on the line. Points that lie on the line are solutions that make the equation true.

Answer:

median: 14.5 (Center)
mode: 14 and 15 (because data is bimodal so there are two modes
Step-by-step explanation:
Answer:
mean = 13.2, median = 15.5, mode = 18
Step-by-step explanation:
mean = 14+15+3+15+14+14+18+15+8+16/10
= 132/10 = 13.2
median =[ (n/2)th term + (n/2+1)term ]/2
here n is even so this formula is applied and before this is done, the numbers given are to be arranged in ascending or descending order
= [10/2 + (10/2+1)]/2
= [5th term + 6th term]/2
= (15+16)/2
= 31/2 = 15.5
mode = 18

Answers
Answer:
28
Step-by-step explanation:
AB + BC = AC
14 + 3x-4 = 4x+4
Combine like terms
10 +3x = 4x+4
Subtract 3x from each side
10+3x-3x = 4x+4-3x
10 = x+4
Subtract 4 from each side
10-4 =x-4+4
6 =x
We want AC
AC = 4x+4 = 4*6+4 = 24+4 = 28
Let's see
AB+BC=AC14+3x-4=4x+43x+10=4x+410-4=4x-3xx=6AC
