59-7=52(to find the number of balls that Mike gave to his friends if he gave them only one ball each)
52/4 =13(if 52 is the number of balls that he gave them if he gave them one each, if he gives them four balls each all you have to do is to divide it by 4)
Solve the following equation for X to find the total number of people who downloaded songs for music site for a certain month.
X= 0.6x + 384
How many people downloaded songs from the site that month?
Answer:
960
Step-by-step explanation:
x=0.6x+384
0.4x=384
960
Answer:
960
Step-by-step explanation:
x = 0.6x + 384
Subtract 0.6x in both sides:
0.4x = 384
Divide both sides by 0.4:
x = 384/0.4
x = 960

Given CH with C(2, 1) and H(-2,-15), find
the coordinates of E if E divides CH three

The coordinate of E will be (1, -3) if the coordinates of E if E divides CH three -fourths of the way from C to H
Midpoint of a line is a point that divides a line into two equal parts.
If the line is divided in the ratio a:b, then the midpoint formula will be expressed as:
[tex]M(X,Y) =(\frac{ax_1+bx_2}{a+b}, \frac{ay_1+by_2}{a+b})\\[/tex]
Given the coordinate points, C(2, 1) and H(-2, 15) divided in the ratio of 3:4
[tex]X = \frac{3(2)+1(-2)}{3+1}\\X= \frac{6-2}{4}\\X=\frac{4}{4}\\X = 1[/tex]
Get the coordinates Y:
[tex]Y = \frac{3(1)+1(-15)}{3+1}\\Y= \frac{3-15}{7}\\Y=\frac{-12}{4}\\Y= -3[/tex]
This shows that the coordinate of E will be (1, -3)

Three friends were at a festival together and they won 20 small prizes. They decided to split the prizes as evenly as possible. How many prizes will they each get?
Answer:
they would each get 6 and there would be 2 left over
Step-by-step explanation:
3x6=18
20-18=2
=2 leftovers
Answer:
Each of the friends will get 6 with 2 small prizes remaing
Step-by-step explanation:
20 ÷ 6 = 18 remainder of 2
Ignore the 2 because you cannot split 2 evenly from 3 people.
So each friend gets 6, while there is a 2 remainder
To check our work just do 6 × 3 = 18 and 20 - 18 = 2
So, in conclusion, each friend get 6 while there are 2 small prizes left
Write the equation of the line that passes through the points
(3,-2) and (6, 1).
y=x-5
y = 5x + 1
y = -x + 5
Answer:
It is y = x - 5
Step-by-step explanation:
General equation of a line:
[tex]{ \bf{y = mx + c}}[/tex]
m is the gradient, and c is y-intercept.
For gradient:
[tex]slope = \frac{y_{2} - y_{1} }{x _{2} - x_{1}} [/tex]
substitute:
[tex]slope = \frac{1 - ( - 2)}{6 - 3} \\ \\ = \frac{3}{3} \\ slope \: = 1[/tex]
m = 1
for y-intercept:
consider point (6, 1):
[tex]y = mx + c \\ 1 = (6 \times 1) + c \\ 1 = 6 + c \\ c = 1 - 6 = - 5[/tex]
therefore:
[tex]{ \sf{equation \: is \: \{y = x - 5 \}}}[/tex]

Answer:
C
Step-by-step explanation:
We want to solve the inequality:
[tex]\displaystyle 5.1(3 + 2.2x) > -14.25 - 6(1.7x+4)[/tex]
Distribute:
[tex](15.3+11.22x) > -14.25 + (-10.2x-24)[/tex]
Combine like terms:
[tex]15.3 + 11.22x > -10.2x-38.25[/tex]
We can add 10.2x to both sides:
[tex]15.3 + 21.42x > -38.25[/tex]
Subtract 15.3 from both sides:
[tex]21.42x > -53.55[/tex]
And divide both sides by 21.42. Hence:
[tex]\displaystyle x > -2.5[/tex]
This means all values greater than -2.5. Hence, in interval notation:
[tex](-2.5, \infty)[/tex]
In conclusion, our answer is C.

Cupcakes Promotion All cupcakes at $2 each !
Buy 8 and get 1 free!
How many cupcakes will Fatimah get if she paid $80 during the promotion?
Answer:
45
Step-by-step explanation:
....................
Hey there! I'm happy to help!
We see that the cupcakes are $2, but for every 8 you buy you get 1 free.
So, if we buy 8 cupcakes, we will be paying $16, but we will actually be receiving 9 donuts, so that means that for every $16 we pay, we get 9 donuts.
Let's see how many times $16 goes into $80.
80/16=5
So, this means that our $16 that gives us 9 donuts was done 5 times, which totals up to 80 dollars. Let's multiply our donuts now.
9*5=45
So, Fatimah will get 45 donuts during the promotion.

can someone help pls
Answer:
[tex]x=5[/tex]
Step-by-step explanation:
1. Approach
The most logical steps to solve the given equation are to distribute and simplify the left side of the equation. Then use inverse operations to bring all of the terms to the left side of the equation. After doing so, one can factor the equation again, then use the zero-product property to solve it.
2. Simplify
Distribute the terms on the left side, multiply everything in the first parenthesis by everything in the second,
[tex](x+1)(x-11)=-36[/tex]
[tex](x)(x)+(1)(x)+(-11)(x)+(1)(-11)=-36[/tex]
Simplify this expression by performing the multiplication and then combining like terms,
[tex](x)(x)+(1)(x)+(-11)(x)+(1)(-11)=-36[/tex]
[tex]x^2+x-11x-11=-36[/tex]
[tex]x^2-10x-11=-36[/tex]
Inverse operations,
[tex]x^2-10x-11=-36[/tex]
[tex]x^2-10x+25=0[/tex]
3. Factor and solve,
Now that has the simplified version of the equation, one should factor it. Rewrite the quadratic expression as a product of two linear expressions,
[tex]x^2-10x+25=0[/tex]
[tex](x-5)^2=0[/tex]
Use the zero product property to solve this expression. The zero product property states that any number times zero equals zero. Since ([tex](x-5)^2[/tex]) is just ([tex]x-5[/tex]) multiplied by itself, thus, when solving, one can ignore the square part of the equation:
[tex](x-5)^2=0[/tex]
[tex]x-5=0[/tex]
Inverse operations,
[tex]x-5=0[/tex]
[tex]x=5[/tex]

9. A doctor charges each patient $75 per consultation. If she works for 6 hours during one day and sees an average of six patients per hour, what was her profit that day? (Her costs per day are $200 for insurance, $200 for leasing the building and $50 for paying the reception desk).
Answer:
She makes $2,250/day
Step-by-step explanation:
$75 x 6 = $450 (amount of patients seen)
$450 x 6 = $2,700 (amount of hours she works)
$2,700 - $450 = $2,250 (the cost of the building, reception desk, & insurance)
We are given that the doctor charges $75 for each patient
In each she sees an average of 6 patients so,
Charge each hr = $75(6) = $450
For each hr she receives $450
So, for 6 hrs she receives = $450(6) = $2700
She pays for all the stuff = $200 + $200 + $50 = $450
Profit = Selling Price - Cost Price
Profit = $2700 - $450
Profit = $2250
Hence, she earns a profit of $2250 that daySegment addition postulate
