Answer:
[tex]x = 16[/tex]
Step-by-step explanation:
[tex]3x + 5 + 9x - 19 = 180[/tex]
[tex]12x - 12 = 180[/tex]
[tex]12x = 180 + 12[/tex]
[tex] \frac{12x}{12} = \frac{192}{12} [/tex]
[tex]x = 16[/tex]

A coin is flipped 18 times. Three of the times the coin landed on heads and the rest of the times tails. What is the difference between the THEORETICAL and EXPERIMENTAL probability of landing on heads? *
Answer:
the experimental probability is based on the results of the experiment which yielded heads 1 out of 6 times; in theory, the results of flipping a coin and landing on heads would be 1 out of 2

Brooke multiplied 3 and 9 and got 17 Brooke knows her answer is wrong because she know it should be approximately
Answer:
Kindly check explanation
Step-by-step explanation:
If Brooke multiplied 3 by 9 and obtained 17 ; then Brooke is definitely wrong
3 * 9 = exactly 27
However, for approximation sake ;
We could round 9 to 10 ; and multiply 10 by 3
10 * 3 = 30 ; this gives an approximate solution for the multiplication problem ;
3 * 9 = exactly 27 or approximately 30

A store pays $22 for a surfboard. The store marks up the price by 37%. What is the amount of the mark-up?
Answer:
$8.14
Step-by-step explanation:
Given data
Cost of surfboard= $22
Mark up = 37%
Required
The amount of the markup
let us find 37% of $22
=37/100*22
= 0.37*22
= $8.14
Hence the amount of the markup is $8.14

y- 4/5=1
what does y equal to?
Answer:
y=1.8
Step-by-step explanation:
first change the fraction into a decimal.
4/5 =0.8
plus the 0.8 to both sides
y=1.8
Answer:
[tex]y - \frac{4}{5} + \frac{4}{5} = 1 + \frac{4}{5} \\ y = \frac{5 + 4}{5 } \\ y = \frac{9}{5} [/tex]

I think it’s c?
Answer:
B. f(x) = -x + 2
Step-by-step explanation:
First, you find the point on the y-axis which is (0,2) in this problem.
This will be your b in y = mx+ b
Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.
This will be your m in y = mx + b
But we don't write the 1 so it will just be -x
Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2

in a bowl there are 20 Hershey bars and 50 bags of skittles. what is the ratio of skittles to hershey bars in the bowl
Answer:
5:2 or in other words 5 to 2
Step-by-step explanation:
The original ratio would be 50:20, but we can divide both sides by 10 to simplify our answer to 5:2.
Answer:
5:2 Or 50:20 (5:2 is the simplified version)

Function f approximately represents the trajectory of an airplane in an air show, where x is the horizontal distance of the flight, in kilometers. What is the symmetry of the function?
Answer:
[tex](\frac{3}{2},102)[/tex]
Step-by-step explanation:
Given
[tex]f(x)=88x^2-264x+300[/tex] --- Missing from the question
Required
The symmetry
First, we express f(x) as: [tex]f(x) = a(x - h)^2 + k[/tex]
Where the symmetry is: (h, y) and x = h
Equate f(x) to 0
[tex]88x^2-264x+300 = 0[/tex]
Subtract 300 from both sides
[tex]88x^2-264x+300 - 300= 0 - 300[/tex]
[tex]88x^2 - 264x= - 300[/tex]
Factorize
[tex]88(x^2 - 3x) = -300[/tex]
On the left-hand side, the coefficient of x is -3.
Divide by 2 and add the square to both sides.
So, we have:
[tex]88(x^2 - 3x) + (\frac{3}{2})^2 = -300 + (\frac{3}{2})^2[/tex]
Multiply the new terms by 88 (to make it factorizable)
[tex]88(x^2 - 3x ) +88* (\frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
Factorize
[tex]88(x^2 - 3x + (\frac{3}{2})^2) = -300 + 88 * (\frac{3}{2})^2[/tex]
The quadratic expression in the bracket is a perfect square. This gives:
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * (\frac{3}{2})^2[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 88 * \frac{9}{4}[/tex]
[tex]88(x - \frac{3}{2})^2 = -300 + 22 * 9[/tex]
[tex]88(x - \frac{3}{2})^2 = -102[/tex]
Add 102 to both sides
[tex]88(x - \frac{3}{2})^2 +102= -102 + 102[/tex]
[tex]88(x - \frac{3}{2})^2 +102= 0[/tex]
Equate to y
[tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
Recall that:
The symmetry is: (h, y)
By comparison with [tex]f(x) = a(x - h)^2 + k[/tex] and x = h
[tex]h = \frac{3}{2}[/tex]
So: [tex]x = \frac{3}{2}[/tex]
Substitute [tex]x = \frac{3}{2}[/tex] in [tex]y = 88(x - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(\frac{3}{2} - \frac{3}{2})^2 +102[/tex]
[tex]y = 88(0)^2 +102[/tex]
[tex]y = 0 +102[/tex]
[tex]y = 102[/tex]
So, the symmetry is: [tex](\frac{3}{2},102)[/tex]

Oceanside bike rental shop charges seventeen dollars plus seven dollars an hour for renting a bike. Jason paid eighty dollars to rent a bike. How many hours did he have to pay to have the bike checked out?
Answer:This is a linear equation.
y = mx+b
y is the total cost.
The slope m is the rate: that's 9 dollars per hour.
x is the number of hours.
b is the initial value: that's 16 dollars.
y = 9x+16
The problem states that the cost was 79 dollars.
Substitute that for y and solve for x.
79 = 9x+16
63 = 9x
x = 7 hour
Step-by-step explanation:
Answer:
9
Step-by-step explanation:
80-17=63
63/7 = 9
7 times 9 = 63
