Answer:
$99
Step-by-step explanation:
Answer:
$99 (Verified Answer) ✅Step-by-step explanation:
The best way to solve this is to use a proportion. However, since this is a rate, we could also find the unit rate and multiply it by the number of cars Tiara is washing.
Method 1: Proportion[tex]\frac{33}{3} = \frac{x}{9}[/tex]
3x = 33 x 9
3x = 297
Now, we simply divide by 3 to get $99.
We can check this by substituting the value of x in the original proportion.
3(99) = 33 x 9
297 = 297 ✅
Method 2: Unit RateThe other way to solve this is to divide the whole expression by the number of cars to find the unit rate. In other words, how much money does she get for washing 1 car. We can then multiply this by the number of cars to get the answer.
$33/3 for 3/3 cars
$11 for 1 car
Now, we will multiply by the number of cars she washes in this question, which is 9
$11 x 9 = 99 for 1 x 9 cars
$99 for 9 cars
Again, we have the correct answer, which we have already verified by the process above. As you can see, both methods work. However, the top method is easier and since it uses algebra, is almost foolproof, so long as the algebraic processess are followed.

arc RQ = 160°
Step-by-step explanation:
The length of smaller arc RQ is twice of the inscribed angle it sees
(5x + 15) × 2 = 10x + 30
9x + 17 + 6x - 12 + 10x + 30 = 360° add like terms
25x + 35 = 360
25x = 360 - 35
25x = 325 divide both sides by 25
x = 13 now the measure of arc RQ
10x + 30 ➡ 10 × 13 + 30 = 160°

Two lines, A and B, are represented by the equations given below!
Line A: y = x - 4
Line B: y = 3x + 4
Which of the following shows the solution to the system of equations and explains why?
A. (-3,-5), because the point satisfies ONE of the equations
B. (-3,-5), because the point lies between the two axes
C. (-4,-8), because the point satisfies BOTH equations
D. (-4,-8), because the point does not lie on any axis
Answer:
The solutions to the system of equations are:
[tex]y=-8,\:x=-4[/tex]
Thus, option C is true because the point satisfies BOTH equations.
Step-by-step explanation:
Given the system of the equations
[tex]\begin{bmatrix}y=x-4\\ y=3x+4\end{bmatrix}[/tex]
Arrange equation variables for elimination
[tex]\begin{bmatrix}y-x=-4\\ y-3x=4\end{bmatrix}[/tex]
[tex]y-3x=4[/tex]
[tex]-[/tex]
[tex]\underline{y-x=-4}[/tex]
[tex]-2x=8[/tex]
[tex]\begin{bmatrix}y-x=-4\\ -2x=8\end{bmatrix}[/tex]
solve for x
[tex]-2x=8[/tex]
Divide both sides by -2
[tex]\frac{-2x}{-2}=\frac{8}{-2}[/tex]
[tex]x=-4[/tex]
[tex]\mathrm{For\:}y-x=-4\mathrm{\:plug\:in\:}x=-4[/tex]
[tex]y-\left(-4\right)=-4[/tex]
[tex]y+4=-4[/tex]
[tex]y=-8[/tex]
The solutions to the system of equations are:
[tex]y=-8,\:x=-4[/tex]
Thus, option C is true because the point satisfies BOTH equations.
You bought a magazine for $6 and 4 candy bars. If you spent a total of $14, how much did each candy bar cost?
Answer:
2$
Step-by-step explanation:
first you need to subtract the cost of the magazine from the total. now you have 8$ left, divide this by the number of candy bars, 4, and you get 2$.
don't forget to add the dollar sign, it might save you points
pls help me with this lol
Answer:
a) 95 miles
b) Chester
c) 194 miles
Step-by-step explanation:
Chart Reading
From the chart, we can know the relative distances from each place as follows:
a) From Hereford to Chester there are 95 miles
b) Kendal is 99 miles from Chester
c) If Ellen drives from Kendal to Hereford, passing by Chester, she will drive 99+95=194 miles
Note this last result is different from the direct distance from Kendal to Chester since the 201 miles are not specified if they are through Chester or not.

Find x.
A. 8
B. 12
Answer:
17²=15²+x²
289=225+x²
288-225=x²
64=x²
x=6
Answer:
8
Step-by-step explanation:
By Pythagoras theorem,
(hypotenuse)² = (altitude)² + (base)²
(17)² = x² + (15)²
(17)² - (15)² = x²
289 - 225 = x²
x² = 64
x = √64
x = 8

y = -2x + 6
The measures of the angles of a triangle solve for X
Answer:
x = 7
Step-by-step explanation:
Because this is a right triangle, one angle is a right angle (90°). All triangles have all three angle measures adding up to 180°, so the other two angles' measures add up to 90° (90 + 90 = 180).
Combine like terms of the angle measures.
6x + 9x = 15x
-3 + (-12) = -15
15x - 15
Because the sum of the measures of the two angles have to equal 90,
15x - 15 = 90
Add 15 from both sides.
15x = 105
Divide both sides by 15.
x = 7
To check, substitute 7 in both expressions.
6(7) - 3 = 39
9(7) - 12 = 51
39 + 51 + 90 (the measure of the right angle) = 180, so the value of x is 7.

therefore, 27:18 = 13:x
27/18 = 13/x
27/18 *13= x
x = 19.5

At Springfield Middle School, there are n 7th graders, and p% of them play at least one sport. Which expression represents the number of students who do not play any sports? 4©Success Academy Charter Schools 2020 A p n B .01np 0C 100 (100−p)nD .01 (1−p)nE 00(1 )n 1 −p
Answer:
(1-0.01p)/n
Step-by-step explanation:
Mathematically;
Percentage of student playing at least one sport = 100% - Percentage of students playing no sport
Mathematically, that would be;
Percentage playing no sport = 100% - p%
So, to find this in n 7th graders
we have;
(100-p)/100 * n
= 100-P/100n = 1/n - P/100n
= 1/n - 0.01p/n
= (1-0.01p)/n

A watercooler contains 160 cups of water. During practice, each person on a team fills a water bottle with 3 1/3 cups of water from the cooler. How many water bottles can a team fill from a single watercooler?
Answer: Number of water bottles a team can fill from a single watercooler = 48
Step-by-step explanation:
Given: A watercooler contains 160 cups of water.
Each person on a team fills a water bottle with [tex]3\dfrac13[/tex] cups of water from the cooler.
Here, [tex]3\dfrac13=\dfrac{10}{3}[/tex]
Now , Number of water bottles a team can fill from a single watercooler = [tex]160\div \dfrac {10}3[/tex]
[tex]=160\times\dfrac3{10}\\\\=16\times3=48[/tex]
Hence, Number of water bottles a team can fill from a single watercooler = 48
Number of water bottle IT team can feel a single watercooler =48

Answer:
x = - 3, x = - 2, x = 0
Step-by-step explanation:
Given
x³ + 5x² + 6x ← factor out x from each term
= x(x² + 5x +6) ← factor the quadratic
Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)
The factors are + 2 and + 3 , since
2 × 3 = + 6 and 2 + 3 = + 5 , thus
x² + 5x + 6 = (x + 2)(x + 3) , and
f(x) = x³ + 5x² + 6x = x(x + 2)(x + 3)
To find the zeros equate f(x) to zero, that is
x(x + 2)(x + 3) = 0
Equate each factor to zero and solve for x
x = 0
x + 2 = 0 ⇒ x = - 2
x + 3 = 0 ⇒ x = - 3
Zeros from least to greatest are x = - 3, x = - 2, x = 0
