Answer:
Courtney is bringing 8 snacks
Step-by-step explanation:
Chelsea's snacks are represented as 2x.
2x means 2 · (a number)
If Chelsea brought 16 snacks and the amount of snacks represented by 2x, we have to figure out what times 2 equals 16.
In order to find out, we have to divide.
16 ÷ 8 = 2
This means 2 · 8 = 16
Since the amount of snacks Courtney brings is represented as "x", she would have brought 8 snacks.
Hope this helped! :)

Given that 3x – 8y = 39
Find y when x = 3
Give your answer as an improper fraction in its simplest form.
Answer:
- [tex]\frac{15}{4}[/tex]
Step-by-step explanation:
Given
3x - 8y = 39 ← substitute x = 3 into the equation
3(3) - 8y = 39
9 - 8y = 39 ( subtract 9 from both sides )
- 8y = 30 ( divide both sides by - 8 )
y = [tex]\frac{30}{-8}[/tex] = - [tex]\frac{15}{4}[/tex]

A line passes through the point A (-2,-5) and has a slope of -9. Using the point-Slope formula, express the equation of the line in slope intercept form.
Answer:
y = -9x -23
Step-by-step explanation:
Point-slope formula gives you
y -(-5) = -9(x - (-2))
y + 5 = -9(x + 2)
y + 5 = -9x - 18
y = -9x -23

Solve the following system of equations.
2x + 5y = -18 and y = -4x
Answer:
x=1 and y= -4
Step-by-step explanation:
step one: plug -4x into y in thi]e first equation.
2x+5(-4)= -18
step two: solve for x
2x-20= -18
(add 20 to both sides to eliminate -20 on the right)
2x=2
(divide both sides by 2 to get x by its self)
x=1
step 3: now that we found the value for x plug it in to either equation and solve for y
y= -4x
y= -4(1)
y= -4

A. 2
B. -2
C. 3
D. -3
E. 1
F. -5
Answer:
-3 and 1
Step-by-step explanation:
The zeros of the given function are -3 and 1.
What are zeros of a function?The zeros of a function, also referred to as roots or x-intercepts, are the x-values at which the value of the function is 0 (f (x) = 0). The zeros of a function can be thought of as the input values that result in an output of 0.
Given is a function f(x) = (x + 3)(x - 1)/(x-2)(x + 2),
We need to find the zeros of the function,
Equate to 0,
(x + 3)(x - 1)/(x-2)(x + 2) = 0
Therefore,
(x + 3)(x - 1) = 0
x+3 = 0 and x-1 = 0
Therefore,
x = -3, x = 1
Hence, the zeros of the given function are -3 and 1.

In a bag of sweets, 6 are orange and 9 are lime. Jodi chooses a sweet at random, eats it an
then chooses a second sweet at random.
What is the probability that both sweets are the same flavour?
(3 Points)
Answer:[tex]\frac{17}{35}[/tex]
Step-by-step explanation:
Given
The bag contains 6 orange and 9 lime sweets
For both sweets of the same flavor, Jodi must either choose orange or lime
No. of ways it can be done is [tex]^6C_1\times^5C_1+^9C_1\times^8C_1[/tex]
The total no of ways of selecting two sweets out of 15 is [tex]^{15}C_1\times^{14}C_1[/tex]
The probability that both sweets are the same flavor

[tex]\frac{2y-1}{15} =\frac{y}{10}[/tex]
Answer:
y = 2
Step-by-step explanation:
Given
[tex]\frac{2y-1}{15}[/tex] = [tex]\frac{y}{10}[/tex] ( cross- multiply )
10(2y - 1) = 15y ← distribute left side
20y - 10 = 15y ( subtract 15y from both sides )
5y - 10 = 0 ( add 10 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
a customer left a tip of 25$ this is 20% of his bill. whats the price of the bill?
Answer:
i think 150
Step-by-step explanation:
Answer: $30.00
Step-by-step explanation:
First, convert the 20% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.
0.20 x $25.00=$5.00.
$25.00 + $5.00 = $30.00.
A car is traveling at a steady speed. It travels 2 1/3 miles in 3 1/2 minutes. How far will it travel in 25 minutes? In 1 hour?
Answer:
https://i.pinimg.com/originals/50/3f/9a/503f9a49a2faa03f7db90f090eea6bff.gif
Step-by-step explanation:
Answer:
Given:
A car travels 2 1/3 miles in 3 1/2 minutes.
We need to find the distance travelled in 25 minutes, in 1 hour.
So, 2 1/3= 7/3 and 3 1/2 = 7/2
Let's convert them into decimals by dividing them completely.
So, we will get 2.33 miles and 3.5 minutes.
So now we have that 2.33 miles are covered in 3.5 minutes.
Now we need to know the distance covered in 1 minute.
So, 2.33/3.5=0.67
So now we have in one minute 0.67 miles are covered.
Now distance covered in 25 minutes will be:
0.67*25 = 16.75 miles
Now distance covered in one hour:
1 hour = 60 minutes.
So, 0.67*60 = 40.2 miles
So we have distance covered in 25 minutes-16.5 miles and in 1 hour- 40.2 miles.
