Are the expressions 8a2 - 4b + 7a2 and 5(3a2 - 2b) + 6b equivalent? Explain your reasoning.
Answer:
Yes, The expressions 8a² - 4b + 7a² and 5(3a² - 2b) + 6b are equivalent
Step-by-step explanation:
To answer the question you must simplify each expression, then compare them to find if they are equivalent or not
∵ The 1st expression = 8a² - 4b + 7a²
→ Add the like terms
∴ The 1st expression = (8a² + 7a²) - 4b
∴ The 1st expression = 15a² - 4b
∵ The 2nd expression = 5(3a² - 2b) + 6b
→ Multiply the bracket by 5
∴ The 2nd expression = 5(3a²) - 5(2b) + 6b
∴ The 2nd expression = 15a² - 10b + 6b
→ Add the like terms
∵ The 2nd expression = 15a² + (-10b + 6b)
∴ The 2nd expression = 15a² + -4b
→ Remember (+)(-) = (-)
∴ The 2nd expression = 15a² - 4b
∵ The 1st expression = The 2nd expression
∴ The two expressions are equivalent
∴ The expressions 8a² - 4b + 7a² and 5(3a² - 2b) + 6b are equivalent
If you can bicycle 8 miles per hour, how many minutes will it take to bicycle 4 miles?

Answer:
$4(12)
$48
Step-by-step explanation:
The problem is telling you fees are $4 per month. It is asking the amount of fees for a year.
You find the yearly amount by multiplying the monthly amount by the number of months in a year:
(fees for year) = (fee for month)×(number of months in a year)
All it is asking for is the product expression:
$4 × 12

Nami is wrapping packages with green and pink ribbon.She has 11.85 meters of green ribbon and 13.4/of pink ribbon. How many more meters of pink ribbon are their than green?
Given :
Nami is wrapping packages with green and pink ribbon.
She has 11.85 meters of green ribbon and 13.4 of pink ribbon.
To Find :
How many more meters of pink ribbon are their than green.
Solution :
Length of green ribbon, g = 11.85 m .
Length of pink ribbon, p = 13.4 m .
Amount of pink more than green is :
A = 13.40 - 11.85
A = 1.55 m
Therefore, pink ribbon is 1.55 meter more than green one.
Hence, this is the required solution.

An SUV costs $26,425 and costs an average of $0.18 per mile to maintain. A hybrid model of the SUV costs $33,195 and costs an average of $0.13 per mile to maintain. After how many miles will the cost of the gas-only SUV exceed the cost of the hybrid?
Answer:
135,400 miles
Step-by-step explanation:
SUV cost = $26,425 + $0.18m
= 26,425 + 0.18m
Hybrid SUV cost = $33,195 + $0.13m
= 33,195 + 0.13m
Where,
m = number of miles
Equate the cost of the two SUVs
33,195 + 0.13m = 26,425 + 0.18m
33,195 - 26,425 = 0.18m - 0.13m
6,770 = 0.05m
divide both sides by 0.05
m = 6,770 / 0.05
= 135,400
m = 135,400 miles
The gas-only SUV exceed the cost of the hybrid after 135,400 miles

Mackenzie works as a salesperson at an electronics store and sells phones and phone accessories. Mackenzie earns a $10 commission for every phone she sells and a $4 commission for every accessory she sells. On a given day, Mackenzie made a total of $126 in commission and sold 7 more accessories than phones. Write a system of equations that could be used to determine the number of phones sold and the number of accessories sold. Define the variables that you use to write the system.
Answer:
Let p= the number of phones sold
Let a= the number of accessories sold
Step-by-step explanation:
10p+4a=126
a=p+7
The system of equation should be 10p+4a=126 and a=p+7
Given that,
Mackenzie earns a $10 commission for every phone she sells and a $4 commission for every accessory she sells. On a given day, Mackenzie made a total of $126 in commission and sold 7 more accessories than phones.Based on the above information, the equation is as follows:
Here we assume p= the number of phones sold
And, a= the number of accessories sold
So, the equations are 10p+4a=126 and a=p+7

The constant of variation for a function that is a direct variation and whose graph passes through the point (5,82) is 16.4
For a graph with x and y-axis, we can say that y is directly proportional to "x" since it is a direct variation.
If y is directly proportional to x, this is expressed as:
y = kx
k is the required constant of variation.
Since the graph passes through the point (5,82), this shows that x = 5 and y = 82
Substituting into the formula:
82 = 5k
k = 82/5
k = 16.4
Hence the constant of variation for a function that is a direct variation and whose graph passes through the point (5,82) is 16.4

The domain of a function is given by {-4,2,8}. If the function is defined by y= x +1 /3 ,then which of the following values is a member of the range?
Answer:
{-1, 1, 3}
Step-by-step explanation:
Given the function
y = (x + 1)/3
The domain are the input value x while the range are the output values given the input value x;
Given the domain {-4, 2, 8}
when x = -4;
y = (-4+1)/3
y = -3/3
y = -1
when x = 2;
y = (2+1)/3
y = 3/3
y = 1
when x = 8;
y = (8+1)/3
y = 9/3
y = 3
Hence the member of the range are {-1, 1, 3}
Evaluate the function y = 20 + 5m when m = 13.
Your answer is:
y = 85

If 3x - 9y = 21 and 6x + 3y = 21, which of these could be a value of x or y? Select all that apply.
Answer:
x = 4
y = -1
Step-by-step explanation:
3x-9y = 21
6x+3y =21
-2* (3x-9y) = -2*(21)
6x+3y = 21
-6x+18y = -42
6x+ 3y = 21
-6x+6x+18y+3y = -21
21y = -21
y --21/21
y = -1
3x-9y =21
3x - 9*(-1) = 21
3x + 9 =21
3x = 21-9
3x = 12
x = 12/3

He original price of a couch was $395.00. A store will markup the price of the couch by 25%. What is the exact price of the couch, not including tax, with this markup
Answer:
The exact price of the couch is $493.75
Step-by-step explanation:
Here, we want to find the price of the couch given the mark up percentage
Mathematically, that would be;
395 + (25% of 395)
= 395 + 25/100 * 395
= 395 + 395/4
= 395 + 98.75
= $493.75
