Answer:
12x^227xy^2 - 20xy4y^3
Step-by-step explanation:
(-3x5y) (-4x9y^2)
first : -3x (-4x9y^2) = 12x^227xy^2
second: 5y(-4x9y^2) = -20xy45y^3
then we add them (12x^227xy^2) + ( -20xy45y^3)
= 12x^227xy^2 - 20xy45y^3

2)C

Your welcomeee
Answer:
1. a
2. c
3. a
4. b
Step-by-step explanation:
1. Factor 15x + 35 using the GCF
The GCF (Greatest common factor) between these two numbers is 5. In other words, both 15x and 35 can be divided by 5. So if you divide both by 5 and then multiply it by 5, you will get 5(3x + 7), or "a".
2. Which expression is equivalent to -5(x + 10)?
Multiply the x and 10 by -5. You will get -5x - 50, or "c"
3. Subtract (8x + 6) - (x + 4)
Multiply the second parentheses by -1 (because there is a subtraction sign in front of it. This is the same as + (-1)), and then open the parentheses.
8x + 6 - x - 4
7x + 2, or "a"
4. Add (11x + 2) + (9x - 4)
Open the parentheses
11x + 2 + 9x -4
20x -2, or "b"

One year, the population of a city was 354,000. Several years later it was 407,100. Find the percent increase.
Answer:
15%
Step-by-step explanation:
GIven data
Initial population= 354,000
Final population=407,100
%Error= Final- Initial/initia*100
%Error= 407,100- 354,000/ 354,000*100
%Error= 53100/ 354,000*100
%Error=0.15*100
%Error=15%
Hence the error is 15%

Belvedere goes to the store and buys a soccer ball for $50. The store
is running a discount of 10%. What is the price of the soccer ball after
the discount?
Answer:
$45 after the discount
Step-by-step explanation:
Set up a proportion.
[tex]\frac{x}{50} = \frac{10}{100}[/tex] $50 is the total amount and make the 10% a decimal
x(100) = 50(10)
100 = 500
100 ÷ 500
x = 5 <-- We have to subtract this amount from the total
$50 - $5 = $45 <-- total after the discount
Hope this helps!!

Vivian needs to ride her bike to her friend’s house 96 miles away. She is riding at an average speed of 15 miles per hour. She has 6 hours to get there. Will she make it?
Answer:
No.
Step-by-step explanation:
If she is riding 15 miles per hour (the rate), and she has six hours (the time), then in order to find out the distance, we multiply the rate*the time.
15*6 = 90
90<96
So, no, she will not make it.

I need help like actual help
Answer:
look at the explanation
Step-by-step explanation:
hey hey. i’ll help you. sorry if this is long. :)
okay so let’s think about this. there’s a lot of extra information that we don’t need so let’s get rid of everything up to ”7 years”.
now.. she works 40 hours per week right? and she makes $2.13 per hour. so now that we have that, let’s think what 40 x $2.13 is. if you do the math right you should get 85.2 or $85.20. so that’s in one week, but then in a typical week sheserves 75 tables that have an average bill of $4q. so now that we have those numbers, we take 41 x 75 then add it to our weekly number. so we multiply the two together and we get 3075. not 30.75 but $3075.00! so take that and add it to 85.20.. you should get 3160.2, or $3160.20. but then typically an 18% tip, so let’s go back to the number before (41) and find what 18% of 41 is.
18% of 41 is 7.38 or in this case, $7.38. so once we have that, you’re gonna want to multiply 7.38 by 75 to get that total. if you do that you should get 553.5
okay.. now we have all the numbers we need. we’re already basically done, we just need to add the tips to the other total!
$3160.20 + $553.50 = $3713.70
so in a week, she makes $3713.70
i hope this helped you! good luck!

Maggie is trying to find the best deal to buy bags of potato chips. Option A: $0.90 for 9 bags of chips Option B: $0.84 for 7 bags of chips Option C: $1.50 for 5 bags of chips Which option is the better deal?
A
Option A
B
Option B
C
Option C
Answer:
The answer is option A. Since you would be paying 0.10 for each bag.
The solution is Option A.
The best deal for Maggie to buy the bag of potato chips would be 9 bags for $ 0.90 because each bag cost $ 0.10
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of each bag be represented as A
Now , the equation will be
a)
$0.90 for 9 bags of chips
The cost of 9 bags = $ 0.90
The cost of 1 bag A = The cost of 9 bags / 9
Substituting the values in the equation , we get
The cost of 1 bag A = 0.90 / 9
On simplifying the equation , we get
The cost of 1 bag A = $ 0.10
b)
$0.84 for 7 bags of chips
The cost of 7 bags = $ 0.84
The cost of 1 bag A = The cost of 7 bags / 7
Substituting the values in the equation , we get
The cost of 1 bag A = 0.84 / 7
On simplifying the equation , we get
The cost of 1 bag A = $ 0.12
c)
$1.50 for 5 bags of chips
The cost of 5 bags = $ 1.50
The cost of 1 bag A = The cost of 5 bags / 5
Substituting the values in the equation , we get
The cost of 1 bag A = 1.50 / 5
On simplifying the equation , we get
The cost of 1 bag A = $ 0.30
Therefore , the 0.10 < 0.12 < 0.30
Hence , the cost of $0.90 for 9 bags of chips is the best deal
