Answer 2

Answer:

35, 100, 1.4

Step-by-step explanation:

Each value of 10 would equal 7. This would mean that 50 would equal 35 since 7x5=35. This would also mean that 100 would equal 70 since 7x10=70. This would also make sense for the last one since 10÷3=1.4

A store sells a package of 25 trading cards for​ $5.25. What is the unit price per​ card?

Answers

The cost of one trading card obtained using the principle of proportionality is $0.21


Given the Parameters:

25 trading cards = $5.25


Let the Cost of one trading card = b


We could set up a proportional system to calculate the Cost of one trading card as
follows :

25 cards = $5.25
1 card = b


Cross multiply:

25b = $5.25


Divide both sides by 25 to isolate b



25b/25 = 5.25 / 25
b= $0.21


Therefore, one trading card costs $0.21
The numerator is smaller than the denominator what you divide 5.25 by 25 so the unit price is going to be less than 1.

The unit price is $0.21

Step-by-step explanation:

25 cards = $5.25

5.25/25 = $0.21

a. What fraction of all the students are girls with blond hair?
b. What fraction of all the students are boys without brown hair?

Answers

First, you would divide One-third by three-fifths, which would be the answer to part A.For part b if 3/5 of the students are girls then the other 2/5 of the students are boys so you would divide 2/5 by 1/2.Those should be your answers.

DUE TODAY (10/11/22) Need help on two questions!!

What term would you move using inverse operations to put this equation into standard form (Ax+By=C)

3x = 5 - 2y


5 by subtracting 5 to the other side

3x by dividing by 3 on both sides

-2y by adding 2y to other side


Natalie wanted to find the y intercept for the standard form of this equation. Here are her steps. Did Natalie make a mistake? If so, which one was her first? If not, indicate that as well.

Solve for the y intercept by substituting 0 for x.

2x + 4y = 20


Step 1: 2(0) + 4y = 20

Step 2: 0 + 4y = 20

Step 3: 4*4y = 20 * 4

Step 4: y = 80


A: Step 1

B: Step 2

C: Step 3

D: Step 4

E: Natalie made no mistakes

Answers

First problem you add 2 y second problem is step 3
#1) -2y by adding 2y to other side

#2) C: Step 3

Explanation:

#1) 5 is the only number without a variable, so isolating it would make the standard form true.

#2) Opposite of multiplication is division, so rather than multiplying 4 to both sides, Natalie should've divided.

8b + 16

2(6m +2)

I'm not really sure what the letters stand for in this context

Answers

the letters are a variable, when you have different variables you cannot plus or minus them like in this situation - 8b + 16

16 has no b's for plus 8b

2(6m +2) - in this expression we can multiply in which is 12m + 4

Ok so the letters are variables also can indicate any number so in the 8b+16 it is telling you that 8 times any number plus sixteen. And for the other variable m it is standing for when you multiply 2 times 6m which is 12m and then 2 times 2 which is four, so the inquisition for this equation would be 12m+4

Deshaun wants to buy a new MP3 player that sells for $800 . The sales tax rate is 6.7%. What is the total cost of the MP3 player with tax included?

Answers

Answer:

$853.6

Step-by-step explanation:

6.7%=.067

.067x800+53.6+800+ansewr

853.6

If you say “6.7% of $800”
that means you have to get 6.7% into number form: 6.7% = 0.067,
“of” means multiplication. so 0.067 x 800= 53.6
add the tax to the original price = 53.6 + 800= 853.6
