Answer:

Question 1

Option 2 is the correct answer

y = x - 55/ x=255

Question 2:

Last option is the correct answer

n = b + 2/ b= 5

Step-by-step explanation:

Question 1

The given information can be framed into the Mathematical form as given below:

No of cards = x

Cards given to brother = 55

Remaining cards = x - 55

Total number of cards = y

y = x - 55

Plug y = 200

200 = x - 55

20. + 55 = x

x = 255

y = x - 55/ x = 255

Question 2:

Total number of shirts bought

n = b + 2

Plug n = 7

7 = b + 2

7 - 2 = b

b = 5

n = b + 2/ b = 5

The price of the product decreased by 10%and then decreased by 20% . calculate total percentage change between the final and ini
aev [14]

What is percentage change?

By quantifying the difference between two numbers and expressing it as an increase or decrease, the Percentage Change Calculator (percent change calculator) may determine the percentage change.

The initial price V_{1} (100%) was decreased by 10%., then this reduced price is reduced more by 20% that becomes the final price V_{2} which is 72.

Calculate percentage change from $V_{1}=100$ to $V_{2}=72$.

=& \frac{\left(V_{2}-V_{1}\right)}{\left|V_{1}\right|} \times 100 \\

=& \frac{(72-100)}{|100|} \times 100 \\

=& \frac{-28}{100} \times 100 \\

=&-0.28 \times 100 \\

=&-28 \% \text { change } \\

=& 28 \% \text { decrease }

The estimated total cost, y, of a child’s toy is partially based on the number of batteries used, x. The cost of one battery is
mixas84 [53]

Answer: The equation that represents the give situation is, y = 0.75 x + 12

Step-by-step explanation:

Here, x represents the number of batteries the child bought and y represents the total cost.

Since, the cost of one batteries = $ 0.75

⇒ The cost of x batteries = 0.75 x

The cost of one toy = $ 12

Hence, the total cost = The cost of one toy + The cost of x batteries

= y = 0.75 x + 12

Which is the required equation that represents the given situation.
