Mathematics

german3 years ago
3 0

Answer:

7c - 11

Step-by-step explanation:

To solve this, you are going to need to add like terms.

Since 5 and 2 both have a "c" next to them, you can add those together to equal 7c.

Then, since -13 and 2 do not have a "c", you can combine those together to equal -7.

Since there is no = , the closest you can get to solving this equation would then be 7c - 11.


Hope this helped!

Huw has a maths test. the second question is:
xeze [42]

Huw's answer of 9 days is incorrect because more guests would finish the food in less time so the number of days for 30 guests is less than 6 days.

The number of days that the food can last 30 guests is 4 days.

<h3>How long will Seaview Hotel's food feed 30 guests?</h3>

More guests would eat the food faster which means that it would be finished in less days than the 6 days used by 20 guests.

To find the days the food would last 30 guests, use the inverse proportion formula:
= (Number of guests x Number of days food lasts for guests) / New number of guests

= (20 x 6) / 30

= 4 days

Full question is:

The only food provided for guests at Seaview Hotel is breakfast. The hotel has enough food to make breakfast for 20 guests for 6 days. How long would the food last 30 guests? You may assume each guest eats the same amount of food for breakfast.

Without working out the correct answer, explain why Huw’s answer of 9 days is incorrect.

The sales tax in your city is 8.8%, point, 8, percent, and an item costs $63$, before tax.
PIT_PIT [208]

You would pay $5.54 on that item.

Step-by-step explanation:

Given,

Cost of item = $63

Sales tax rate = 8.8%

Amount of sales tax = 8.8% of cost of item

Amount of sales tax = \frac{8.8}{100}*63

Amount of sales tax = \frac{554.4}{100}

Amount of sales tax = $5.54

You would pay $5.54 on that item.
