The symbol "<=" without quotes means "less than or equal to"

-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2

Softa [21]

Answer:

140

Step-by-step explanation:

Given:

In the Stone Ridge apartment complex 35% of the apartments have one bedroom.

If there are 49 one bedroom apartments.

Question asked:

What is the total number of apartments at Stone ridge ?

Solution:

<u>Let total number of apartments at Stone ridge</u> = x

Now according to question:

35% of the total apartments having one bedroom = 49

35\%\ of x = 49

\frac{35}{100}\times x = 49

\frac{35x}{100} = 49

By cross multiplication:

35x = 49\times100\\35x= 4900\\

By dividing both sides by 35

\frac{35x}{35} = \frac{4900}{35} \\x = 140

Therefore, total number of apartments at Stone ridge is 140

serious [3.7K]

Answer:

516 students preferred pizza

Step-by-step explanation:

To solve this problem we have to calculate 60% of the total students (860)

To get the percentage of a number we have to divide by 100 and then multiply by the number it indicates, in this case 60

860 %60 = 860 / 100 * 60

860 / 100 * 60 =

8.6 * 60 = 516

60% of 860 is 516

this means that for Friday lunches 516 students preferred pizza
