The possible solutions lie in the purple shaded area. (Where the two equations overlap). You can see the only point that does not fall in that area is (0,4). Your answer would be C.

The difference of two numbers is 5. The sum of three times the larger number and twice the smaller number is 30. What is the sma

seraphim [82]

Answer: 3

Step-by-step explanation:

Let the smaller number be y.

Since the difference of two numbers is 5,then the larger number will be: y+5

The sum of three times the larger number and twice the smaller number is 30. This can be written as:

3(y+5) + 2y = 30

3y + 15 + 2y = 30

5y + 15 = 30

5y = 30 - 15

5y = 15

y = 15/5

y = 3

The smaller number is 3

class size m average 0.82 n class n average 0.78. if the average for combined classes is 80%, what is relationship between m and

katen-ka-za [31]

Answer:

The relation between m and n is , m = n

Step-by-step explanation:

Given as :

The average for n class = 0.82 = 82%

The average for m class = 0.78 = 78%

The average for ( m + n ) class = 80%

So , $\frac{x_1 +x_2+x_3+x_4+ ....... + x_n}{n}$ = 82%

And $\frac{x_1 +x_2+x_3+x_4+ ....... + x_m}{m}$ = 78%

And , $\frac{(x_1+x_2+x_3+x_4+ ......+x_n ) + (x_1+x_2+x_+x_4+.....+x_m)}{m+n}$ = 80%

So , 0.82×n + 0.78×m = 0.80× (m+n)

Or, 0.82×n - 0.80×n = 0.80×m - 0.78×m

Or, 0.02×n = 0.02×m

Or, $\frac{m}{n}$ = $\frac{0.02}{0.02}$

∴ $\frac{m}{n}$ = 1

I.e m = n

Hence The relation between m and n is , m = n Answer
