You'll need to buy 45 ounces of grass seed.

60x90=5400.
5400/120=45.

Question 1:

F(x) and g(x) are like variables, just plug into the equation.

f(x) + g(x) = (x + 6) + (12x - 7)

x+6+12x-7 = 13x-1

Question 2: f(3) + g(-1)

You plug in the x-values into the equation, and then take the answer and add them together.

f(3) = 3+4

g(-1) = 12(-1)-6

f(3) = 7

g(-1) = -18

7 + (-18) = -11

Question 3:

This is similar to question 1, plug in the variables and simplify.

9x - (7x+3)

Remember to distribute the "-"

9x - 7x - 3

2x - 3

4 7/12 + 2 1/12 what is the estimate answer

Pani-rosa [81]

$4 \frac{7}{12} = \frac{12*4+7}{12} = \frac{55}{12} \\ \\ 2 \frac{1}{12} = \frac{2*12+1}{12} = \frac{25}{12} \\ \\ \frac{55}{12} + \frac{25}{12} = \frac{80}{12} \\ \\ \frac{80 :4}{4:4} = \frac{20}{3}$

The sum of the two prime numbers between 110 and 130 is

Korvikt [17]

Prime numbers are those numbers which have only two factors, 1 and the number itself . For e.g. 3,5,7,11 etc are all prime numbers.

Between 110 and 130 we have a total of two prime numbers which are 113 and 127, since both have only two factors .

And sum of 113 and 127 is

$113+127= 240$

So the required answer is 240 .
