(3)
The sum of a number and two is five

How many terms are in the following expression?

7x2+ 5x – 3

2

3

4

5

1, False

2, the sum of a number and two is 5 (n + 2 = 5)

2, 5n=2 (5 times a number is 2)

2, n÷2=5 (The quotient of a number and 2 is 5)

2, 5+2=n (5 added to 2 is a number)

The last one from number two that you put in number 3, x+2=5 (The sum of a number and two is five)

3, There are four terms.

Step-by-step explanation:

Hope it helps!

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

idk man good luck man
