Answer:

x=6-2y

Step-by-step explanation:

3x+6y=18

Subtract 6y from both sides of the equation.

3x=18−6y

Divide each term by 3 and simplify.

Divide each term in 3x=18−6y.

3x/3=18/3+−6y/3

Cancel the common factor of 3.

x=18/3+−6y/3

Simplify each term.

x=6−2y

WRITE AN EQUATION FOR EACH OF THESE AND SOLVE IT TO FIND THE VALUE OF THE UNKNOWN NUMBER:

castortr0y [4]

a) a *5+5= 20

5a + 5 = 20

5a = 20 - 5

5a = 15

a = 15/5

a = 3

b) b/5 - 5 = 4

b/5 = 4 + 5

b/5 = 9

b =9*5

b = 45

a_n = a_ (n-1) +d

a) 2,8,14,.......

b) 8-2 =6

14-8 =6

d=6

c) a_n = a_ (n-1) +8

check:

a_1 = 2

a_2 = a_ 1 +6 = 2+6 =8

2_3 = a_2 + 6 = 8 + 6=14

a_n = a_ (n-1) +8

Wade was asked to solve this inequality:

frozen [14]

Answer:

The correct option is Option A: Yes, that is the correct step

Step-by-step explanation:

Wane was asked to solve the inequality $\large \frac{x}{3}\ge11$

He decides that he needs to multiply both sides by 3.

We need to tell if the step is correct?

So, solving the inequality

$\frac{x}{3}\ge11$

We need to multiply both sides by 3, to get value of x i.e.

$\frac{x}{3}*3\ge11*3\\x\geq 33$

So, Wanes step is correct.

The correct option is Option A: Yes, that is the correct step
