5. (01.07)<br> Solve 3x - x + 2 = 12. (1 point)
mafiozo [28]

Answer:

x = 5

Step-by-step explanation:

Simplify. First, combine like terms:

3x - x + 2 = 12

(3x - x) + 2 = 12

(2x) + 2 = 12

2x + 2 = 12

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS =

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

& is your order of operation.

First, subtract 2 from both sides:

2x + 2 (-2) = 12 (-2)

2x = 12 - 2

2x = 10

Next, divide 2 from both sides:

(2x)/2 = (10)/2

x = 10/2

x = 5

5 is your answer for x.

Check: Plug in 5 for x in the equation. Solve:

3(5) - (5) + 2 = 12

15 - 5 + 2 = 12

10 + 2 = 12

12 = 12 (True)

A theatre has 50 seats on the front row. There are 4 additional seats in each following row.
alexandr402 [8]
\boxed { \boxed { T_n = a_1 + d(n - 1)}}

\text {Given that }a_1 = 50 \text { and } d = 4

T_n = 50 + 4(n - 1)

T_n = 50 + 4n - 4

T_n = 46 + 4n

\boxed { \boxed {T_n = 46 + 4n }}

When n = 20,
T_{20} = 46 + 4(20) = 126

\boxed { \boxed {\text{Answer: The 20th term is 126}}}

The area of a rectangular field is 8811 m2. if the width of the field is 89m, what is the length?
xeze [42]
Length = 99 because...
since you multiply to get the area, in order to find the missing term of an area (in this case its length), you do the opposite of what you started with...so if you multiplied to get the area, you need to divide to get the missing side...
so 8811 divided by 89 = 99
99 x 89 = 8811
