To solve for variable equations or inequalities, we want to do two things:
1. Reduce one side to variables only
2. Reduce that side to the variable without coefficients.

The given equation is 2x=-2x+11.

Let's perform step 1: reducing one side to variables only. By adding 2x to both sides of the equation, we get 4x=11.

Now let's perform step 2: reducing that side to the variable without coefficients. Since the coefficient of 4x is 4, we need to divide both sides of the equation by 4: x=\frac{11}{4}=2.75. Rounded to the nearest tenth, x=2.8.

So the value of x that satisfies 2x=-2x+11 is x=2.8.

Maureen measured a house and its lot and made a scale drawing. The scale she used was
PIT_PIT [208]

The most appropriate choice for unitary method will be given by-

Length of driveway  in the drawing is 3 inch

What is unitary method?

Unitary method is the method in which value of a single unit can be calculated from the value of a multiple unit and value of a multiple unit can be calculated from the value of a single unit.

Sometimes value of single unit is less than value of multiple unit

For example - cost of food and quantity of food

Sometimes value of single unit is more than value of multiple unit

For example- Number of men and time taken by those men to do a work

Here,

Scale used by Maureen is 1 inch = 8ft

Actual length of house's driveway = 24 feet

8 ft of room is equal to 1 inch on scale

1 ft of room is equal to \frac{1}{8} inch on scale

24 feet of room is equal to \frac{1}{8} \times 24 inch on scale

24 feet of room is equal to 3 inch on scale

Length of driveway  in the drawing is 3 inch

Hey can you please help me posted picture of question
MAXImum [283]
The correct answer is option B

(5 + 3i)(4+ 2i)

= 5(4+2i) + 3i(4+2i)

= 20 +10i + 12i +6i²

= 20 +22i +6(-1)

= 20 + 22i - 6

= 14 + 22i
