Will is asked to simplify the expression below. 7x - 2(x + 3y) + 3y He states that the simplified expression is 5x + 9y because using the distributive property yields 7x - 2x + 6y + 3y and then combining like terms yields 5x + 9y. 1. What is the error in Will's reasoning? 2. Write the correct simplified expression for 7x - 2(x + 3y) + 3y

Answer:

20 movies

Step-by-step explanation:

x = number of movies

(75 + 2x) = 5.75x

2x = 5.75x - 75

3.75x = 75

x = 20

Answer:

(0, 5000)

The value of the account at the start of the year is 5000

Step-by-step explanation:

Given the equation that represents the  value, y, of one account that was left inactive for a period of x years as;

y = 5000(0.98)^x

The y-intercept of the equation occurs at x = 0

Substitute x = 0 into the expression

y = 5000(0.98)^0

y = 5000(1) (any value raise to power of zero is 1)

y = 5000

Hence the y intercept is (0, 5000)

This means that the value of the account at the start of the year is 5000

Answer:

Each girl (m) had $18.

Step-by-step explanation:

The Equation to determine the amount of money, m, each girl received is 4m = 72 or m = 12(4) + 24

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Each girl spent $12.

Afterward, the girls had $24 altogether.

let each Girl received amount of $x.

So, the four spend = 12 x 4 = $48

Then, the total they have = 48 + 24 = $72

So, each of Girl have = 72/ 4 = $18.

Answer:

a = 10.5 feet

Step-by-step explanation:

Given that,

The area of a square room, A = 110.25 ft²

We need to find the side length of the living room. Let the side be x.

We know that,

The area of a square, [tex]A=a^2[/tex]

So,

[tex]a=\sqrt{110.25} \\\\a=10.5\ ft[/tex]

So, the side length of the living room is equal to 10.5 feet.

Answer: .4

Step-by-step explanation:

The median means the middle of a list of numbers so rearrange the numbers from smaller to greatest:

Answer:

58° , 122° , 29°

Step-by-step explanation:

The triangle on the left has 2 congruent sides thus is isosceles.

Then the 2 base angles are congruent, so

∠ 1 = [tex]\frac{180-64}{2}[/tex] = [tex]\frac{116}{2}[/tex] = 58°

∠ 2 and 58° are adjacent angles and supplementary, that is

∠ 2 + 58° = 180° ( subtract 58° from both sides )

∠ 2 = 122°

The triangle on the right has 2 congruent sides and is isosceles

Then the 2 base angles are congruent, so

∠ 3 = [tex]\frac{180-122}{2}[/tex] = [tex]\frac{58}{2}[/tex] = 29°
