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

Answers

Answer 1

Answer: See explanation

Step-by-step explanation:

7x - 2(x + 3y) + 3y

= 7x - 2x - 6y + 3y

= 5x - 3y

Will got 5x + 9y because he didn't multiply the values in the bracket by the minus sign outside the bracket. He multiplied the values by +2 rather than -2. This resulted in the wrong answer that he got.

Answers

Answer:

20 movies

Step-by-step explanation:

4. Some banks charge a fee on savings accounts that are left inactive for

an extended period of time. The equation y = 5000(0.98)x represents the

value, y, of one account that was left inactive for a period of x years. What

is the y-intercept of this equation and what does it represent? *

Answers

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

Vera and her three sisters received the same amount of money to go to the school festival. Each girl spent $12. Afterward, the girls had $24 altogether.



Which equation can be used to determine the amount of money, m, each girl received?

Multiple choice question.

Answers

Answer:

Each girl (m) had $18.

Step-by-step explanation:

They each had $18.Then, they each spent $12.So, they each have $6; 6x4 = $24 left

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

What is Unitary Method?

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.

A square living room in a home has an area of 110.25 square feet.
What is the side length of the living room?

Answers

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.

Answers

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°
