1. Calculate the value of x in the following diagram. 53 - Y IN Q 5x 18

Answers

Answer:

x = 7

Step-by-step explanation:

QY = 5x

YZ = 18

QZ = 53

Thus:

QY + YZ = QZ (segment addition postulate)

5x + 18 = 53

5x = 53 - 18 (subtraction property of equality)

5x = 35

Divide both sides by 5

x = 7

7z^2 -38z + 15.
Select the factors of this quadratic expression.

Answers

Answer:

7z - 3 and z - 5

Step-by-step explanation:

The factors of the given quadratic expression is (z-5((7z-5).

The given quadratic expression is 7z² -38z + 15.

What is the quadratic expression?

An expression of the form ax² + bx + c, where a ≠ 0 is called a quadratic expression. In other words, any expression with the variables of the highest exponent or the expression's degree as 2 is a quadratic expression.

The given quadratic expression 7z² -38z + 15 can be solved as follows:

Using spitting middle term

7z² -35z-3z + 15

= 7z(z-5)-3(x-5)

= (z-5((7z-5)

Therefore, the factors of the given quadratic expression is (z-5((7z-5).

The slope is 2, and the y-intercept is 4.
5
The slope is 4, and the y-intercept is 2.
5
The slope is 4, and the y-intercept is 2.

Answers

Answer:

slope(m)=4 and

y-intercept(c)=-5/2

Step-by-step explanation:

here,8x-2y=5

reducing it into slop intercept form we get,

2y=8x-5

or,y=8/2x+(-5/2)

or,y=4x+(-5/2)

comparing it with y=mx+c we get,

slope(m)=4 and

y-intercept (c)=-5/2

Paul is locked out of his house. An 18-ft ladder is outside and an upstairs window is open. Paul read the safety warning on the ladder recommending it be placed six feet away from the wall. He placed the ladder according to the warning and it reached the base of the window. How high is the base of the window off the ground?

Answers

Answer:

17.0 ft

Step-by-step explanation:

Let h be the height of the base of the window from the ground, L be the length of the ladder = 18 ft and d be the distance of the ladder from the wall = 6 ft. Now, these three lengths form a right-angled triangle with the length of the ladder, L as the hypotenuse side.

So, using Pythagoras' theorem,

L² = h² + d²

So, h = √(L² - d²)

Substituting the values of L = 18 ft and d = 6 ft, we have

h = √((18 ft)² - (6 ft)²)

= √(324 ft² - 36 ft²)

= √288 ft²

= 16.97 ft

≅ 17.0 ft

Robert and his younger sister are selling gift wrap to raise funds for the middle school band. Robert's sales are 2.5 times his sister's sales. Their total sales together can be represented by the equation x+2.5x=63 . Which of these statements are true? Choose ALL that are correct. A Robert's sales are represented by x when solving 3.5x=63 . B Robert's sister's sales total $18.00. C Robert's sales are represented by x when solving 2.6x=63 . D Robert's sales total $25.20. E Robert's sister's sales are represented by x when solving 3.5x=63 .

Answers

Answer:

B. Robert's sister's sales total $18.00.

E. Robert's sister's sales are represented by x when solving 3.5x = 63 .

Step-by-step explanation:

Let

Robert sister's sales = x

Robert sales = 2.5 * x

= 2.5x

Total sales = Robert sister's sales + Robert sales

63 = x + 2.5x

63 = 3.5x

Divide both sides by 3.5

x = 63 ÷ 3.5

= 18

x = $18.00

Robert sales = 2.5x

= 2.5(18)

= $45.00

A. Robert's sales are represented by x when solving 3.5x=63 .

B. Robert's sister's sales total $18.00.

Yes

C. Robert's sales are represented by x when solving 2.6x=63 .

D. Robert's sales total $25.20.

E. Robert's sister's sales are represented by x when solving 3.5x = 63 .

Answers

Answer:

n = 9

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define

3n - 5 = 22

Step 2: Solve for n

Add 5 to both sides: 3n = 27Divide 3 on both sides: n = 9

The answer is 9 because your going to add +5 under -5 and +5 under 22 and -5+5 going to cancel out and 22 will be 27. Then it’s going to be 3n=27 divide 3 on both sides and n=9

Marshall gave the cashier $100 to pay for 4 new video games. The cashier gave him $4.08 in change. Each video game cost the same amount.

What is the cost in dollars and cents for each video game?
PLZZZZ HELP

Answers

Answer:

I would say it's $23.98

Step-by-step explanation:

If you do 100-4.08, you get 95.92 and since there's 4 video games, divide 95.92 by 4 and you get 23.98

Answer:

$23.98 or 2398 cents

Step-by-step explanation:

If the cashier gave $4.08 back, that means that he spent 100-4.08 on the 4 games.

$100 = 4 games + $4.08

4 games = $95.92

$95.92/4 = $23.98

Hope That Helps.
