Answers

Answer:

x=17!

Step-by-step explanation:

3x+5=5x-29

5=2x-29

34=2x

Therefore x=17!

Answer:

x = 17

Step-by-step explanation:

Lets start evaluating

3x + 5 = 5x - 29

3x + 5 + 29 = 5x

3x + 34 = 5x

34 = 5x - 3x

34 = 2x

x = 34/2

x = 17

Quadrilateral WILDWILDW, I, L, D is inscribed in circle OOO. \overline{WI} WI start overline, W, I, end overline is a diameter of circle OOO. What is the measure of \angle D∠Dangle, D?

Answers

Answer:

135degrees

Step-by-step explanation:

Find the diagram attached.

Note that in a cyclic quadrilateral, the sum of the opposite side of the quadrilateral is 180degrres.

According to the diagram shown:

<D+<I = 180

<D+45 = 180

Subtract 45 from both sides

<D+45-45 = 180-45

<D = 180-45

<D= 135°

Hence the measure of <D is 135degrees

What is the sum of 7z/x^2 - 4

Answers

Answer:

9x-4 / (x²-4)

Step-by-step explanation:

common denominator is 'x²-4' which is (x-2)(x+2)

the term '7x' already has that denominator but 2/x+2 becomes 2(x-2)/(x²-4)

now you can add 7x to 2(x-2) which is 7x + 2x - 4 or 9x-4 and

your denominator remains as 'x²-4'

A student made an 85% on a test with 25 questions. What is the number
of questions that the student answered correctly? Round to the nearest
whole number*

Answers

the student answered 21 questions correctly to earn an 85

The student answered 21 questions correctly on a test.

What is the Multiplication operation?

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

Since the student made an 85% on a test with 25 questions.

To determine the number of questions the student answered correctly, we need to multiply the number of questions by the percentage of questions answered correctly, which is 85%.

= 25 questions × 0.85

Apply the multiplication operation, and we get

= 21.25

Rounding to the nearest whole number,

= 21 questions

Thus, the student answered 21 questions correctly.

Answers

Answer:

(C) j/j+80 and 36/k+36

Step-by-step explanation:

From the table attached :

Total Email (positive + negative) = j + 80

Number of positive Emails = j

Fraction of positive emails = (number of positive  / total number of emails) = j / (j + 80)

Total phone calls  (positive + negative) = 36 + k

Number of positive Emails = 36

Fraction of positive emails = (number of positive  / total number of emails) = 36 / (k + 36)

What is the weight of a square if a triangle weighs 4 grams? Explain your reasoning

Answers

Answer:

2 grams

Step-by-step explanation:

One can see that the given diagram is that of a balancing scale, meanig that both sides are equal to each other. Therefore,  if one calls the weight of the triangle (t), then one can form an equation. Keep in mind that it is given that the square weighs (4) grams, and therefore, the square doesn't need a variable representation.

t + 4 + 4 = t + t + t + 4

Simplify,

t + 8 = 3t + 4

Inverse operations,

t + 8 = 3t + 4

   -4          -4

t + 4 = 3t

What is the slope of (-6, 1) and (2,5)?

Answers

Answer:

Step-by-step explanation:

To find the slope given two points, use the slope formula

m= ( y2-y1)/(x2-x1)

   = ( 5-1)/(2--6)

    = (5-1)/(2+6)

    = 4/8

    = 1/2

Answer:

slope = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (2, 5)

m = [tex]\frac{5-1}{2+6}[/tex] = [tex]\frac{4}{8}[/tex] = [tex]\frac{1}{2}[/tex]

Answers

(0,0) and (6,0)

First we subtract 18x from both sides

3x²-18x=0

Factor out a 3x

Victor sold cupcakes and cookies yesterday. Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the
day, Victor had sold $95.25 worth of cookies and cupcakes. If he sold 68 cupcakes and cookies combined, how many
cupcakes were sold and how many cookies were sold?

Answers

answer:number of cupcakes sold is 13  Number of cookies sold is 27  

Step-by-step explanation:

Let x represent the number of cupcakes that Victor sold.  Let y represent the number of cookies that Jane sold.  Each cupcake sold for $2.25 and each cookie sold for $0.50. At the end of the day,  This mean Victor had 2.25x 0.5y = 42.75 - - - - - - - - - -1she sold 40 cupcakes and cookies combined, it means thatx y = 40Substituting x = 40 - y into equation 1, it becomes2.25(40 - y) 0.5y = 42.7590 - 2.25y 0.5y = 42.75- 2.25y 0.5y = 42.75 - 90- 1.75y = - 47.25y = - 47.35/-1.75y = 27x = 40 - yx = 40-27 = 13

An equation is formed when two equal expressions. The number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Let the number of cupcakes sold be represented by x, while the number of cookies sold is represented by y.

Now, the total number of cupcakes and cookies sold combined is equal to 68. Therefore, the equation can be written as

x + y = 68

x = 68 - y

Also, Each cupcake sold for $2.25 and each cookie sold for $0.50. And the total sale that Victor made is of $95.25. Therefore, the equation can be written as,

2.25x + 0.50y = 95.25

2.25(68 - y) + 0.5y = 95.25

153 - 2.25y + 0.5y = 95.25

-2.25y + 0.5y = 95.25 - 153

1.75y = 57.75

y = 33

Now, substitute the value of x in the first equation.

x + y = 68

x + 33 = 68

x = 35

Hence, the number of cupcakes that Victor sold is 35, while the number of cookies that Victor sold is 33.
