The correct dividend of 76 is required to yeild a quotient of 25 and a remainder of 1 when divided by 3.

We can know the dividend, the quotient and the remainder of the division using the division formula: (Divisor x Quotient) + Remainder = Dividend

Divisor = 3

Quotient = 25

Remainder = 1

(3 × 25) + 1 = 75 + 1

(3 × 25) + 1 = 76

Thus, the dividend 76 divided by the divisor 3 have the quotient 25 and a remainder when of 1.

From the given parameters of linear equation, we can say that;

The number of $10 bills is; 24

The number of $20 bills is; 13

Let x be the number of the $20 dollars bills.

Then the number of the $10 dollars bills is (x + 11), according to the condition.

The money equation is expressed as;

20x + 10*(x + 11) = 500

Simplify and solve for x.  

20x + 10x + 110 = 500

30x = 500 - 110

30x = 390

x = 390/30

x = 13

Answer: 36

Step-by-step explanation:

4 sections are 2,000 lbs or 1 ton

To find the pounds Girard has to build, we know we have 9 tons, therefore if each ton is 2,000 lbs, multiply 2,000 by 9 to get 18,000 lbs to use

2,000 lbs per ton x 9 tons= 18,000 lbs to use

now take the 18,000lbs and divide by 500 to find the number of sections we can build

18,000lbs / 500 pounds per section = 36

36 sections is the answer

The present age of Melody is 9 and her sister is 24 .

How to find the ages of a person ?

Consider the difference between the individual's birthdate and the present day: days = current day - birth date. Age = (years 365) + (months 31) + days should be replaced with these variations. The individual's age is expressed in days. To get the age in years, divide the outcome by 365.

Let present age of melody be y and her sister age be x

Four years ago  age of Melody be (y - 4) and her sister age be (x - 4)

After six years age of Melody be (y + 6) and her sister age be (x + 6)

∴ [tex]\frac{(x-4)}{4} = (y - 4)[/tex]

[tex]\frac{(x+6)}{2} = (y + 6)[/tex]

The equation becomes

x + 6 = 2y + 12

x = 2y +6  ⇒ (1)

x - 4 = 4y -16

x = 4y - 12 ⇒(2)

Solving (1) and (2)

x - 2y = 6

x - 4y = -12

  2y = 18

    y = 9

Substituting the value of y in eq(1)

x = 2*9 + 6

x = 18 +6

x = 24

Let xy be the two digit number.  

10x + y

The value of this number is 6 less (-6) than five times the unit digit (5y).  So:

The sum of the digits of the 2-digit number is 12:

x + y = 12

So y = 12 - x

Substitute 12-x for y:

10x + y = 5y - 6

10x + 12 - x = 5(12-x) - 6      [Substituted 12-x in place of y]

9x + 12 = 60 - 5x - 6

14x = 42

The equation of the linear relationship in slope-intercept form is: y = 2/3x + 50/3.

The equation in slope-intercept form for a linear relationship can be expressed as y = mx + b, where the slope is m and the y-intercept is b.

Using two points on the graph, (20, 30) and (50, 50), find the slope:

Slope (m) = change in y / change in x = (50 - 30) / (50 - 20)

Slope (m) = 20/30

Slope (m) = 2/3.

Find the y-intercept (b) by substituting m = 2/3 and (x, y) = (20, 30) into y = mx + b:

30 = 2/3(20) + b

30 = 40/3 + b

30 - 40/3 = b
