Xavier is x years old and Yvonne is y years old. Yvonne is 7 years older than Xavier. Four times Yvonne’s age is equal to 200. (a) Write an equation that could be used to solve for Yvonne’s age, y. (b) How old is Yvonne? Show your work and don’t forget the unit. (c) How old is Xavier? Show your work and don’t forget the unit

Answer: $750

Step-by-step explanation:

Hi, to answer this question, first we have to calculate the markup amount by multiplying the wholesale price of the clubs (250) by the percent increase in decimal form (divided by 100):

Mathematically speaking:

250 x (200/100) = $500 (percent increase amount)

Finally, we add the percent increase amount to the wholesale price to obtain the retail price:

250+500 =$750

The linear equation can be written in the form of a, b, and y as x = (y - b)/a if the linear equation is y = ax + b.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

The linear expression is:

y = ax + b

The linear expression can define as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.

If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.

ax = y - b

x = (y - b)/a

Thus, the linear equation can be written in the form of a, b, and y as x = (y - b)/a if the linear equation is y = ax + b.

I believe you mean that x needs to be isolated?

First, divide both sides by a. You'll get Y/A = x+b. Then, subtract b from both sides, to get Y/A - B = X.

Or x= y/a - b.

The total amount of yard Jamal used is 1/2 yard              

• Amount of yard he used to tie a package = 1/3 yard
• Amount of yard he used to tie a bow = 1/6 yard

Further Explanation

To determine the overall amount of yards of ribbon that Jamal used, the amount of yard he used to tie a package and the amount he used to tie a bow will be added; the derived value is the total amount of yard he used.

Therefore,

= 1/3 + 1/6

= (2+1)/6

= 3/6

= 1/2 yard (Further broken down to this)

The above values are fractions. A fraction is a number that has a part of a whole. It always has a numerator and denominator. Numerators are number values that are always on top, while denominators are number values that are always at the bottom

To derive the final answer (1/2), both denominators (3 and 6) Lowest Common Denominator was factored out which is (6), and is used to divide both denominators, then multiplied by the numerators. The derived values were added to get another fraction which was finally broken down to arrive at the final answer.

Significantly, the order of operations i.e. BODMAS was made use of. BODMAS is an acronym of Bracket, Of, Division, Multiplication, Addition, Subtraction.
