Answer:
Question 6: 26 crowns plus 15 ribbons.
Question 7: 10 footballs plus 42 basketballs.
Step-by-step explanation:
Question 6 explanation: Since the expression is 22 crowns plus 13 ribbons plus 2 ribbons plus 4 crowns, you can think of the different items as variables in an equation. Picture crowns are the variable [tex]x[/tex], and ribbons as the variable [tex]y[/tex], this will help you solve the equation in an easier way that allows you to comprehend each step better. The equation will now be [tex]22x+13y+2y+4x[/tex], in order to find how many [tex]x[/tex] (crowns) and [tex]y[/tex] (ribbons) you have, you need to combine like terms in the expression. In other words, add the terms with the variable [tex]x[/tex] together, and add the terms with the variable [tex]y[/tex] together. Simplified, the equation will be [tex]26x+15y[/tex]. Since the variables [tex]x[/tex] and [tex]y[/tex] were used to represent crowns and ribbons respectively, that means the correct answer is 26 crowns plus 15 ribbons.
Question 7 explanation: You can use the same method as you did in question 6, think of footballs and basketballs as the variables [tex]x[/tex] and [tex]y[/tex] respectively. The equation will be [tex]16x+38y-6x+4y[/tex] = [tex]10x+42y[/tex]. Since the variable [tex]x[/tex] was used to represent footballs and the variable [tex]y[/tex] was used to represent basketballs, that means the correct answer would be 10 footballs plus 42 basketballs.
