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 
, and ribbons as the variable 
, this will help you solve the equation in an easier way that allows you to comprehend each step better. The equation will now be 
, in order to find how many (crowns) and (ribbons) you have, you need to combine like terms in the expression. In other words, add the terms with the variable together, and add the terms with the variable together. Simplified, the equation will be 
. Since the variables and 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 and respectively. The equation will be 
= 
. Since the variable was used to represent footballs and the variable was used to represent basketballs, that means the correct answer would be 10 footballs plus 42 basketballs.
Well assuming that this would be a typical triangle, and not a right angle one, knowing that the sum of all sides adds up to 180 degrees, simply add all of the expressions and one value and make it equal to 180, and then solve for x.
(6x-1) + (X+14) + 20 = 180
6x - 1 + X + 14 = 160
7x - 1 + 14 = 160
7x + 13 = 160
7x = 147
X = 21.
Now solve for the angles by plugging in X.
A = 6x - 1 = 6(21) - 1 = 125 degrees
C = X + 14 = (21) + 14 = 35 degrees.
I believe these are the solutions.
I hope this works
2(y-1)8=
16(y-1)
It means the scatter plot is a line with negative slope. The relation is perfectly described by a linear equation.
