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.
To find the cost of one, divide 10.38 by 6, so
10.38/6 = 1.73
1.73 = price per battery
To find the price of 8, multiply the cost of price per battery with however many items you need, in this case 8 so,
1.73 x 8 = 13.84
-7d > 21
d < -3
Remember the sign flips when you multiply or divide by a negative number.
Answer:
C = 24
Step-by-step explanation:
(x - 6)² - 12 = x² - 12x + c
(x - 6) (x - 6) -12 = x² - 12x + c
x(x - 6) - 6(x - 6) - 12 = x² - 12x + c
x² - 6x -6x + 36 - 12 = x² - 12x + c
x² - 12x +36 - 12 = x² - 12x + c
x² - 12x + 24 = x² - 12x + c
24 = c
The answer should be gallons per minute
