Answer:
In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics. It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields.
Step-by-step explanation:
What angle pair are you talking about?
I believe it is Infinitely Many Solutions
Answer: b. 51 - 3
Step-by-step explanation:
Given, Easha has 3 less than 5 times the number of quarters (I) that Isabelle has.
Here I is the number of quarters that Isabelle has.
Then, as per given,
Number of quarters Easha has = 5 ( number of quarters that Isabelle has) -3
= 5I-3
Hence, the expression shows the number of quarters Easha has is "5I-3"
So the correct option is b.
Yes, there are many possible answers. An equation that can model your situation is:
4a+4b=75, with a being the amount of adult tickets sold, and b being the amount of children’s tickets sold.
Because both tickets cost 4 dollars, you would multiply the amount of tickets sold, by the price (in dollars) of the ticket.
So, you can find possible answers by substituting the amount of adult tickets sold. Say, 4 adults bought tickets. You could then substitute a for 4. So the equation would look like this.
4(4)+4b=75
16 + 4b = 75
4b = 75 - 16
4b = 59
Divide each side by four
B = 14.75
The reason you got a decimal number is because 75 cannot be divided by 4 evenly. So, in this context, you could say that 15 children bought tickets. One child had an issue, and Lisa gave them a 25% discount. This would explain why there are only 75 dollars worth in tickets. I hope I helped, this is my first question I have ever answered so I’m not entirely sure if this was helpful or not. Hope you figure this out!
