Ava is a high school basketball player in a particular game she made some three point shots and some two point shots Ava made a total of 12 shots altogether and scored a total of 28 points how many of the points were three points and how many were 2 points
Answer:
Ava made 4 three point shots and 8 two point shots.
Step-by-step explanation:
Let X represent the number of 3-point shots and Y represent the number of 2-point shots.
Then using the provided data two equations can be formed:
X + Y = 12...(i)
3X + 2Y = 28...(ii)
Solve (i) and (ii) simultaneously:
Multiply (i) by 2 and subtract (ii) from (i) as follows:
2X + 2Y = 24
-3X - 2Y = -28
-X = -4
X = 4
Substitute X = 4 in (i) and solve for Y as follows:
X + Y = 12
4 + Y = 12
Y = 8
Thus, Ava made 4 3-point shots and 8 2-point shots.

find x and y
Like the explanation of x and y?
Answer:
You didn't include anything to find X and Y, but I can help you find it in the future.
Step-by-step explanation:
In order to find X or Y in an equation, do the opposite with the last two numbers.
Example:
2x+1 = 5
You see that we are adding here.
So, we must do the opposite with 1 and 5.
1-5=4
That means that 2x will equal four, which means that x must be 2.
2x2+1=5 This is true, because 2x2=4 + 1 = 5.

You’ve studied and now you’re geared up for the ACT math section (whoo!). But are you ready to take on the most challenging math questions the ACT has to offer? Do you want to know exactly why these questions are so hard and how best to go about solving them? If you’ve got your heart set on that perfect score (or you’re just really curious to see what the most difficult questions will be), then this is the guide for you.
We’ve put together what we believe to be the most 21 most difficult questions the ACT has given to students in the past 10 years, with strategies and answer explanations for each. These are all real ACT math questions, so understanding and studying them is one of the best ways to improve your current ACT score and knock it out of the park on test day.
Brief Overview of the ACT Math Section
Like all topic sections on the ACT, the ACT math section is one complete section that you will take all at once. It will always be the second section on the test and you will have 60 minutes to completed 60 questions.
The ACT arranges its questions in order of ascending difficulty. As a general rule of thumb, questions 1-20 will be considered “easy,” questions 21-40 will be considered “medium-difficulty,” and questions 41-60 will be considered “difficult.”
The way the ACT classifies “easy” and “difficult” is by how long it takes the average student to solve a problem as well as the percentage of students who answer the question correctly. The faster and more accurately the average student solves a problem, the “easier” it is. The longer it takes to solve a problem and the fewer people who answer it correctly, the more “difficult” the problem.
(Note: we put the words “easy” and “difficult” in quotes for a reason—everyone has different areas of math strength and weakness, so not everyone will consider an “easy” question easy or a “difficult” question difficult. These categories are averaged across many students for a reason and not every student will fit into this exact mold.)
All that being said, with very few exceptions, the most difficult ACT math problems will be clustered in the far end of the test. Besides just their placement on the test, these questions share a few other commonalities. We'll take a look at example questions and how to solve them and at what these types of questions have in common, in just a moment.
But First: Should You Be Focusing on the Hardest Math Questions Right Now?
If you’re just getting started in your study prep, definitely stop and make some time to take a full practice test to gauge your current score level and percentile. The absolute best way to assess your current level is to simply take the ACT as if it were real, keeping strict timing and working straight through (we know—not the most thrilling way to spend four hours, but it will help tremendously in the long run). So print off one of the free ACT practice tests available online and then sit down to take it all at once.
Once you’ve got a good idea of your current level and percentile ranking, you can set milestones and goals for your ultimate ACT score. If you’re currently scoring in the 0-16 or 17-24 range, your best best is to first check out our guides on using the key math strategies of plugging in numbers and plugging in answers to help get your score up to where you want it to. Only once you've practiced and successfully improved your scores on questions 1-40 should you start in trying to tackle the most difficult math problems on the test.
If, however, you are already scoring a 25 or above and want to test your mettle for the real ACT, then definitely proceed to the rest of this guide. If you’re aiming for perfect (or close to), then you’ll need to know what the most difficult ACT math questions look like and how to solve them. And luckily, that’s exactly what we’re here for.

Anne made a recipe for miniature bread loaves that called for StartFraction 7 Over 8 EndFraction of a cup of whole-wheat flour. If the recipe made 7 equal-sized loaves of bread, how many cups of whole-wheat flour did each loaf contain? StartFraction 1 Over 8 EndFraction of a cup StartFraction 1 Over 7 EndFraction of a cup StartFraction 8 Over 49 EndFraction of a cup StartFraction 49 Over 8 EndFraction cups
Answer:
1/8
Step-by-step explanation:
So if the entire recipe makes 7 loaves and calls for 7/8 of a cup, you would need to split the 7/8 cups flour into 7. 7/8 ÷ 7=1/8.
Option A: 1/8 of a cup

Find the value of x and the value of y.
A. X-4, 7-8
B. x - 7,7=43
C. x = 4√3, 7-72
D. x=753, y = 4√2
Answer:
[tex]x= 7, y=4\sqrt{2}[/tex]
Correct option B.
Step-by-step explanation:
The diagram shows a trapezoid with a base angle of 45° and the other base angle of 90°.
We have completed the diagram to draw a perpendicular line over the base of height h=4. A triangle is formed with an angle of 45°.
Recall a right triangle with angles of 45° is isosceles, thus the base and the height are h=4. Please check the diagram below.
For that triangle, we apply Pythagora's Theorem:
[tex]y^2=4^2+4^2=2*4^2[/tex]
Thus:
[tex]y=\sqrt{2*4^4}=4\sqrt{2}[/tex]
[tex]y=4\sqrt{2}[/tex]
The base of the trapezoid x is h + 3 = 7
Thus:
[tex]\mathbf{x= 7, y=4\sqrt{2}}[/tex]
Correct option B.

A recent survey revealed that for every 13 people who prefer football, 7 people prefer basketball. There are 154 people at an event who prefer basketball. How many prefer football?
Answer:
286
Step-by-step explanation:
Given that:
For every 13 people who prefer football ; 7 prefer basket ball
At an event;
Number who prefer basketball = 154
Number who prefer football :
[(Total who prefer basketball) ÷ 7] * 13
(154 / 7) * 13
= 22 * 13
= 286
