Answer:
- free throws: 136
- 2-point: 174
- 3-point: 121
Step-by-step explanation:
Let x represent the number of 2-point field goals Rebecca made. Then the number of 3-point field goals can be represented by t, where ...
x = 2t -68 ⇒ t = (x +68)/2 . . . . . number of 3-point field goals
The number of free throws made was x -38.
Rebecca's total point count was ...
1(x -38) +2x +3(x +68)/2 = 847
9/2x +64 = 847
9/2x = 783
x = (2/9)(783) = 174
x -38 = 136
(x +68)/2 = 121
Rebecca made 136 free throws, 174 2-point field goals, 121 3-point field goals.

Part 1. Here is my example of a real life scenario that describes what is happening. Let us say, I have 2 cookies and the bottle of milk costs 11 dollars, and 3 cookies and 4 bottles of milk cost 24 dollars.
Part 2.
y=11-2x
3x+4(11-2x)=24
3x+44-8x=24
-5x=-20
x=4
y=11-8
y=3
Therefore, each cookie costs 4 dollars, and a bottle of milk costs 3 dollars.
Hope this answer helps. Let me know if you need more help next time.
Answers
you'll get 4x+2x²=x+1
simplify further 2x²+3x-1
this one looks like a quadratic equation.
Thus, this is not a linear equation,
It's not linear. It's quadratic.

Final answer:
In triangle STU, the possible values for ∠S, derived by using the law of sines, are approximately 10.2° and 169.8°.
Explanation:
The student wants to find all possible values of ∠S in ΔSTU, s=1.6 cm, u = 9.5 cm and ∠U=24°. This is a problem involving the laws of sines and cosines in trigonometry. By using the law of sines, we can find ∠S = sin⁻¹ ((sin U * s) / u) ≈ 10.2° or 169.8° (since sinx is positive in both the 1st and 2nd quadrants). It is important to note that ∠S and ∠U are not complimentary angles in a right triangle, therefore, both possible values of ∠S are valid if they meet the condition that the sum of ∠S, ∠T and ∠U should be equal to 180° in ΔSTU.

Answer:
8 • 7 – 4 = 9 • 5 - 7.
Step-by-step explanation:
Given : 8 • 7 – 4 = ___________
To find : Which expression forms an equation with the given expression.
Solution : We have given 8 • 7 – 4 = ___________
First we solve the product
56 - 4.
52
Now we will check the 9 • 5 + 7
Solve the product 45 + 7 = 52.
So, the 8 • 7 – 4 = 9 • 5 - 7
Therefore, 8 • 7 – 4 = 9 • 5 - 7.
9*5=45 +7=52
