Answer:
28,882.87
Step-by-step explanation:
20,157.50
+ 8,725.37
28,882.87
Answer:
Step 1-Write an equation, letting x represent Kareem’s age:
(x + 3) + x + 2 x = 33
Step 2-Solve the equation:
(x + 3) + x + 2 x = 33. 3 + 4 x = 33. 4 x = 30. x = 7 1/2.
Step 3-Sadie is 10 1/2, Kareem is 7 1/2, and Nadra is 3 3/4.
Which corrects the student’s first error?
1. In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x +1/2x = 33.
2. In Step 2, the student should have added 3 on both sides of the equation to find a solution of x = 9.
3. In Step 3, the solution represents Sadie’s age. Therefore, Sadie is 7 1/2, Kareem is 4 1/2, and Nadra is 2 1/4.
4. In Step 3, Nadra’s age is the difference between 33 and Sadie’s and Kareem’s ages, so Nadra is 15.
T(x) is the only function up above where the highest degree is a 2, which is what a quadratic function is: a function of degree 2
Answer:
30 and 6
Explanation:
Let the numbers be x and y. Then
<span>x+y=36</span>
<span>x−y=24</span>
Adding the two equations together gives
<span>2x=60</span>
<span>∴x=30</span>
Substituting this back into either of the equations gives <span>y=<span>6</span></span>
Ur answer should be 28 hopefully I’m not wrong
