Answer: 74
<u>Step-by-step explanation:</u>
Homework + Quiz + Test + Final Exam = 70
67(10%) + 62(15%) + 71(50%) + x(25%) = 70
6.7 + 9.3 + 35.5 + 0.25x = 70
51.5 + 0.25x = 70
0.25x = 18.5
x = 74
The minimum score is 74.
If y=15 then x=45 because 45 minus 15 is 30

Answer:
To find out the first three terms of 3n - 2 substitute 1 ,2 and 3 into the equation.
so the three terms a
3(1)-2=1
3(2)-2=6-2=4
3(3)-2=9-2=7
As you can see the sequence goes up in 1,4 and 7.To find out the 10th term you also substitute 10 into the equation so 3(9)-2=18-2=16
so 16 is the tenth term
Hope this helped!
Answer:
3): 14
Step-by-step explanation:
The problem states that ABC and DEF are similar. Therefore, dsue to similar triangles, we have 7x/7=4/x, so x^2=4. Therefore, x=2 (because x cannot be negative). Therefore, AB = 7x = 7*2=14
