X+y=24 so we can say
x=24-y making 3x+5y=100 become
3(24-y)+5y=100
72-3y+5y=100
72+2y=100
2y=28
y=14, since x=24-y
x=10
So there are 10 3-point questions and 14 5-point questions.
Answer: To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical. If the indices or radicands are not the same, then you can not add or subtract the radicals.
If two integers product is:
- <u>Positive:</u> then the integers were both negative or both positive (same sign)
- <u>Negative:</u> then the integers consisted of one negative and one positive (opposite signs)
Answer:
(2, 14), (5, 12), (8, 10), (11, 8), (14, 6)
Step-by-step explanation:
Lets do the math for Pattern A:
2 + 3 = 5
5 + 3 = 8
8 + 3 = 11
11 + 3 = 14
Lets do the math for Pattern B:
14 - 2 = 12
12 - 2 = 10
10 - 2 = 8
8 - 2 = 6
6 - 2 = 4
Answer:
144 in cubed
Step-by-step explanation:
you do 8 * 9 * 2 to find area and then by doing that you get 144
