Answer:
(10/3, 2/3)
Step-by-step explanation:
You may find it easier to write these two equations x+y=4 2x-y=6 in a column:
x+y=4
2x-y=6
Adding these together will eliminate y:
3x = 10. Then x = 10/3.
Substituting 10/3 for x in the first equation results in:
10/3 + y = 4
Clear fractions by multiplying all three terms by 3:
10 + 3y = 12
Then 3y = 2, and y = 2/3.
The solution is (10/3, 2/3)
Answer:
The answer is option 1 , 2 and 3 or A , B and C
Step-by-step explanation:
Taking a sqrt=taking a 1/2 power, so when you take a power of a power, you multiply them. So you’re finding 10.3^(3/2).
=33.056

Answer:
Sue has a 12% chance of choosing a black dress and a gold necklace (as a fraction: 3/25, and as a decimal: 0.12).
Step-by-step explanation:
To find the probability of two separate events both occurring (in this case, selecting a black dress and a gold necklace), the probabilities are multiplied usually as fractions or decimals.
<u>As fractions:</u>
40% = 4/10
30% = 3/10
4/10 * 3/10 = 12/100 = 3/25, 0.12, or 12%
<u>As decimals:</u>
40% = 0.4
30% = 0.3
0.4 * 0.3 = 0.12 = 3/25, 0.12, or 12%
