Answer:
x=1
Step-by-step explanation:
1) 6x-5y=5
2) 3x+5y=4
ets perform the following operation
1) +2), This leads to the following equation:
6x+3x-5y+5y=5+4
From where we obtain the solution for x
9x=9
x=1
Answer:
There are 10 counters in the bag and you want the 4
As their is only one for the probability is
1/10
There are now 9 counters left in the bag.
You only want the even ones , which are 2 6 8 and 10 ( four has been taken out)
There are only four even counters in the bag of nine counters so the probability is
4/9
As you want both of these to occur, you need to multiply them
1/10 x 4/9 = 49/90
Step-by-step explanation:
For this case we have the following expression:

Rewriting the expression we have:
1) First we subtract the numbers within the parenthesis:

2) Then, we solve the exponents:

3) Then, multiplication:

4) Finally, the addition of numbers is made:

Answer:
the value of the expression is:
B: 29
6) a
7) a
8) d
9) d
