Answer:
y = -29/19 and x = -44/19
Step-by-step explanation:
3x + 2y = -10 multiply by -2 ⇔ -6x - 4y = 20
2x - 5y = 3 multiply by 3 ⇔ <u> 6x - 15y = 9 </u>
Add the two equation -19y = 29
y = -29/19
Use equation one and solve for x
3x + 2(-29/19) = -10
3x - 58/19 = -10
3x = -10 + 58/19
3x = -190/19 + 58/19
3x = (-190 + 58)/19
3x = -132/19
x = - 132/ 19 ÷3
x = -44/19
Answer: 1/13
Step-by-step explanation:
There are 4 twos in a pack of 52 cards. So the probability is 4/52 = 1/13
There are 4 threes in a pack of 52 cards. So the probability is again 4/52 = 1/13
So the probability that a 2 or 3 will be drawn is
1/13 + 1/13 = 2/26 = 1/13

Answer: w is equal to the sum of angles x and y. (W=x+y)
Step-by-step explanation:
The exterior angle of a triangle (in this case w) is equal to the sum of the two remote interior angles of the triangle (in this case angles x and y)
