Answer:
1) Antonio's statement
2) <A = 123
Step-by-step explanation:
1) Antonio's statement is incorrect. This is because the opposite angles of a quadrilateral add up to 180°. Erin was incorrect because the opposite angles of this quadrilateral are unequal.
2) 2x+7+5x-2 = 180° (opposite angles of quadrilateral)
Now
7x+5 = 180
7x = 175
x = 25
<A = 5x-2
= 5(25)-2
= 125-2
= 123
Answer:
X=3
Step-by-step explanation:
1-move the (9v) to the other side and change it to negative and it will be (13v-9v=12)
2-Collect like terms and it will be (4v=12)
3-Divide both sides on 4 and it will be (v=3)
Answer:
The probability of drawing a second red card, since the first card is red is 25/51
Step-by-step explanation:
The probability of drawing a second red card since the first Card is red is:
P (R2 | R1) = P (R2 and R1) / R1
So:
P (R2 | R1) = (25/102) / 1/2
P (R2 | R1) = 25/51
Therefore the correct option is option 2.
the probability of drawing a second red card, since the first card is red is 25/51
