Answer:
Step-by-step explanation:
4 - 2(x + 7) = 3(x + 5) Remove the brackets.
4 - 2x - 14 = 3x + 15 Combine
-2x- 10 = 3x + 15 Add 2x to both sides
- 10 = 2x + 3x + 15 Combine
-10 = 5x + 15 Subtract 15 from both sides
-10 - 15 = 5x Combine the left side
-25 = 5x Divide by 5
-25/5 = 5x/5
x = - 5

Answer:
A. 1/2.
B. 15/26.
Step-by-step explanation:
Note when you have an 'OR' in the statement we <u>add </u>the probabilities.
A . Club or a diamond . There are 13 clubs and 13 diamonds so
The Required Probability = 13/52 + 13/52
= 1/4 + 1/4 = 1/2.
B. There are 4 jacks and 26 black cards.
The Required Probability = 4/52 + 26/52
= 1/13 + 1/2
= 2/26 + 13/26
= 15/26.
