Answer: 8x+12
Distribute the 4. So, 4(2x)+4(3). Then you end up with 8x+12.
The answer is 10.
4 a + 5 b when a = 4 and b = - 1.2
Answer:
x=3/7
Step-by-step explanation:
x+4 5/7 = 12x
4 5/7 = 11x
x = 3/7
To solve for P(QIR) we use the formula:
P(QIR)=[P(Q∩R)]/P(R)
But from the diagram:
P(Q∩R)=3/22
P(R)=7/22
hence
P(QIR)=3/22÷7/22=3/7
