P = 2a + b
10= 2a + 3
2a = 10-3
a = 7/2 = 3.5
Therefore, numerical value of a is 3.5
Expand the brackets first
5(wx-v) = 9(x + v)
5wx - 5v = 9x + 9v
Get all x's on one side and everything on on the other side
9x - 5wx = 9v + 5v
factorise out the x
x(9-5w) = 14v
then divide by 9-5w
x = 14v/(9-5w)
Answer:
i am sorry i need points i don't have an answer
Step-by-step explanation:
First you want to change the fractions to the same denominator
3/4 = 9/12 and 2/3 = 8/12
then you put it in ratio form...
the answer is 9:8
