2/3x+3=6
2/3x=3
x= 3*3/2
x=9/2=4.5
(Mark me the brainliest if this was helpful)
Answer:
Part A: Let c = the cost of each candy bar
3 + 8c = 43
8c = 40
Part B: c = $5.00
Step-by-step explanation:
As a fraction, the exact answer is 5/6
In decimal form, the approximate answer is 0.8333
To get this answer, note how there are 5 ways to roll something that isn't a three (1,2,4,5,6) out of 6 ways total (1,2,3,4,5,6)
So you simply divide the two values to get 5/6 = 0.8333
I hope this helps you
4/5-1/3
(4.3/5.3)-(1.5/3.5)
12/15-5/15
7/15
sqrt (5x - 9) - 1 = x
sqrt(5x - 9) = x + 1
Square both sides:_
5x - 9 = x^2 + 2x + 1
x^2 - 3x + 10 = 0
(x - 5)(x + 2) = 0
x = 5 or -2.
Lets look for for any extraneous solutions:-
x = 5 ; sqrt (5*5-9) - 1 = sqrt16 - 1 = 3 and x = 3 (right hand side of equation)
so x = 5 is a solution
x = -2: sqrt(5*-2 - 9) - 1 = sqrt (-19) - 1 and x = -2 so this is extraneous
Answer:- One solution x = 5
