Answer:
1.5 or 3/2
Step-by-step explanation:
You multiplied the hamburger rolls price by 10 but there are 6 of them in 1 package. The answer would be $4.70.
0.85×2= 1.70
1.00×3= 3.00
1.70+3.00= 4.70
I think what you meant was
(2x - 5)² = 11 -- (1)
Square root both sides of (1), i.e.
√(2x - 5)² = ± √11 -- (2)
From (2), we have
2x - 5 = ± √11 -- (3)
By adding 5 to both sides in (3), we have
2x = 5 ± √11 -- (4)
Divide both sides of (4) by 2, and we obtain
x = (5 ± √11)/2 -- (5)
From (5), the solution set of (1) is
x = (5 + √11)/2, (5 - √11)/2 ...Ans.
