Answer:
x = 2.5 or -0.8
Step-by-step explanation:
Here, we are to use completing the square method to solve for the values of x
Firstly, we divide through by 4
= x^2 -7/4x -2 = 0
Now, we move the two term to the right hand side
x^2 -7/4x = 2
Now, we divide the coefficient of x by 2 and square it;
That would be;
(-7/4 * 1/2)^2 = 49/64
we now add this value to both sides of the equation
x^2 -7/4x + 49/64 = 2 + 49/64
The right hand side can be rewritten as;
(x-7/8)^2 = 177/64
taking the square root of both sides
x-7/8 = √(177/64)
x = 7/8 ± √(177/64)
x = 7/8 + √(177/74) or 7/8 - √(177/64)
= x = 2.53802 or -0.788017
Which to the nearest tenth is
x = 2.5 or -0.8
Answer:
40%
Step-by-step explanation:
First, you have to divide 90 by 10 and get 9 and now figure out how many times you can divide 36 to get nine, four times. Next, now multiply 4 by ten and that is your percentage.
16 ounces = 1 pound so 16 x 8 = 128 so 128 ounces is your answer
Let the consecutive even integers be x and (x+2).
x + (x + 2) = 106
2x + 2 = 106
2x = 104
x = 52
Thus the two integers are 52 and 54.
