Answer:
1.41
Step-by-step explanation:
Tenths are the first number to the right of the decimal
Hundredths are the second number to the right of the decimal.
So square root of 2 to the nearest hundredth would be
1.41
The third digit to the right of the decimal is a 4. So it is less than five, the digit in the hundredths place is not increased. If it was 5 or more, then the answer would be 1.42.
1. Answer is x = 1
Explanation: Rearrange terms
-22 + 8c = 28x - 42
Add 22 to both sides of the equation
8x - 22 = 28x - 42
8x - 22 + 22 = 28x - 42 + 22
Simplify
8x = 28x - 20
Subtract 28x from both sides of the equation
8x = 28x - 20
8x - 28x = 28x - 20 - 28x
Simplify
-20x = -20
Divide both sides of the equation by the same term
-20x/-20 = -20/-20
2. Answer is x = -8
Rearrange terms
-11x - 2 = 6 - 10x
-11x - 2 = -10x + 6
Add 2 to both sides of the equation
-11x - 2 = -10x + 6
-11x - 2 + 2 = -10x + 6 + 2
Simplify
-11x = -10x + 8
Add 10x to both sides of the equation
-11x = -10x + 8
-11x + 10x = -10x + 8 + 10x
Simplify
-x = 8
Divide both sides of the equation
-x = 8
-x/-1 = 8/-1
Simplify
x = -8
3. Answer is x = 7
Rearrange terms
4x + 8 = -13 + 7x
Subtract 8 from both sides of the equation
4x + 8 - 8 = 7x - 13 - 8
Simplify
4x = 7x - 21
Subtract 7x from both sides of the equation
4x = 7x - 21
4x - 7x = 7x - 21 - 7x
Simplify
-3x = -21
Divide from both sides
-3x = -21
-3x/-3 = -21/-3
answer is x = 7
4. Answer is x = -15
Subtract 8 from both sides
2x + 8 = x - 7
2x + 8 - 8 = x - 7 -8
Simplify
2x = x - 15
Subtract x from both sides of the equation
2x = x - 15
2x - x = x- 15 - x
Simplify
x = -15
Tried to be detailed lol hope this helps!
Answer:
Total number of vial = 44 vial (Approx.)
Step-by-step explanation:
Given:
Total amount of medicine in a case = 160 ounces
Amount of medicine in each vial = 11 / 3 oz
Find:
Total number of vial
Computation:
Total number of vial = [Total amount of medicine in a case / Amount of medicine in each vial]
Total number of vial = 160 / [11/3]
Total number of vial = 160 / 3.667
Total number of vial = 43.63
Total number of vial = 44 vial (Approx.)
