Answer:
11/12
Step-by-step explanation:
(1 1/10)/(1 1/5) = 1.1/1.2 = 11/12
__
You can also work this using improper fractions:
(1 1/10)/(1 1/5) = (11/10)/(6/5) = 11/10×5/6 = (11×5)/(6×10)
= (11×5)/(6×2×5) = 11/(6×2) = 11/12
Answer:
x ∈ All real numbers
Step-by-step explanation:
When the distributive property is applied to the left side, the parentheses can be eliminated and the equation becomes ...
-2x -6 = -2x -6
This is true for all possible values of x, "all real numbers".
Answer:
80kg
Step-by-step explanation:
100 + 10 = 110% (Percentage of gained weight)
110% = 88000
1% = 88000 ÷ 110 = 800
100% = 800 x 100 = 80000
She made her mistake at the first step. To simplify a radical, you would find two numbers that multiply by each other to get your original number (under the radical)
and have one of the number be a perfect square.
Her reasoning is wrong because 10*10 is not

. Had she been correct, her answer should have been able to be squared to equal

In other words, she should have done

(We used 25 because 25 is a perfect square, 5*5=25).
