Answer:
C
Step-by-step explanation:
3/4 + 6/10
Find a common denominator and find what you multiply to each denominator to get that number and multiply the numerator by the same amount
(3/4 * 5/5) + (6/10 * 2/2)=
15/20 + 12/20
Then add
15/20 + 12/20= 27/20
Then finally convert to mixed number
27/20 = 1 7/20
Answer:
a, (x-3/7)=2/3(3/2x-9/14), and c, 12.3x – 18 = 3(–6 + 4.1x).
Step-by-step explanation:
i just answered that question
Assuming that their exam success is independent then
P(both fail) = 1/4 x 2/5 = 2/20 or 1/10
Answer:
(A) 509.78
We need to move the decimal point after the first non-zero digit
So,
=> 5.0978 × 10² (Since the decimal point is moved two places to the left)
(B) 0.0289
Again after the first non-zero digit:
So, it becomes:
=> 2.89 × 10⁻² (Since the decimal point is moved 2 places to the right so it will be negative also)
