Answer: a) -27, b) 35, c) 14

Step-by-step explanation:

a) When a positive number is multiplied by a negative number, your answer is negative, and since we know that 9 × 3 = 27, and that this figure has to be negative (since 9 is negative), the answer is -27.

b) Multiplying two negative numbers gives a positive number, and since 7 × 5 = 35, the answer is positive 35 (as both 7 and 5 in the original question are negative).

c) Follows just like b.

Order from least to greatest 61% , 0.605, 3/5, 59%
krek1111 [17]
So you'd have to convert all of the values to one form, and I find it easiest to do it in decimals. 61% would be 0.61, 0.605 stays the same, 3/5 would be 0.6, and 59% would be 0.59. Now you can order them:
0.59, 0.6, 0.605, 0.61
You have to convert them back to their original form, however, so your answer would be
59%, 3/5, 0.605, 61%
I hope this helps!

What’s the answer to 3x/x+5+7/x+5
uranmaximum [27]
Ambiguous expression.  I think you meant:
                                 3x + 7
<span>3x/(x+5)+7/(x+5) = --------------
                                  x+5

There's no "answer."  All you can do here is to combine the terms and simpify the resulting sum.
