(2/5)k + (1/10)k = (1/2)k - 1
0.4k + 0.1k = 0.5k - 1
We need to solve for k.

Subtract 0.4k from both sides
0.4k - 0.4k + 0.1k = 0.5k - 0.4k - 1
0.1k = 0.1k - 1

Subtract 0.1k from both sides:
0.1k - 0.1k = 0.1k - 0.1k - 1
0 = -1

Impossible. The equation has no solution.

Mary Ann needs 3/7 cup of sugar to bake a cake she has 3/5 cup does she have enough to bake the cake yes or no
IrinaVladis [17]

Answer:

Mary Ann does have enough sugar

Step-by-step explanation:

3/5 is greater than 3/7 which means that she does have enough sugar. This is because the denominator 5 is smaller than the denominator 7, and since they have the same numerator, the fraction with the smaller denominator is greater.

I think A, C, D are right because of the 12 pairs of heels, 6 are black (6/12) That means half of them could be chosen and be black (0.5). Another way to write 0.5 is as a percentage, 50%.

Solve five and three sixths minus two and one third.
CaHeK987 [17]

Answer:

3 3/18

Step-by-step explanation:

5 3/6-2 1/3

We first need to turn our mixed numbers into fractions by multiplying the while number by the denominator, then adding the numerator. When we do this, 5 3/6 turns into 33/6 and 2 1/3 turns into 7/3. Now we have this:

33/6-7/3

Now we need to find the Least common multiple of the denominators in order to find our common denominator, which in this case is 6. 33/6 already has a denominator of 6, so we do not need to do anything to it. To give a denominator of 6 to 7/3, however, we must multiply by 2, giving us this:

33/6-14/6

Now we can subtract the numerators.

19/6

To turn this back into a mixed number, we divide 19 by 6, which gives us 3 with a remainder of 1. Therefore, our answer is 3 1/6. This is an equivalent fraction to the fourth answer, 3 3/18.
