Answer:

\boxed{-\frac{7}{12} }

Step-by-step explanation:

-1\frac{1}{3} +\frac{3}{4}

→ Make both denominators the same

-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}

→ Convert mixed number into improper fraction

-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}

→ Do the -16 + 9 and leave 12 as the denominator

-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}=-\frac{7}{12}

Michael paid $10.11 for a pair of jeans. This amount included a tax of 2%. What was the cost before tax?
djverab [1.8K]

Answer: $9.91

Step-by-step explanation: The correct answer is $9.91 for the jeans. This is calculated by divided the total paid ($10.11) by 1.02, which represents the cost of the jeans + the 2% interest. 10.11 / 1.02 = $9.91.

You can then double check you work by calculating the 2% interest rate of the jeans. $9.91 x 2% = $ .20. The total is $9.91 for the jeans plus $ .20 for the tax, for a total of $10.11, which is the amount in the original problem.

At 99% confidence, the critical value is z = 2.576.

The standard error is σ/√n = 5.4/√n.

Given the desired margin of error is 0.65:

0.65 = 2.576 × 5.4/√n

What is the value of x?<br><br><br><br> Enter your answer in the box.
ArbitrLikvidat [17]

Answer:

50 =x

Step-by-step explanation:

The two angles are vertical angles, so they are equal

2 (x+10) = 3x-30

Distribute the 2

2x+20 = 3x-30

Subtract 2x from each side

2x-2x+20 = 3x-2x-30

20 = x-30

Add 30 to each side

20+30 = x-30+30

50 =x
