Answer: A 65
Explanation: using PEMDAS you substitute 4 in for k and add 9+4 because it’s in parenthesis. Then you multiply the 13 you get from that by 5 and get 65.

2 1/3 divided by 2/5

elena-14-01-66 [18.8K]

Answer:

$5 \frac{5}{6}$

Step-by-step explanation:

First let's turn 2 1/3 into an improper fraction. Multiply the whole number by the denominator, and add the product to the numerator.

2 × 3 = 6

6 + 1 = 7

The new fraction is 7/3

$\frac{7}{3} \div \frac{2}{5} = \frac{7}{3} \times \frac{5}{2}$

Divide by multiplying the first fraction by the reciprocal of the second fraction. Then multiply straight across.

$\frac{7 \times 5 = 35}{3 \times 2 =6 \: \: }$

The product is 35/6

Let's divide 35 ÷ 6 = 5.83

So we know the new whole number is 5.

5 × 6 = 30, 35 - 30 = 5, the new numerator.

$5 \frac{5}{6}$

The new fraction is 5 5/6.

How do you figure this out?

algol [13]

Let the red cat be represented by x.

Let the yellow cat be represented by y.

Let the white cat be represented by z.

Which means :

$\tt (1) \: \frac{4}{5} (20x - 5)$

$\tt = \frac{4}{5} \times 20x - \frac {4 }{5} \times 5$

$\tt= \frac{80x}{5} - \frac{20}{5}$

$\tt = 16x - 14$

Thus, the first statement is correct.

$\tt(2) \: \frac{3}{5} ( \frac{1}{3} z - 10)$

$\tt = \frac{3}{5} \times \frac{1}{3} z - \frac{3}{5} \times 10$

$\tt = \frac{3}{15} z- \frac{30}{5}$

$\tt = \frac{1}{5} z - 6$

Thus, the second statement is a lie.

$\tt(3) \: \frac{1}{9} ( - 9y - 27x)$

$\tt= \frac{1}{9} \times - 9y - \frac{1}{9} \times 27x$

$\tt = \frac{ - 9}{ \: \: 9} y - \frac{27}{9} x$

$\tt = (- y) - 3x$

Thus, the third statement is correct.

Therefore, <u>the second one is a lie</u>.
