Answer:

1/15

Step-by-step explanation:

(5/7 - 1). [2/3 + (1/6 - 1/9), 18/5 + 1/15] - (2/7 + 1/3). (-7/13)

Use order of operations; PEMDAS.

Start with the inner parentheses:-

= (5/7 - 1). [2/3 + 1/18. 18/5+ 1/15] - (2/7 + 1/3). (-7/13). Now the other parentheses:-

= (-2/7). ( 2/3 + 1/5 + 1/15) - (13/21).(-7/13)

= -2/7 . 14/15 + 7/21

= -2/7 . 14/15 + 1/3

= -4/15 + 1/3

= 1/15 (answer)

Answer:

(5/7 - 1) * (2/3 + (1/6 - 1/9) * 18/5 + 1/15) - (2/7 + 1/3) * (-7/13)

= (5/7 - 7/7) * (2/3 + (3/18 - 2/18) * 18/5 + 1/15) - (6/21 + 7/21) * (-7/13)

= (-2/7) * (2/3 + 1/18 * 18/5 + 1/15) - 13/21 * (-7/13)

= (-2/7) * (2/3 + 1/5 + 1/15) + 7/21

= (-2/7) * (10/15 + 3/15 + 1/15) + 1/3

= (-2/7) * 14/15 + 1/3

= -4/15 + 1/3

= -4/15 + 5/15

= 1/15

A student wants to graph the function

pishuonlain [190]

Answer: x= -3/4y+6

Step-by-step explanation: Let's solve for x.

4x+3y=24

Step 1: Add -3y to both sides.

4x+3y+−3y=24+−3y

4x=−3y+24

Step 2: Divide both sides by 4.

4x/4=−3y+24/4

To make banana bread, Colin uses 3/4 of a cup of brown for every 2 cups of flour. How much brown sugar should Colin use to make

Lelechka [254]

$\frac{3}{8}$ cups of brown sugar needed for only 1 cup of flour

<em><u>Solution:</u></em>

To make banana bread, Colin uses $\frac{3}{4}$ of a cup of brown for every 2 cups of flour

To find: Amount of brown sugar should Colin use to make a small batch with only 1 cup of flour

Let "x" be the amount of brown sugar needed for only 1 cup of flour

From given information,

$\text{ 2 cups of flour } = \frac{3}{4} \text{ cup of brown sugar }$

$\text{1 cup of flour } = \text{ x cup of brown sugar }$

This forms a proportion and we can solve the sum by cross multiplying

$1 \times \frac{3}{4} = 2 \times x\\\\x = \frac{3}{8}$

Thus $\frac{3}{8}$ cups of brown sugar needed for only 1 cup of flour

antiseptic1488 [7]

Answer:

a) will definitely be an odd number

Step-by-step explanation:

4^n is always even (when you multiply even and even number, the product is always even)

when you add one to even number, the sum is always odd

so 4^n +1 is odd.
