sesenic [268]3 years ago
6 0

Answer:

2 19/5

Step-by-step explanation:

4 7/9 ÷ 1 7/12

<em>start by turning them into improper fraction by multiplying the denominator to the whole number and adding the product to the numerator , you will get :</em>

42/9 ÷ 17/12

42/9 * 12/17 <em>( reciprocal )</em>

42/3 * 4/17 <em>(9 and 12 can be cut smaller because both are in 3's table)</em>

= <u>172/51</u>

turn this into mixed fraction by -

<em>Divide the numerator by the denominator. </em>

<em>Write down the whole number answer </em>

<em>Then write down any remainder above the denominator</em>

you will get = <u>2 19/5</u>

Matthew has 2 dozen eggs. He uses 3/4 of the first dozen and 5/6 of the second dozen for baking.
madreJ [45]

Answer:

5 eggs.

Step-by-step explanation:

Well, 3/4 of 12 is 9 and 5/6 of 12 is 10. So, 12 - 9 = 3 and 12 - 10 = 2

Therefore, Matthew has 5 eggs left over.

I hope I helped ^^

Liam says - (5/12) is equivalent to 5/-12. Explain if Liam is correct by completing the statements below.
makkiz [27]

A positive number divided by a positive number results in a negative quotient, and it's opposite is always positive. The fraction 5/-12 can be described as a positive number divided by a negative number, which always results in a negative quotient. The fractions have different value, so Liam is not correct.

In exercises 9 to 12 all solutions to the equations​
natita [175]

Answer:

12b. 28 = x

12a. -7 = x

11b. -6 = x

11a. 9 = x

10b. UNDEFINED

10a. -⅕ = x

9b. <em>i</em> = x

9a. ±3 = x

Step-by-step explanation:

12. Cube both sides of both equations, then solve for <em>x</em>:

12b. \: 3 =  \sqrt[3]{x - 1} >> 27 = x - 1 \\  \\ 28 = x \\  \\  12a. \: -2 =  \sqrt[3]{x - 1} >>  -8 = x - 1 \\  \\  -7 = x

11. Square both sides of both equations, then solve for <em>x</em>:

11b. \: 1 =  \sqrt{x + 7} >> 1 = x + 7 \\  \\  -6 = x \\  \\ 11a. \: 4 =  \sqrt{x + 7} >> 16 = x + 7 \\  \\ 9 = x

10. Dividing is the same as multiplying by the <em>multiplicative</em><em> </em><em>inverse</em><em> </em>of another term:

10a. \:  -5 = \frac{1}{x} >> -5 =  {x}^{ -1} \\  \\  -\frac{1}{5} = x

* ⁻¹ indicates the <em>multiplicative</em><em> </em><em>inverse</em><em> </em>of -⅕, which is -5. Then there is 1⁄0, which is undefined.

9.

9b. \:  -6 = {x}^{2} - 5

+ 5 + 5

____________________

-1 = x²

i = x

According to the Complex Number System, the <em>iota</em><em> </em>symbol can be either <em>complex</em> or <em>real</em>:

\sqrt{-1} = i \\  -1 =  {i}^{2} \\ -i =  {i}^{3} \\ 1 = {i}^{4}

I am joyous to assist you anytime.
