6/8 divide by 8/12<br> A. 9/2<br><br><br> B. 8/9<br><br><br> C. 9/8<br><br><br> D. 9/32

Musya8 [376]

Answer:

C. 9/8

Step-by-step explanation:

$\frac{6}{8} \div \frac{8}{12}$

Use KCF which means Keep the first fraction, Change the second fraction by flipping it and change the division sign to a multiplication symbol:

$\frac{6}{8} \times \frac{12}{8}$

multiply the numerator together:

6 × 12 = 72

multiply the denominator together:

8 × 8 = 64

now the fraction is:

$\frac{72}{64}$

simplify further by dividing both numbers by 8:

72 ÷ 8 = 9

64 ÷ 8 = 8

so the fraction is 9/8

Two planes leave an airport at the same? time, one flying? east, the other flying west. the eastbound plane travels 90 mph slowe

Law Incorporation [45]

2x + 2(x-90) = 3480

2x + 2x - 180 = 3480

4x = 3660

x = 915 mph Plane 1 westbound

915-90 = 825 mph plane 2 eastbound

The rectangle below has an area of 12y^2+21y^5 The width of the rectangle is equal to the greatest common monomial factor of 12y

Luba_88 [7]

Answer:

Width = $3y^{2}$

Length = $4+7y^{3}$

Step-by-step explanation:

Area of the rectangle = $12y^{2}+21y^{5}$

Width of the rectangle is greatest common monomial factor of $12y^{2}$ and $21y^{5}$ . Monomial means consisting of a one term only. Terms in an algebraic expression are distinguished by symbols of addition and subtraction. So, in expression of Area there are 2 terms. Factorizing the expression of Area will give us the width and length of the rectangle as shown below:

$Area = 12y^{2}+21y^{5}\\\\ Area=3y^{2}(4+7y^{3})$

Since, Area of a rectangle is the product of its length and width, and the monomial factor represents the width, we can write:

Width = $3y^{2}$

Length = $4+7y^{3}$
