Anika [276]
The area is 120/(1/4) or 120 x 4 or 480 square inches
the width is 6/(1/2) or 6 x 2 or 12 inches
to find the length, divide the area by the width
480/12= 40

Missing term = –2xy

Solution:

Let us first find the quotient of -8x^2y^3 \div xy.

-8x^2y^3 \div xy=\frac{-8x^2y^3 }{xy}

                    =\frac{-8\times x\times x\times y\times y\times y}{xy}

Taking common term xy outside in the numerator.

                    =\frac{xy(-8\times x\times y\times y)}{xy}

Both xy in the numerator and denominator are cancelled.

                    =-8xy^2

Thus, the quotient of -8x^2y^3 \div xy is -8xy^2.

Given the quotient of -8x^2y^3 \div xy is same as the product  of 4xy and ____.

-8xy^2=4xy × missing term

Divide both sides by 4xy, we get

⇒ missing term = \frac{-8xy^2}{4xy}

Cancel the common terms in both numerator and denominator.

⇒ missing term = –2xy

Hence the missing term of the product is –2xy.

Malia is planting tomato and pepper plants in her garden each tomato plant t requires 6 square feet and each pepper plant p requ
Misha Larkins [42]

4p + 6t ≤ 150 inequality represents this situation

<h3><u>Solution:</u></h3>

Given that,

tomato plant is represented by "t"

pepper plant is represented by "p"

Malia's garden has an area of 150 square feet

Given that each tomato plant "t" requires 6 square feet of space

<em><u>So, the area required to plant "t" tomato plants</u></em>:

= t x ( Area required by 1 tomato plant)  = t x ( 6 sq ft)  = 6t

Each pepper plant p requires 4 square feet of space

<em><u>So, the area required to plant p pepper plants   </u></em>

= p x ( Area required by 1  pepper plant)   = p x ( 4 sq ft)  = 4p

Given that total area of garden = 150 square feet

area of "p" pepper plants + area of "t" tomato plants = 4p + 6t

<em><u>So, now according to the question: </u></em>

The area occupied by both plants must be less than or equal to total area of garden

Total area of both plants ≤ Total area of the garden

4p + 6t ≤ 150

Thus inequality is found
