Nady [450]

Answer: 4\dfrac{1}{8}\ \text{bags}

Step-by-step explanation:

Given

Jasper lawn is three-fourth of an acre

1 acre of land requires 5\frac{1}{2} bags

convert mixed numeral to fraction

\Rightarrow 5\dfrac{1}{2}=\dfrac{11}{2}

\therefore 1\ \text{acre}\equiv\dfrac{11}{2}\ \text{bags}\\\\\Rightarrow \dfrac{3}{4}\ \text{acre}\equiv \dfrac{11}{2}\times \dfrac{3}{4}=\dfrac{33}{8}\ \text{bags}

\Rightarrow \dfrac{33}{8}\ \text{bags}=4\dfrac{1}{8}\ \text{bags}

A table measures x+4 inches long and 5x+12 inches wide. What is the perimeter of the table?
tangare [24]

Answer:

P = 12x +32

Step-by-step explanation:

The perimeter is found by using the formula

P =2(l+w)

We know the length and the width

P = 2(x+4 + 5x+12)

Combine like terms

P = 2(6x+16)

Distribute

P = 12x +32
