Answer:

x = 12.6

Step-by-step explanation:

When you have one fraction equated to another one, the means-extremes property allows you to cross multiply, as follows:

\frac{a}{b} = \frac{c}{d}

can be rewritten as:

a*d = c*b

For this case:

\frac{5}{7} = \frac{9}{x}

5*x = 7*9

x = 63/5

x = 12.6

1) What is the length of the garden in this blueprint?<br> 1”=4 feet <br> 1/4
patriot [66]

Answer:

Area is the measure of the amount of surface covered by something. Area formulas for different shapes are sometimes different, but for the most part, area is calculated by multiplying length times width. This is used when calculating area of squares and rectangles. Once you have the number answer to the problem, you need to figure out the units. When calculating area, you will take the units given in the problem (feet, yards, etc) and square them, so your unit measure would be in square feet (ft.2) (or whatever measure they gave you).

Find the measure of the indicated angles below.Drag the points to show the measure of the four angles
horrorfan [7]
<h2>Answer</h2>

A. Angle E = 113°

B. x = 16°

<h2>Explain</h2>

<u>Number A</u>

92 + 70 + 85 + ? = 360

162 + 85 + ? = 360

247 + ? = 360

? = 360 - 247

? = 113°

<u>Number B</u>

108 + 84 + ( x + 30 ) + ( 2x + 18 ) = 360

(180 + 84 + 30 + 18) + (x + 2x) = 360

312 + 3x = 360

3x = 360 - 312

3x = 48

x = 48/3

x = 16°
