Answer:

X=5/2

Step-by-step explanation:

1. subtract x from both sides, you now have 3x - 1/2 = 7

2. now you add 1/2 to both sides to get x by itself and you are left with 3x=7

4. divide by 3 on both sides to get x by itself

5. x=5/2

What is the actual height of the building shown in the model?

julsineya [31]

Answer:

The actual height is 150ft

Step-by-step explanation:

Given

$Width : Height = 2cm : 5cm$

$Actual\ width = 60ft$

Required

Determine the actual height

Substitute 60ft for width in: $Width : Height = 2cm : 5cm$

$60ft:Height =2cm:5cm$

Express as fraction

$\frac{60ft}{Height} =\frac{2cm}{5cm}$

$\frac{60ft}{Height} =\frac{2}{5}$

Make height the subject

$Height = \frac{5}{2} * 60ft$

$Height = 5 * 30ft$

$Height = 150ft$

Find the value of x in each case:

goblinko [34]

Answer:

x = 11

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ FEB and ∠ DEB are adjacent angles and supplementary, thus

∠ FEB = 180 - 4x , so

180 - 4x + x = 147, that is

180 - 3x = 147 ( subtract 180 from both sides )

- 3x = - 33 ( divide both sides by - 3 )

x = 11

HELP ASAP WILL GIVE BRAININST IF:

DiKsa [7]

Answer:

<em><u>slope is -7/8</u></em>

Step-by-step explanation:

first remember these to formulas:

$m= \frac{y2-y1}{x2-x1}$

and

$y-y1 = m(x-x1)$

now insert the points:

$\frac{-3-4}{3-(-5)}$ = -7/8

slope intercept form:

y - 4 = -7/8(x - (-5)

y - 4 = -7/8(x + 5)

y = -7x/8 - 3/8

Have a nice day!

and if you have a question or if I did anything wrong please tell me.
