3[w-5]=[2w+10] thank you

amm1812

Answer:

$w=25$

Step-by-step explanation:

So we have the equation (I'm assuming the brackets are synonymous with parentheses):

$3(w-5)=(2w+10)$

Distribute the left:

$3w-15=2w+10$

Add 15 to both sides:

$3w=2w+25$

Subtract 2w from both sides:

$w=25$

And we're done!

Edit: Typo

Katie Made a scale drawing of a restaurant in real life the restaurant kitchen is 12 m wide it is 36 mm wide in the drawing what

Alex73 [517]

Answer:

Scale : 1 mm = $\frac{1}{3}\ m$

Scale : 3 mm = 1 m

Step-by-step explanation:

Let the scale used be 1 mm = 'x' m

Given:

Actual width of kitchen is 12 m.

Length used by Kate in drawing is 36 mm.

So, 36 mm in drawing is equivalent to 12 m in actual.

Therefore, 1 mm in drawing is equivalent to 'x' m in actual.

Taking proportions and solving by cross multiplication, we get

$\frac{36}{12}=\frac{1}{x}\\36x=12\\x=\frac{12}{36}\\x=\frac{1}{3}\ m$

Therefore, 1 mm in drawing is equal to $\frac{1}{3}\ m$ in actual.

Scale : 1 mm = $\frac{1}{3}\ m$

Scale : 3 mm = 1 m
