Answer:

y = -2/3 + 18

Step-by-step explanation:

2x + 3y = 18 ----- here is the equation...

-2x - 2x ----- bring the 2x to the other side

3y = -2x + 18 ----- now you have to divide everything by 3 to get y by itself

y = -2/3 + 18 ----- Done!

Answer:

y= -2/3x + 6

Step-by-step explanation:

Subtract 2 from both sides of the Equation:

3y=18-2x

Divide each term by 3 and simplify:

y= - 2x/3 +6

Rewrite into slop-Intercept form;

y=2/3x+6

What is the new volume of a right square pyramid with a volume 180in.3 if the lengths of the sides of the base remain fixed but

garik1379 [7]

The volume of a right square pyramid is $V= \frac{1}{3} A_{\text{ basis } }\cdot h$ , where $A_{\text{ basis } }$ is basis area.

If the lengths of the sides of the base remain fixed and height
is multiplied by a factor 10, than new height is $H=10h$ and the volume is

$V^{\ast}=A_{\text{ basis } }\cdot H=\frac{1}{3} A_{\text{ basis } }\cdot 10h=\frac{10}{3} A_{\text{ basis } }\cdot h$

A scale drawing of a building has the scale 0.5in : 6ft. A wall is 30 ft long. How long will the wall be on the drawing?

g100num [7]

The scale 0.5 in : 6 ft, means that

any distance of 0.5 in on paper, represents 6 ft in reality

for example:

0.5*2= 1(in) represents 6*2=12 (ft)

0.5*4= 2(in) represents 6*4=24 (ft)

0.5*10=5(in) represents 6*10=60 (ft) and so on...

Let the wall be x (in) in the drawing:

0.5 (in) represents 6 (ft),
x (in) represents 30 (ft)
----------------------------------------

thus x = (0.5*30)/6 = 15/6= 2.5 (in)

Answer: 2.5 in
