1.5(x+4)-3=4.5(x-2)

First, distribute 1.5 into x and 4, and 4.5 into x and -2, to get rid of the parentheses. Everything that we do to solve this equation is to isolate x to solve for its value.

1.5x+6-3=4.5x-9

Combine like terms on both sides (6-3).

1.5x+3=4.5x-9

Subtract 1.5x from both sides.

3=3x-9

Add 9 to both sides.

12=3x

Divide both sides by 3.

4=x

The answer is 4.

I hope this helps :)

square GYTD has vertices G(-4,3), Y (0,3), T (0,-1) and D (-4, -1) square GYTD is translated 2 units left and 2 units up to prod

WARRIOR [948]

ANSWER:
G’(-6,5) Y’(-2,5) T’(-2,1) D’(-6,1)

WORK OUTS:
G’=(-4-2,3+2)=(-6,5)
Y’=(0-2,3+5)=(-2,5)
T’=(0-2,-1+2)=(-2,1)
D’=(-4-2,-1+2)=(-6,1)

EXPLANATION:
Because the translation is 2 units to the left, which makes it -2(going to the right is positive and the left is negative). Then you will subtract 2 from each x value because translating right and left effects the x value of the coordinates.
You were also given that the translation is 2 units upwards ( going upwards is positive and downwards is negative) therefore the 2 will stay positive. Then you will add 2 to each y value because translating up and down effects the y value of the coordinates.

The lung capacity of the blue whale is 5100L. Convert this volume into gallons. Express your answer to two significant figures a

Vedmedyk [2.9K]

By definition, we have that the conversion of a US gallon to liters is given by:
1 liter = 3.78541 gallons
Therefore, we can apply the following rule of three:
1 liter ---------------------> 3.78541 gallons
5100 liters --------------> x
Clearing x we have:
$x = (5100) * (3.78541)

x = 19305.591$
two significant figures:
$x = 19000
$
Answer:
The lung capacity of the blue whale is:
$x = 19000 gallons$
