What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)?

X=4
Step 1: Simplify both sides of the equation.
1.5(x+4)-3=4.5(x-2)
(1.5)(x)+(1.5)(4)+ -3 =(4.5)(x)+(4.5)(-2)
(1.5x) + ( 6+-3) =4.5x - 9
(Combine like terms)
1.5x+3=4.5x-9

Step 2: Subtract 4.5x from both sides.
1.5x +3 -4.5x =4.5x=-9-4.5x-3x+3=-9

Step 3: Subtract 3 from both sides.
-3x+3-3=-9-3
-3x=12

Step 4: Divide both by -3
-3x/-3=-12/-3
X=4

Point C has the coordinates (-1,4) and point D has the coordinates (2,0). What is the distance between points C and D? Is ____ u
beks73 [17]

Answer: 5 units

Step-by-step explanation:

Distance = \sqrt{(x_{2 }- x_{1 })^2 + (y_{2 }- y_{1 })^2\\

= \sqrt{(2_ }- (-1)_{ })^2 + (0_{ }- 4_{ })^2

= \sqrt{(2_{ }+ 1_{ })^2 + (-4)^2_

= \sqrt{3^2+(-4)^2}

= \sqrt{9+16}

= \sqrt{25}

= 5 units

LenKa [72]

Answer:

36 minutes

Step-by-step explanation:

It takes 45 mins to deliver paper on her route.

Let X be the amount of time it takes the brother to complete the route.

The brother works at the rate of 1/x route per min

The girl works at the at the rate of 1/45 route per min

Girl and brother working together works at rate of 1/20 route per min

1/x + 1/45 = 1/20

Multiply through by 180x

180 + 4x = 9x

4x - 9x = -180

-5x = -180

x = -180 / -5

x = 36 mins.

It takes the brother 36 minutes to complete route alone.
