Painting is 2 in by 1.5 in. Scale is 1 in:40 cm. What are the dimensions of the original painting?

Answers

Answer:

80 cm by 60 cm

Step-by-step explanation:

To solve this we know that the scale is 1 In: 40 Cm since our painting is already in inches all we have to do is multiply the inches by 40, so 2 inches * 40 is 80 and 1.5 * 40 is 60 and now all we do is turn the units into centimeters and we are done!

Show all your work x+14=4

Answers

to solve, you need to get the variable by itself. Do this by subtracting 14 from both sides. 

X +(14 - 14) = 4 - 14

Solve this now, so it is

X+ (0) = -10

X= -10

The answer is -10
x + 14 = 4
 take 14 to the other side to isolate x

x + 14 - (14) = 4 - (14)

x = -10
