Each ruler would cost about 9 cents
To find the scale factor of the dilation, divide the new point's x and y values by the original point's x and y values:
The scale factor of the dilation is
0.75.
Answer: $4
The cost of an 8x10 piece is $2, and 16x20 is just 2 times that amount, multiply the cost.
Answer:
w = -7/6 u
Step-by-step explanation:
The independent variable is in the equation, we solve for the dependent variable
So we solve for w
4u + 8w = -3u + 2w
Subtract 2w from each side
4u + 8w-2w = -3u + 2w-2w
4u+6w = -3u
Subtract 4u from each side
6w = -3u-4u
6w = -7u
Divide by 6
6w/6 = -7u/6
w = -7/6 u
