Answer:

Step-by-step explanation:
Given





Required
Determine the length of TU (i.e. x)
Because both shapes are similar, then the following equivalent ratios exist:

Substitute values for NO, OP, TU and UV

Represent as fraction

Multiply both sides by 6





Hence:

Answer:
w = 6
Step-by-step explanation:
5w-26 = - 4 (w - 7) multiply -4 through
5w - 26 = - 4w + 28 add 4w to each side to cancel it out on the right
5w + 4w - 26 = 28
9w - 26 = 28 Now add 26 to each side
9w - 26 + 26 = 28 + 26
9w = 54 Now divide each side by 9
(9w)/9 = 54/9
w = 6
9,471 divided by 8 is 1183.875. The image I've provided pretty much shows you the place values. The rest is self-explanatory.
Answer:

Step by step explanation:
So I done 6x5 as if it was 600x5, then I would do 60x8
600x5=3000
60x8=480
3000+
480=
