Pythagorean Theorem is really easy once you get the hang of it.
So you have right angle, angles a b and c. Angle a is at the bottom. Angle b is part of the right angle. And c is the longest part. A squared + b squared = c. So c has to always be the biggest number obviously. So if a is 4 and b is 7 what is c? 4 times 4 is 16 and 7 times 7 is 49. 16+49= 65. And then the square root of 65 is 8.06. The tenth is 0. 6 is greater then 5 so you round up so 0 will become a 1. So it'll be 8.1, also if a was 3 and b was 4 c would be 5. It'll always work like 30,40 and 50.

Answer:
£16:£144
Step-by-step explanation:
1+9=10
160/10=16
1×16=16
9×16=£144
Answer:
9
Step-by-step explanation:
Just divide the amount moved by the number of spaces. If you spun the same number 10 times, and went back 90 spaces, your number would be 90/10
5y = -3x + 7
y = -3/5x + 7/5
Parallel = same slope
y = -3/5x + b
3 = -3/5 + b, b = 18/5
Standard form: Ax + By = C
y = -3/5x + 18/5
-3/5x - y = -18/5
Multiply by -5
Solution: 3x + 5y = 18
<h3>
6/11 = y/3</h3>
<em>Multiply both sides by 3.</em>
<h3>6/11 × 3 = y</h3>
<em>Express 6/11 × 3 as a single fraction.</em>
<h3>6 × 3/ 11 = y</h3>
<em>Multiply 6 and 3 to get 18.</em>
<h3>18/11 = y</h3>
<em>Swap the sides so that all the terms of the variables are on the left side.</em>
<h3>y = 18/11</h3>
