Answer:
x = 20.
Step-by-step explanation:
This is a right triangle, so by Pythagoras:
29^2 = x^2 + 21^2
x^2 = 29^2 - 21^2
x^2 = 400
x = √400
x = 20.

Answer:
y = 4x - 17
Step-by-step explanation:
we can use the equation y = mx + b
where m is the slope.
now we want to find the value of b.
so
7 = 24 + b
b= -17
so the answer is
y = 4x -17
What Question are you stuck on??
Answer:
19 28/33
Step-by-step explanation:
lets work out the whole number parts first:
= 19 + 17 - 16 = 20.
4/12 + 2/11 - 6/9
= 1/3 + 2/11 - 6/9
Find the LCM of the denominators:
3 = 3
11 = 11
9 = 3*3
- so the LCM is 3*3*11 = 99.
So we have:
33/99 + 18/99 - 66/99
= 51/99 - 66/99
= -15/99
= -5/33
So the answer is 20 - 5/33
= 19 28/33
You just had to subtract 5/33 from 20.
