Step-by-step explanation:
3x + 1
=3x + 1
this is because a variable X is attached to the 3 so it makes the 3x and the 1 unlike
therefore you can not add them.
Answer:
Hi, I love these types of questions. So, ima teach you how to find the answer. If your only looking for an answer, skip to the bottom. So, what your trying to find is the solution to 3/10 divided by 6/11. So, remember, copy, dot, flip.
Copy- Copy the equation- 3/10 6/11
Dot- Change the division sign to multiplication- 3/10 X 6/11
Flip- so, this is where it gets a bit tricky. You wanna flip the numerator and denominator on the second fraction- 3/10 X 11/6
now multiply across-
33/60
simplify
11/20
Your answer is 11/20
Answer:
a. 10√2
Step-by-step explanation:
hey, just use Pythagoras theorem
h²=p²+b²=10²+10²=100+100=200
h²=200, h= √200 =√(100×2)=√100×√2=10√2
Answer:
RS = 20
ST = 40
Step-by-step explanation:
R____S____T
RS + ST = RT
3x - 16 + 4x - 8 = 60
3x + 4x - 16 - 8 = 60
7x - 24 = 60
+24 +24
--------------------------------
7x = 84
/7 /7
---------------------------------
x = 12
Let's use what we got for x to find the length of ST and RS
ST = 4x - 8
= 4(12) - 8
= 48 - 8
ST = 40
RS = 3x - 16
= 3(12) - 16
= 36 - 16
RS = 20
so, RS = 20, ST = 40, and RT = 60
