Answer:
The second one
Step-by-step explanation:
First you subtract -4 from -37 & you get -33 ( not positive ) and so then that leaves you with 0.5n-33=2n (because there’s obvi no 4 anymore since you canceled it out) and then you subtract 0.5n from 2n and get 1.5n and so then you have the -33=1.5n and then you just divide 1.5 by -33 to get ur anwser
First, we'll want to write out the equation
then reduce what we can
so this means n can equal any whole number between 9 4/9 & 12, which gives us the options of {10,11}
Answer: 7 cm
Step-by-step explanation:
We know that, Triangle's area= 0.5 × Base × Height
So,
28 = 0.5 × 8 × Height
⇒Height= {28/(0.5 ×8)} = 7 cm
Answer:-5
Step-by-step explanation:
You need to distribute on both sides so u get
9c-15=20-2c
Move variable to left side and change the sign
-9c+2c-15=20
Move constant to right side and change the sign
-9c+2c=20+15
Connect like terms
-7c=35
Divide
C=-5
