Answer:
x = 1000
Step-by-step explanation:
5,350 ÷ x = 5.35
To find this you should divide 5,350 by 5.35.
5,350 ÷ 5.35 = 1000
x = 1000
Answer:
n= -3
Step-by-step explanation:
First, your're going to subtract from both sides
6n + 21 - 2 1= -3 - 2n - 21
Then simplify
6n = -2n - 24
Then add 2n on both sides
6n + 2n = -2n -24 + 2n
Simplify again
8n = -24
Then divide both sides by 8
8n/8 = -24/8
Then simplify and this is your answer
n= -3
Answer:
-3 1/8.
Step-by-step explanation:
−7/8 − 2 1/4
= -7/8 + -9/4
= -7/8 - 18/8
= -25/8
= -3 1/8.
