Step-by-step explanation:
Answer:
120
Step-by-step explanation:
Given data
36 members are equivalent to 30%
Let the total number of students be x
Hence
30% of x= 36
30/100*x= 36
0.3x= 36
divide both sides by 0.3
x= 36/0.3
x= 120 students
Hence the total number of students is 120
It's the first one (7+4i)+(7-4i)=14
Answer:
10x²+11-2x
Step-by-step explanation:
I hope you mean 7x²+8+5, not 7x²+8x+5.
We need to combine like terms. Anything with squared should be added together, et cetera.
(7x²+8+5)+(3x²-2x-2)
You can take out the parenthesis, because they don't matter in addition.
7x²+8+5+3x²-2x-2
Add the terms, step by step. Each bold pair needs to be added together.
7x²+8+5+3x²-2x-2
10x²+8+5-2x-2
10x²+11-2x
Now there's no more we can add together.
X/(-9) = 16
x/(-9) x (-9) = 16(-9)
x = 16(-9)
x = - 144
hope this helps
