Answer:
-3x> or equal to -30; answer number 1
Step-by-step explanation:
-3x> or equal to as the dot is filled in. and it's heading towards the negative which mean it's equal to or less than 10.
Also -3x/-30 = -x>-30/-1 when you divide by a negative flip the sign.
so x< or equal to 10.
or -3x> or equal to -30
Answer:
63
Step-by-step explanation:
Assume, instead of > there was a =
In that case, x ÷ 7 = 3, then x would be 21. But we want a value that will be exceed this 21. So the only option you have is 63.
So some quick tips for inequalities:
**What you do to one side you HAVE TO do it to the other 2**
**If you ever divide a negative number past the inequality signs, the signs FLIP!!**
(e.g. 2>-5x>25)
-2/5 <x < -5
I hope that this has helped!
F(5)=x*10=50
um..
5x+5x+(2x+4)+(2x+4)=50
