What number gives a result of -4 when 9 is subtracted from the quotient of the number and 5?
Vera_Pavlovna [14]
Answer:

25

Step by step:

1. prepare the equation

-4 = x/5 - 9

2. add 9 to both sides

-4 = x/5 - 9
+9 +9
5 = x/5

3. multiply both sides by 5

5 = x/5
(5) (5)
25 = x

4. x=25

−5.5x + 0.46 = −3.94
aliina [53]

Answer:

x= 0.78 (rounded to the hundredth)

Step-by-step explanation:

-5.5x + 0.46 = -3.94

You need to isolate x so the easiest thing to do is subtract 0.46 and move it to the other side of the equal sign.

-5.5x= -3.84 - 0.46

-5.5x = -4.3

divide -5.5 to get x alone

x= -4.3/-5.5

x= 0.78

I'm may not be that good at math, but I'm going to try my best to help you, because I know how it feels to be in this situation! 

The first one : 
You might be right on D. But I'm thinking B also. The question asks "Which could be a cross section of a rectangular pyramid that has been intersected by a plane perpendicular".  But a triangle is basically a flat pyramid. 

(I'm typing really fast to help!!!!) 

Second one: Its B!! Look at it really closely! You'll get it!!!

(Going really fast now!!!!) 

Third one: Between B or D!!! But I think you're right on your choice!!!!

(FASTER FASTER!!!) 

FINALLY: Copy and paste your answers into google. People have asked the same question! 

I hope I helped. I don't want to make you fail, as I am in the SAME similar situation as you! I really REALLY REALLY HOPE YOU PASS!!!
