Answer:
Yeah you are right
Step-by-step explanation:
Use formula p=m/v
P is density
M is mass
V volume
So you have the volume already now 8x5x4= 160 which is the volume
P= 1800/160 after you divide you get 11.25
The density is 11.25
Answer:
negative number
Step-by-step explanation:
-1
1/4 of -1 = -1/4
-1/4 is greater than -1
Answer:

Step-by-step explanation:
Since the ant travels at a constant speed, we can set up the following proportion:
, where
is the distance the ant can travel in 7 minutes.
Solving for
, we get:
.
X+2y = 9 ---------eq.1
x-y =6 ----------- eq.2
x = 9 -2y (from eq. 1)
Now substitute the value of x in the second eq.2
9-2y-y =6
-3y = -3
y =1
So,
x +2 (1)= 9
x= 7
