Answer:
x = 6, y = -2
Step-by-step explanation:
24/4 = 6
x = 6
= (5x6)+8y=14
= 8y = 14 -30
8y = -16
y = -16/8
y = -2
Check: 5x6+8x-2= 14
Answer:
c) -1
Step-by-step explanation:
-2-3-(-4)
=-5+4
=-1
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
This one is a bit trickier but I do believe the answer is B. About 30 ft2 to 40ft2. Let me know if you need any more help!!!
