Y intercept (x = 0)
4(0)+3y=12
3y = 12
y = 12/3
y = 4
X intercept (y = 0)
4x+3(0)=12
4x = 12
x = 12/4
x = 3
R/ The intercept with x is (3,0) and with y (0,4)
7) x= men
x+6= women
x + (x+6)= 30
2x + 6= 30
2x= 24
x= 12
x+6= 18
8) x= first integer
x+1= second integer
x+2= third integer
x + (x+1) + (x+2)= 153
3x + 3= 153
3x= 150
x= 50
Second integer
= x+1
= x+50
= 51
9) x= first integer
x+2= second integer
x+4= third integer
x + (x+2) + (x+4)= 54
3x + 6= 54
3x= 48
x= 16
x + (x+2)= 34
16 + 16 + 2= 34
34=34
10) rate= 356 km/hr
distance= 1424 km
Distance= rate * time
D= rt
1424= 356 * t
divide both sides by 356
4 hrs= t

Multiply then add and then subtract
Answer:
the balls are larger, or don't pack as tightly
Step-by-step explanation:
The volume by either measure will depend on a couple of factors:
- the volume of the unit used (ball or cube)
- the way the units can be packed
In a rectangular space, such as a box, it may be easier to pack cubes than balls. So, more cubes of the same volume would fit simply because they can be packed closer together.
We aren't told the volume of either the cube or the ball, and we're not told the extent to which the packing is optimized.
Fewer balls may fit because their packing is not as well optimized as that of the cubes, or because each has a larger volume than the cube being used.
