Answer:
If x varies directly as y, then x=ky. y=5 and x=2.5 are substituted into x=ky to find k.
2.5=5k
k=2.5/5
k=5.
K =5 is substituted in x=ky to find y where x is 10.
x=5y
10=5y
y=10/2
y=2
Answer:
30 cubes
Step-by-step explanation:
To find the number of small cubes in the larger cuboid, you can multiply the number of cubes that make up the length, width and height together.
There are 5 cubes along the bottom, 2 along the side and 3 going up. The volume would be 5 × 2 × 3 which is 30 cubes.
Hope this helps!
10% of all the cars is 20 limos.
20 * 10 = 200 cars total.
limos + vans + sedans = total cars
200 cars total - 20 limos - 60 vans = x sedans
x = 120 sedans
Answer:
Step-by-step explanation:
120 + 120 + X + X = 360
240 + 2X = 360
2X = 120
X = 60
