Answer:
53 pushes
Step-by-step explanation:
Total Volume of soap = 474 mL
Volume per push = 8mL
Mimimum volume required = 50mL
The equation which represents the number of push, x that can be made :
Total volume = minimum volume + (volume per push * number of pushes)
Total volume = 50 + (8 * x)
474 ≤ 50 + 8x
474 - 50 ≤ 8x
424 ≤ 8x
53 ≤ x
The number of pushes that can be made = 53
Answer:
(D) (a + 4)/2
Step-by-step explanation:
To solve, you need to subtract the first equation from the second.
9p = 3a + 1
<u>- 7p = 2a - 3</u>
2p = 1a + 4
Now, you need to rearrange the equation so that is equal to p.
2p = a + 4
(2p)/2 = (a + 4)/2
p = (a + 4)/2
This gives you answer choice D.
Answer:
b = 36
Step-by-step explanation:
27 divided by 6 = 4.5
45 divided by 10 = 4.5
- so, each point was multiplied by 4.5
8 times 4.5 = 36
Let's resolve the powers of 10 to make them comparable
47000
45000
5000
280000
125000
Now you can see the largest is 280000 and the smallest is 5000
Their difference is 280000 - 5000 = 275000
