Answer:
580 seedlings altogether.
Step-by-step explanation:
Given that,
Ali plants 40% of the total number of seedlings, Ben plants 45% of the total number of seedlings, and Cliff plants the rest of the seedlings. Cliff plants 87 seedlings.
The percentage of the seedling planted by Cliff = 100% - 45% - 40% = 15%
<em>Let x = the total number of seedlings</em>
<em />
Hence, three boys plant 580 seedlings altogether.
Answer:
x=4
Step-by-step explanation:
3(3x+2)=7(x+2) Cross product
9x+6=7x+14 Solve for x
9x-7x=14-6
2x=8
x=8/2
x=4
Answer:
volume = 450 mm³
Step-by-step explanation:

Answer:
y = -2x
Step-by-step explanation:
A "direct variation" relationship has the form y = kx, where k is the "constant of proportionality.
Note that this graph goes thru the origin (which it must, to represent direct variation), and that it has a steep negative slope. That narrows down the answer choice to the first one: y = -2x.
