Meryl needs to cut down 10.5 trees for every 5 cabins she builds. how many trees would she need to build 7 cabins​
Sidana [21]

Answer:

<h2>14.7 Trees</h2>

Step-by-step explanation:

We solve this using a proportion.

\frac{10.5}{5} = \frac{x}{7}

10.5 x 7 = 73.5

5x = 73.5

x = 14.7

Now let's check the proportion.

\frac{10.5}{5} = \frac{14.7}{7}

10.5 x 7 = 73.5

14.7 x 5 = 73.5

73.5 = 73.5 ✅

Wilma works at a bird sanctuary and stores birdseed in plastic containers. She has 2 small containers that hold 8 pounds of bird
Amanda [17]

Answer:

 60 lbs left over

Step-by-step explanation:  Since the small containers hold 8 lbs each you multiply 8 by 2 since there are 2 containers. Same for the large, multiply 9 by 12 because each container holds 12 lbs and there is 9 containers. Then, you subtract 4 from that total because she already used 4 lbs.

x=(2*8)+(9*12)-4 Multiply

x=16+108-4 Simplify

x=120

So, before she fills the bird feeders she has 120 lbs of bird seed. There are 30 bird feeders and since they hold 2 lbs each you multiply 30 and 2. Then you subtract that from the 120 lbs because she is filling the bird feeders with that seed.

120- (30*2)

120-60= 60 lbs left over
