Answer: 17.75 pounds
Step-by-step explanation:
After putting soil in the first flower bed, Layla's bag was ⅝ full. The pound of soil will be: = 5/8 × 10 = 6.25 pounds
Eliana's bag was ⅖ full. The pound of soil will be: = 2/5 × 10 = 4 pounds
Nature's bag was ¾ full. The pound of soil will be: = 3/4 × 10 = 30/4 = 7.5 pounds
The number of pounds of soil that they put in the first flower bed altogether will be:
= 6.25 + 4 + 7.5
= 17.75 pounds
Answer:
<h2>x = 10</h2>
Step-by-step explanation:
If the triangles are similar, then the corresponding sides are in proportion:
![\dfrac{20}{20+8}=\dfrac{3x}{4x+2}](https://tex.z-dn.net/?f=%5Cdfrac%7B20%7D%7B20%2B8%7D%3D%5Cdfrac%7B3x%7D%7B4x%2B2%7D)
![\dfrac{20}{28}=\dfrac{3x}{4x+2}](https://tex.z-dn.net/?f=%5Cdfrac%7B20%7D%7B28%7D%3D%5Cdfrac%7B3x%7D%7B4x%2B2%7D)
![\dfrac{20:4}{28:4}=\dfrac{3x}{4x+2}](https://tex.z-dn.net/?f=%5Cdfrac%7B20%3A4%7D%7B28%3A4%7D%3D%5Cdfrac%7B3x%7D%7B4x%2B2%7D)
<em>cross multiply</em>
<em>use distributive property </em><em>a(b + c) = ab + ac</em>
![(5)(4x)+(5)(2)=21x](https://tex.z-dn.net/?f=%285%29%284x%29%2B%285%29%282%29%3D21x)
<em>subtract 20x from both sides</em>
![10=1x\to x=10](https://tex.z-dn.net/?f=10%3D1x%5Cto%20x%3D10)
