-3(x-1)+8(x-3)=6x+7-5x
-3x+3+8x-24=6x+7-5x
-3x+8x-6x+5x=7-3+24
4x=28
4x/4=28/4

Answer:

x = 7

Step-by-step explanation:

-3(x - 1) + 8(x - 3) = 6x + 7 - 5x

<em>multiply in "-3" and "8"</em>

-3x + 3 + 8x - 24 = 6x + 7 - 5x

<em>move </em><em>the </em><em>unknowns </em><em>to </em><em>the </em><em>left </em><em>and </em><em>constants </em><em>to </em><em>the </em><em>right </em>

-3x + 8x - 6x + 5x = 7 - 3 + 24

4x = 28

<em>divide </em><em>both </em><em>sides </em><em>by </em><em>4</em>

x = 7

Joyce has a cone shaped planter hanging on her back porch. If the planter has a radius 6.8 inches and a height of 12.2 inches, w
andriy [413]

Answer:

The total amount of soils that planter will hold to it is 590.45  inches³

Step-by-step explanation:

Given as :

The radius of the cone shape planter = r = 6.8 inches

The height of the cone shape planter = h = 12.2 inches

Let The total amount of soils that will hold to it = x cubic inches

Now, According to question

The total amount of soils that planter will hold to it = The volume of the cone

∵ The volume of cone = v = \dfrac{1}{3} \pi r² h

where r is the radius

And h is the height

So, The total amount of soils that planter will hold to it =  \dfrac{1}{3} \pi r² h

or, x = \dfrac{1}{3} × \pi × r² × h

or, x =  \dfrac{1}{3} × 3.14 × (6.8)² inches × 12.2 inches

or, x =  \dfrac{1}{3} × 3.14 × 564.128 inches³

or, x =  \dfrac{1}{3} × 1771.361  inches³

or, x = \dfrac{1771.361}{3}  inches³

∴  x = 590.45  inches³

So, The total amount of soils that planter will hold to it = x = 590.45  inches³

Hence, The total amount of soils that planter will hold to it is 590.45  inches³   . Answer
