10 pounds of soil are needed to

Mathematics
1 answer:
Wewaii [24]3 years ago
3 0

Answer:

40/3

Step-by-step explanation:

w = weight of soil needed

f = number of flower beds

a = constant value

w = a * f

<em>substitute</em>

10 = 6a

<em>simplify</em>

5/3 = a

w = (5/3)f

<em>plug in 8</em>

w = (5/3)(8)

<em>simplify</em>

w = 40/3

I'm really stuck on this math problem. I never learned this in school. Can someone please help me out? Thank you
romanna [79]
Hehe, these are fun to do. There are two ways to do this kind of problem. You can use the pythagorean theorem or we can use the distance formula.
Distance formula:
d= \sqrt{(x2-x1)^2+(y2-y1)^2}

Pythagorean Theorem:
a^2+b^2=c^2

Distance formula is better if you're finding distance between two coordinates. The Pythagorean Theorem only really works for independent values. If I had 2 sides of a triangle, and I needed to find the third, I'd use this equation to find it. In this case, we'll use the distance formula.

I'll work the first one out for you:
 x1   y1     x2  y2  
(3,   2) & (7,   4)

d= \sqrt{(7-3)^2+(4-2)^2}
                           v
d= \sqrt{(4)^2+(2)^2}
                           v
d= \sqrt{(16+4}
                           v
d= \sqrt{20}

There's your answer!

5x + 3 = 7x – 1. Find x
nasty-shy [4]

Answer:

x = 2

Step-by-step explanation:

5x + 3 = 7x - 1

Subtract 3 to both sides

5x = 7x - 4

Subtract 7x to both sides

-2x = -4

Divide by -2 to both sides.

x = 2
