1800 ft² = 3 pounds

[divide by 3 through]
1800 ÷ 3 = 3 ÷ 3
600ft² = 1 pound

[8400 ÷ 600 = 14; so multiply by 14 through]
600 x 14 = 1 x 14
8400ft² = 14 pounds

we need 14 pounds to cover 8400 square feet.

[Find number of 4 pounds bags needed]
14 ÷ 4 = 3.5
So we need to use 4 bags of 14 pounds of lawn seeds.

Value of t? 1.4t — 0.4 (t — 3.1) = 5.8
IceJOKER [234]

Hi!

<h3>Use the distribution property</h3>

1.4t — 0.4 * t - 0.4 * —3.1 = 5.8

1.4t — 0.4t - 1.24 = 5.8

<h3>Simplify</h3>

1t - 1.24 = 5.8

<h3>Add 1.24 to both sides</h3>

1t - 1.24 + 1.24 = 5.8 + 1.24

1t = 7.04

<u>t = 7.04</u>

<h2>The answer is t = 7.04</h2>

Hope this helps! :)

the formula for an exponential function is:

y=a*b^x

-50x=-10

x=-10/-50

x=1/5

x=2/10

Help I'm stuck on this problem
ollegr [7]
Easy! 

All you have to do is make a number lower or higher according to the symbols and make it unique.

For example, on letter B, it says ____ - ____ = <1

So what you want to do is make it 0 - 0 = <1
