Could someone help me pls with this question it is math !

Answer:

B) 275n + 1000 = 2700

Step-by-step explanation:

n is just a placer holder for how many days the Carter family can vacate.

That being said, the question says that they will spend 275 per day, which is per n. You want to multiply 275 by n.

Then the question says it plans to spend $1000 on meals (that's a lot). Instead of substracting, you are going to add for this equation. You want the equation to match; you want both sides to equal 2700 so you can determine how many days you can spend there.

Given that f(x)= 9x^2-180, find x
hoa [83]
9x^{2}  - 180 = 0

9x^{2}  = 180

Divide both sides by 9

 x^{2} = 20

Square root both sides, and you get

x =  \sqrt{20} --\ \textgreater \  simplified: 2 \sqrt{5}

How many grades of fuel oil are normally considered as heating oils?
harina [27]
<span>In the U.S., three grades of fuel oil used for heating are generally recognized. The grades are No. 1, No. 2, and No. 4. No. 1 heating oil is more highly refined than No. 2, and is less viscous. For this reason, it is more suitable for outdoor storage in very cold climates.</span>
