4x+7=2x+11
4x-2x = 2x
2x+7=11
11-7 = 4
2x = 4
2/2 4/2
x=2
C. <2 is the correct answer
Y = 15x + 12
From the start, she paid $12, and each day, she paid an extra $15.
The answer is B.
I think it's how the shading goes all the way to x=5.
V=πr²h+(2/3)πr³
<span>πr²h+(2/3)πr³=V
</span>πr²h=V-<span>(2/3)πr³
</span>h=(V-(2/3)πr³) / (<span>πr²)
h=V/</span><span>πr² - 2/3r
Answer i: </span>h=V/<span>πr² - (2/3)r
Data:
V=245
r=7
h=(245 / 49</span>π) - (14/3)
h=(5/π) - (14/3)
h=(15-14π)/3π
h=-3.075
Answer ii: h=-3.075
