Solve for x. 5. 150 - (2x + 90) = 4x

1 answer:

8 0

X=10

First, remove the parentheses so it could turn into 150-2x-90=4x (the plus sign gets turned into a minus sign because of a certain rule.

Then do 150-90 which will result in 60-2x=4x.

Then subtract -4x on both sides. This will leave you with 60-6x=0.

Next, subtract 60 in both sides. This will leave you with -6x=-60.

Finally, divide by -6 on both sides. This will leave you with the answer x=10.

Which set of points includes all of the solutions for y = negative three halves times x plus two? line going through 0 comma 2 a

worty [1.4K]

Answer:

$(x,-\frac{3}{2} x+2)$

Step-by-step explanation:

For $y= \frac{-3}{2} x+2$ the set of points that include all solutions are $(x,y)$ such that $y= \frac{-3}{2} x+2$ ; then we have $(x,y)=(x,\frac{-3}{2} x+2)$ .

What is important to stress here is that $(x,-\frac{3}{2} x+2)$ represents all of the solutions, while other points that we are given represent one solution (for example, point (2,-1) is just one solution)

If a cylinder has a height of 21 cm and a volume of 11,144 cm^3.

nataly862011 [7]

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\qquad 
\begin{cases}
h=height\\
r=radius\\
----------\\
h=21\\
V=11,144
\end{cases}\implies 11,144=\pi \cdot r^2\cdot 21$

solve for "r"
