Answer:

Isolate x by multiplying by 4 to each side of the inequality

Step-by-step explanation:

You have x in a fraction, and you want to have x by itself on one side of the equation. In this case, you need to multiply by 4 to each side of the inequality to cancel the 4 on the left hand side of the inequality and leave x on its own. The final inequality is $x>52$ .

If I helped, a brainliest answer would be greatly appreciated!

Y+ 1/2 =-3/4 How would you do this one

UkoKoshka [18]

$y+\frac{1}{2}=-\frac{3}{4}\ \ \ |Add\ \frac{1}{2}\ to\ each\ side\\\\
y=-\frac{3}{4}-\frac{1}{2} \ \ \ |Make\ a common\ denominator\\\\
y=-\frac{3}{4}-\frac{2}{4}\\\\
y=-\frac{5}{4}=-1\frac{1}{4}\\\\

Each DVD storage case is about 1/5 inch thick. What will be the height in simplest form of 12 cases sold together?

Dominik [7]

Answer:

Height of the 12 cases will be = $2\frac{2}{5}$ inches.

Step-by-step explanation:

Thickness of each DVD storage case = $\frac{1}{5}$ inches

Let number of DVD storage cases sold = x

Therefore, the height of cases sold will be represented by the expression $\frac{x}{5}$

If the number of cases sold x = 12

So the height of the cases sold will be = $\frac{12}{5}$ inches

= $2\frac{2}{5}$ inches

Therefore, the answer is $2\frac{2}{5}$ inches.

Two similar triangles have have areas of 75 m2 and 12 m2. find the ratio of the perimeters

soldi70 [24.7K]

we know that having similar triangles so the ratio of sides,area and volume are same.

$s/s=s^2/s^2$

we know that $s^2$ will be the area of triangle.

$s^2/s^2=75/12$

so $s/s=\sqrt{75/12}$

so the ratio of the perimeter of two triangles will be

$(s+s+s)/(s+s+s)=(\sqrt{75} +\sqrt{75} +\sqrt{75} )/(\sqrt{12}+\sqrt{12} +\sqrt{12} )$

ratio of the perimeter= $\sqrt{225} /\sqrt{36}$

This is for Algebra 2 and I need help ASAP! 22pts if you show work and explanation

elixir [45]

Answer:

Part 41) The solutions are 3 and 1

Part 42) The solution is 2 only

Step-by-step explanation:

Part 41) we have

$\left|5x-9\right|=x+3$

step 1

Find the first solution (case positive)

$+(5x-9)=x+3$

$5x-x=3+9$

$4x=12$

$x=3$

step 2

Find the second solution (case negative)

$-(5x-9)=x+3$

$-5x+9=x+3$

$5x+x=9-3$

$6x=6$

$x=1$

therefore

The negative case was resolved incorrectly

The solutions are 3 and 1

Part 42) we have

$\left|n-7\right|=3n-1$

step 1

Find the first solution (case positive)

$+(n-7)=3n-1$

$3n-n=-7+1$

$2n=-6$

$n=-3$

<em>Verify</em>

For n=-3

substitute

$\left|-3-7\right|=3(-3)-1$

$\left|-10\right|=-9-1$

$10=-10$ ------> is not true

therefore

$n=-3$ -------> is not a solution

step 2

Find the second solution (case negative)

$-(n-7)=3n-1$

$-n+7=3n-1$

$3n+n=7+1$

$4n=8$

$n=2$

therefore

The solution is 2
