Gregory’s age is 5 years greater than of Amanda’s age. Gregory is 17 years old. If Amanda’s age is denoted by x, which equation

Mariana [72]

Let Amanda's age = x.
Gregory's age = x + 5.

Since Gregory is 17 years old.
17 = x + 5
x = 17 - 5
x = 12

Amanda is 12 years old.

Solve the inequality 2x - 5 \le -x +12. Give your answer as an interval.

ludmilkaskok [199]

Answer: $\begin{bmatrix}\mathrm{Solution:}\:&\:x\le \frac{17}{3}\:\\ \:\mathrm{Decimal:}&\:x\le \:5.66666\dots \\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:\frac{17}{3}]\end{bmatrix}$

Step-by-step explanation:

$2x-5\le \:-x+12$

$2x\le \:-x+17\\$

$2x+x\le \:-x+17+x$

$3x\le \:17$

$\frac{3x}{3}\le \frac{17}{3}$

$x\le \frac{17}{3}$

solve for the indicated variable. include all of your work in your answer. submit your solution. P=2L+2W; for L.

allochka39001 [22]

We have this equation:

$P=2L+2W$

So, we need to solve this equation for L. Then we sum -2W in each member of the equation, like this:

$P-2W=2L+2W-2W$
$P-2W=2L$

Then, dividing the equation by 2:

$\frac{P-2W}{2}=L$

Finally, let's order this equation:

$L=\frac{P-2W}{2}$
