13: multiply the amount by the tax rate (to make a percent a decimal move the decimal point 2 places to the left) and add the original amount and the taxed amount together. For 12 do above but then multiply the total by the tip rate and add together (basically the same as the tax again) :) I hope this helps

Rewrite the expression in the form 7^n 7^2 x 7^6

s2008m [1.1K]

Answer:

The expression in the form $7^n$

$7^2\times \:\:7^6=7^n$

Step-by-step explanation:

$7^2\:\times \:7^6$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^b\times \:a^c=a^{b+c}$

$7^2\times \:7^6=7^{2+6}$

So the expression becomes

$7^2\:\times \:7^6=7^{2+6}$

$=7^{2+6}$

Add the numbers: 2+6=8

$=7^8$

Therefore, the expression in the form $7^n$

$7^2\times \:\:7^6=7^8$

-2(x-4)=-16 SOLVE FOR X!!

Andrej [43]

Answer:

x = 12

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

-2(x - 4) = -16

Step 2: Solve for x

Distribute -2: -2x + 8 = -16
Isolate x term: -2x = -24
Isolate x: x = 12

Step 3: Check

Plug in x to verify it's a solution.

Substitute: -2(12 - 4) = -16
Subtract: -2(8) = -16
Multiply: -16 = -16

Here we see that -16 does indeed equal -16.

∴ x = 12 is a solution of the equation.

Answer:

28 inches

Step-by-step explanation:

To find the value of x you put them into an equation of: (x+6) = (3x+2), this would let you find that x=2, since 2+6 = 6+2. Once you've plugged that in all you need to do is add together all the sides, and since side A and side B are both 8 you do 12+16 to get the perimeter of 28 inches.
