Hello!

To solve this equation, you need to follow SADMEP. SADMEP is subtract, addition, division, multiplication, exponents, and parentheses (if you notice it is PEMDAS backwards) when solving algebraic equations. The goal is to get the variable by itself.

n - 3/5 = 2/5 (add 3/5 to both sides - the denominator of both fractions are equal)

n = 1

Therefore, the value of the variable n is equal to 1.

alexandr1967 [171]

To solve for the total amount that Alice paid for the 3 yards cloth, multiply the cost per yard with the additional 5% to number of yards. 5% of 93 is 4.65. The total cost per yard of cloth is 97.65. Multiplying the total cost with 3 will give 292.95. Thus, Alice paid 292.95 dollars in total.

iVinArrow [24]

Answer:

Her hourly rate is $14.

Step-by-step explanation:

Given:

Penelope goes to work after school for 4.5 hours on Mondays, Tuesdays, and Fridays.

She works 8 hours each on Wednesdays or Thursdays.

Now, to find her hourly rate.

So, total hours Penelope work on Mondays, Tuesdays, and Fridays:

$4.5+4.5+4.5=13.5\ hours.$

And, total hours she work on Wednesdays and Thursdays:

$8+8=16\ hours.$

Now, the total hours each week she work:

$13.5+16=29.5\ hours.$

Total money she makes each week = $413.

Now, to get the hourly rate we divide the total hours each week she work by total money she makes each week:

$413\div 29.5$

$=\$14.$

Therefore, her hourly rate is $14.

The correct answer is: [B]: " 3 " .
_______________________________________________
Note:
_______________________________________________
The question asks:
_______________________________________________
If (5⁴)ᵐ = 5¹² ; then what is "m" ?

Note the following property of exponents:
________________________________________________
(xᵃ)ᵇ = x⁽ᵃ*ᵇ⁾ ; a≠0 ; b ≠ 0 ;

Then, (5⁴)³ = 5⁽⁴ * ³⁾ = 5¹² .

So, "12 ÷ 4 = 3" .
