N is a variable in algebra. Variables are letters that represent unknown numbers. Variables can be any letter of the alphabet.

Here's how to use n in an algebraic equation:

5 + n = 12

To find what N represents, let it be the only thing on the left side of the variable:

5 -5 + n = 12 - 5

n = 7

Bianca’s Bike Shop made a profit of $54,000 last year. This year, the profits were 250% of last year’s. How much profit did Bian

Alexandra [31]

Since the percent increase is bigger than 100%, it definitely has to be more than 54,000.

so let's break this down:
250%= 100% + 100% + 50%

we know 100% is the whole price so if there are 2 100% we have to multiply the price by two!!!
54,000•2 = 108,000

now, 50% is half of the whole price, divide the price by two:
54,000÷2= 27,000

so add your results and you will get this!
108,000+27,000= 135,000

Whoever checks my work and tell what I did wrong and the right answer will

Answer:

See below

Step-by-step explanation:

I believe that you only had to do letters F, H, and J. In that case, let's go over each one!

F: For isolating $d_{1}$ , we need to get rid of the 1/2 first. Let's multiply each side by 2:

$2*m = 2*\frac{1}{2}(d_{1}+ d_{2}) \\2m = d_{1}+ d_{2}$

After this, we just subtract $d_{2}$ from each side to get $d_{1}=2m- d_{2}$ . Dark Blue is correct! Let's now plug in those numbers below:

$d_{1}=2(10)- 13 = 20-13=7$

G: Let's isolate the vw^2 on one side by subtracting y from each side:

$vw^{2} +y-y=x-y\\vw^{2}=x-y$

Let's now divide each side by v, then put each side under a square root to get our final answer:

$\frac{vw^2}{v} = \frac{x-y}{v}\\ w^2 = \frac{x-y}{v}\\\sqrt{w^2} = \sqrt{\frac{x-y}{v}} \\w=\sqrt{\frac{x-y}{v}}$

Orange is correct! Again, let's solve the problem underneath:

w= $w=\sqrt{\frac{38-(-7)}{5}} = \sqrt{\frac{38+7}{5}} = \sqrt{\frac{45}{5}}=\sqrt{9}=3$

H: This one has some stuff that we haven't worked with quite yet (like terms), but our approach is the same: isolate c on one side of the equation.

$2a-2a+3c=17a-2a+21\\3c = 15a+21\\\frac{3c}{3} = \frac{15a+21}{3}\\c = \frac{15a}{3}+ \frac{21}{3} \\c = 5a+7$

Purple is correct! Let's solve the problem:

$c = 5(\frac{16}{5})+7 = 16+7 = 23$
