Answer:

Work done below!

Step-by-step explanation:

8x + c = k

Subtract c from both sides;

8x = -c + k

Divide both sides by 8;

$x = -\frac{1}{8}c +\frac{1}{8}k$

Answer:

A. x = k+c/8

Step-by-step explanation:

Might be the most accurate answer based on what I see above.

Since you are solving for x, you would first subtract c on both sides to get 8x = k - c. From there are on out, you would then divide 8 on both sides to get your final answer which is x = k+c/8.

Connie made deposits of $2,000 at the beginning of each year for four years. the rate she earned is 5% annually. what is the val

Dvinal [7]

To get the value of Connie's deposits we use the future value of annuity:
FV=P[((1+r)^n-1)/r]
where:
P=periodic deposits
r=rate
n=time
thus plugging our values in the formula we get:
FV=2000[((1+0.05)^4-1)/0.05]
FV=$8620.25

Answer: $8620.25

IrinaK [193]

He has to sell in a month $26616.67.

Given that a local salesman receives a base salary of $975 monthly and he also receives a commission of 6% on all sales over $1200.

A numerical assertion wherein two articulations are delivered equivalent to each other is known as an algebraic condition.

Let the Sales amount be s.

We have:

Sales over 1,200 is written as

s-1200

6% is also 0.06 as a decimal,

so according to question, we have

0.06(s - 1200) + 975=2500

Now, we will apply the distributive property a(b+c)=ab+ac, we get

0.06s-0.06×1200+975=2500

Further, we want to simplify the left-hand side, we get

0.06s-72+975=2500

0.06s+903=2500

Furthermore, we will subtract 903 from both sides, we get

0.06s+903-903=2500-903

0.06s=1597

Now, we will divide both sides with 0.06, we get

0.06s/0.06=1597/0.06

s=26616.67

Hence, he have to sell in a month if he needed to have a monthly income of $2500 is $26616.67.
