Answer: -2

Step-by-step explanation:

The information in the question can be used to form an equation which goes thus:

2nd term = a + d = 4 ...... i

5th term = a + 4d = 22 ....... ii

From equation i

a = 4 - d ........ iii

Put equation iii into ii

a + 4d = 22

(4 - d) + 4d = 22

4 - d + 4d = 22

4 + 3d = 22

3d = 22 - 4

3d = 18

d = 18/3

d = 6

Commons difference is 6

Since a + d = 4

a + 6 = 4

a = 4 - 6

a = -2

The first term is -2

Choose the equation that models the following statement: The current, I amps, produced by a battery is inversely proportional to
Anika [276]
By definition we have to:
 V = I * R
 Where,
 V: Voltage.
 I: Current.
 R: Resistance.
 The current, I amps, produced by a battery is inversely proportional to the resistance, R ohms. Clearing I have:
 I = V / R
 rewriting:
 I = V * (1 / R)
 answer:
 The equation that models the statement is:
 I = V * (1 / R)

Tito receives a weekly salary of ​$450 at an appliance store. He also receives a 4 percent commission on the total dollar amount
Kay [80]
<h2>Hello!</h2>

The answer is:

Tito needs a total of $6500 in sales if he want to receive $710 a week.

The equation is:

TotalAmount=450+Sales*0.04

<h2>Why?</h2>

From the statement we know that his salary is $450 plus a 4% commission on the total amount of all sales he makes.

So, we can write the following equation to determine the total sales in a week if he wants to make a total of $710.

Remember, if we are working with percents, we need to change it to real numbers in order to perform the calculations, we can do it by dividing the percent value into 100.

We have:

TotalAmount=450+Sales*0.04

Now, if he wants to make a total of $710, we have:

750=450+Sales*0.04

750-450=Sales*0.04

Sales=\frac{710-450}{0.04}=6500

We have that Tito needs a total of $6500 in sales if he want to receive $710 a week.

Have a nice day!
