Answer: A streaming service cost problem

Step-by-step explanation:

Hi, since the x is the variable, that will be the unknown value for our problem.

We can state a Cost equation,

y= ax +b

Where the total cost (y) of a streaming service in a month was $26.

The fixed fee per month of the streaming service (b) is $5, and the additional cost per movie rented (a) is $3.

How many movies (x) were rented in that month?

Feel free to ask for more if needed or if you did not understand something.

Answer: x= 7

Step-by-step explanation:

John has a total of 26 apples which is 3 times and 5 more than Peter's apple . Find the number of apple Peter has.

Let Peter's number of apples be x

This can be written as:

3x + 5 = 26

Collect like terms

3x = 26 - 5

3x = 21

x = 21/3

x = 7

Peter has 7 apples.

An abstract sculpture in the form of a triangle has a base 21 meters and a height of 12 meters. Find the are of the triangle.

charle [14.2K]

The area of a triangle could be determined using the following formula
$\boxed{a= \frac{1}{2} \times b \times h}$

plug in the numbers
$a = \frac{1}{2} \times 21 \times 12$
$a = \frac{1}{2} \times 252$
$a= \frac{252}{2}$
a = 126

The area of the triangle is 126 square meters

Edwin deposited money into a savings account that pays a simple annual interest rate of 1.4%. He

mafiozo [28]

<h3>The deposited sum of money by Edwin is $350.</h3>

Step-by-step explanation:

Let us assume that the amount deposited = P

The rate of interest = 1.4%

The Simple Interest earned = $24.50

Time = T = 5 years

Now, as we know:

SIMPLE INTEREST = $\frac{P \times R \times T}{100}$

$\implies 24.50 = \frac{P \times 1.4 \times 5}{100} \\\implies P = \frac{24.50 \times 100}{1.4 \times 5} = 350\\\implies P = 350$

Hence, the deposited sum of money by Edwin is $350.
