Answer:

45b + 43 cents

Step-by-step explanation:

45b + 43 cents

Answer:

Value of stamp collection = (45b + 43) cents

Step-by-step explanation:

What we have here is as follows;

if there are x 3-cent stamps, then there are 4x 10-cent stamps

So the number of 2-cent stamps is 1 less than 3 cent stamps and that will be x-1 2 cent stamps

Number of 2 cents stamps = b

This means that x-1 = b

Thus, x = b + 1

So the value of the stamp collection is as follows;

x 3 cents stamps = 3(b+ 1) = 3b + 3 cents

4x 10 cents stamps = 10(4(b + 1)) = 10(4b + 4) = 40b + 40

value of the 2 cents stamp = 2b cents

Total value is thus;

2b + 40b + 40 + 3b + 3 = (45b + 43) cents

The equivalence of the equation is 5x + 48 = 5x + 3.

Since 48 cannot be equal to 3, hence there are no solution.

<h3>What is the value of x?</h3>

Given the equation; x-4[ x - 2( x + 6) ] = 5x + 3

We remove the parentheses

x-4[ x - 2( x + 6) ] = 5x + 3

x-4[ x - 2x - 12 ] = 5x + 3

x - 4x + 8x + 48 = 5x + 3

5x + 48 = 5x + 3

We can go further and collect like terms

5x - 5x + 48 = 3

48 ≠ 3

Since 48 cannot be equal to 3, hence there are no solution.

Find the area and the circumference of a circle with a diameter 8yrd.
nalin [4]

Answer:

Part 1) The area of the circle is A=50.24\ yd^2

Part 2) The circumference of the circle is C=25.12\ yd

Step-by-step explanation:

step 1

The area of a circle is equal to

A=\pi r^{2}

we have

r=8/2=4\ yd ---> the radius is half the diameter

\pi =3.14

substitute

A=(3.14)(4)^{2}

A=50.24\ yd^2

step 2

The circumference of a circle is equal to

C=\pi D

we have

D=8\ yd

\pi =3.14

substitute

C=(3.14)8

C=25.12\ yd
