Answer:

4x +8= 20

2x+3= 9

Step-by-step explanation:

4 times 3 equals 12 and 12+8 = 20

2 times 3 is 6 and 6+3=9

Answer:

4x+8=20

2x+3=9

Step-by-step explanation:

I used substitution.

I substituted x with 3 so

4(3)+8=20

same with the other one,

2(3)+3=9

Hope this helped!

Hey there! Let's break this answer down.

1. If he bough 3 pounds of cement for $27.75 each, that 3x27.75, which is $83.25. So he spent $83.25 on cement.

2. Next, add $12.58 for the cost of the plant to $83.25, which $95.83.

3. Finally, he paid $8.99 for the sales tax. When adding that to $95.83, we get $104.82.

So, his total was $104.82.

Have a great day!

Answer:

104.82

1Step-by-step explanation:

27.75 times 3 equals 83.25 plus 12.58 equals 95.83 then add 8.99 which is $104.92

Answer:9

Step-by-step explanation:

I did the math

Given:

Able's age can be represented by x.

Able's sister is 4 years younger than him.

Able's older brother is twice as old as he is.

The combined age of all three siblings is 32.

To find:

The age of Able's younger sister.

Solution:

Able's age can be represented by x.

Able's sister is 4 years younger than him.

Age of Able's sister = (x-4)

Able's older brother is twice as old as he is.

Age of Able's older brother = 2x

The combined age of all three siblings is 32.

Add 4 on both sides.

Divide both sides by 4.

The age of Able is 9 years. So, age of his younger sister is

Therefore, the age of Able's sister is 5 years.

Answer:

20

Step-by-step explanation:

(20 books / 2) * 3 = 30 minutes

Given problem:

 What is 9*5;

 The formula P*Q  = P x Q  - 7;

To  find 9*5, simply make P = 9 and Q = 5

Input into the equation and solve;

   P*Q  = P x Q  - 7    =   9 x 5 - 7

                                 = 45 - 7

                                 = 38

The solution to this problem is 38.

Answer:

A) d(r) = 2r

Value when r = 5 is 10 ft.

diameter is 10 ft when the radius is 5ft

B) A(r) = πr²

Value when r = 5 is 25π ft²

Area is 25π ft² when radius is 5 feet

C) C(r) = 2πr

Value when r = 5 is 10π

Circumference is 10π when radius is 5 feet

Step-by-step explanation:

A) Using function notation, since d = 2r

d(r) = 2r

d(5) = 2(5)

d(5) = 10 feet

This means that the diameter is 10 ft when the radius is 5ft

B) Area = πr²

In function notation, its;

A(r) = πr²

When radius is 5 feet,

Area is; A(5) = π(5²) = 25π

It means Area is 25π ft² when radius is 5 feet

C) Circumference is 2πr

In function notation, it's;

C(r) = 2πr

When r = 5 feet,

Circumference is;

C(5) = 2π(5)

C(5) = 10π
