Y+6=3y-30

Subtract y from the left

6=2y-30

Add 30 to both sides

36=2y

Divide by 2

18=y

2x+29=4x-47

Subtract 2x

29=2x-47

Add 47

76=2x

Divide by 2

eighteen 2.5- gallon buckets are needed to fill a cistern of water

How many 3-gallon buckets of water will fill the cistern.

Answers

Answer:

15 3-gallon buckets of water will fill the cistern

Step-by-step explanation:

Eighteen 2.5- gallon buckets are needed to fill a cistern of water

This means, 2.5 gallon buckets in 18 places

2.5 gallons × 18 = 1 cistern of water

45 gallons = 1 cistern of water

How many 3-gallon buckets of water will fill the cistern.

Number of 3-gallon bucket in a cistern = Total gallons of bucket in one cistern / 3-gallon buckets

= 45 gallons / 3-gallon buckets

= 15

Number of 3-gallon bucket in a cistern = 15

15 3-gallon buckets of water will fill the cistern

Answers

23$.
In 8 months it will cost 1/3 its original price so you multiple the original price by 1/3.
69.00*1/3
This is the same as dividing by three so just divide 69 by 3 and you get 23.

Calculate the average rate of change for the given graph from x = 3 to x = 5 and select the correct answer below.

Answers

Answer:

Average rate of change between x = 3 to x = 5 is 0.

Step-by-step explanation:

Given quadratic function s passing through two points (3, 0) and (5, 0).

Average rate of change of a function between x = a and x = b is given by,

Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]

From the graph attached,

Average rate of change between x = 3 to x = 5 will be,

= [tex]\frac{f(5)-f(3)}{5-3}[/tex]

= [tex]\frac{0-0}{5-3}[/tex]

= 0

Therefore, average rate of change between x = 3 to x = 5 is 0.

Answer: The average rate of change for the given graph from x=3 to x=5 is 0

A customer has a credit card that charges 18% simple interest every year. How much interest will the customer save
by paying off a credit card debt of $5,000 at the end of 1 year instead of at the end of 3 years?

Answers

The customer will save interest by paying off a credit debt is $1,800 at the end of 1 year instead of at the end of 3 years

What is simple interest?

Simple interest is the concept that is used in many companies such as banking, finance, automobile, and so on.

A customer has a credit card that charges 18% simple interest every year.

The customer saves by paying off a credit card debt of $5,000 at the end of 1 year instead of at the end of 3 years.

Interest for three years will be

[tex]\rm A_3 = \dfrac{PRT}{100}\\\\\\A_3= \dfrac{5000*18*3}{100}\\\\\\A_3= 2700[/tex]

Interest for one year will be

[tex]\rm A_1 = \dfrac{PRT}{100}\\\\\\A_1= \dfrac{5000*18*1}{100}\\\\\\A_1= 900[/tex]

The saved amount will be

A = A₃ - A₁

A = 2700 - 900

A = 1800

The customer will save interest by paying off a credit debt is $1,800 at the end of 1 year instead of at the end of 3 years

Write a quadratic equation with 7 and as its roots. Write the equation in the form ax^2+ bx + C = 0,
where a, b, and c are integers.

Answers

x^2 - 37/5x + 14/5

The equation in the form ax² + bx + c of the quadratic equation with 7 and 2/5 as it root is x² - 33 / 5 x + 14 / 5

The root of the quadratic equation are 7 and 2/5 .

The equation should be written in the form

ax² + bx + c

where

a, b and c are integers.

Therefore,

x - (7) and x - 2/5

(x - 7)(x - 2/5)

open the bracket

x² - 2/5x - 7x + 14 / 5

express 0.0003 in Scientific notation by counting decimal places

Answers

Answer:

When we write numbers in scientific notation, we must put the first non-zero digit ahead of the decimal.  In this case, the decimal would be behind the 3. Because we moved the decimal places four times to the right, our exponent will be 4. Thus,

3.00 x 10⁻⁴

we can express 0.0003 as 3 × 10⁻⁴ in scientific notation.

To express 0.0003 in scientific notation, we count the number of decimal places from the original number until we have a single non-zero digit before the decimal point. In this case, we have four decimal places before the non-zero digit (3).

Thus, we can express 0.0003 as 3 × 10⁻⁴ in scientific notation. The negative exponent (-4) indicates that we move the decimal point four places to the left to obtain the original value.

In summary, by counting the decimal places, we can express 0.0003 as 3 × 10⁻⁴ in scientific notation.
