A set of golf clubs is on sale for $150.00, which is 70% off of its original price. What was the original price of the golf clubs?

Answers

Answer:

\$500

Step-by-step explanation:

Let

x------> the original price of the golf club

we know that

100\%-70\%=30\%

30\%=(30)/(100)=0.30

0.30x=150 ------> linear equation that can be used to find the original price

solve for x

Divide by 0.30 both sides

0.30x/0.30=150/0.30

x=\$500
Since it is 70% OFF, then $150.00 is 30% of the original price.

Divide it all by 3,
$50.00 is 10%,
therefore $500.00 is the original price!

Answers

Answer:

As per the statement:

At the grocery store kayla buys 1(1)/(3) = (4)/(3) pounds of ground Turkey.

⇒Ayla buys = (4)/(3) pounds of ground turkey.

It is also given that Tasha buys 2 times as much ground Turkey as Kayla .

2 times as much as ground turkey as Kayla means 2 * (4)/(3) = (8)/(3) pounds.

⇒ Tasha buys ground of turkey = (8)/(3) pounds.

Therefore,  (8)/(3) pounds ground of turkey does tasha buy.

It 42

42 would be the greatest amount of chairs in a row. This is a very simple question. All you have to do is find the GCF using a method such as birthday cake/ladder or prime factorization. Using this, you can find the GCF to be 42.

Use what you know about rounding to solve the problem.The halfway point between 30 and 40 is 35.

number has 6 digits smallest digit is 0.01 largest digit is 8,000 digit in the tens is 2 less than digit on the hundreds the sum of tens and hundreds is the digit in the thousands the digit in the tenths has the same value in every place the remaining digit is the largest even number

Answers

What a problem!  We know that the largest digit is 8,000, and the smallest is 0.01.  The number is 8,_ _ _._1.  If the tens is 2 less than the hundreds digit, then if we make the hundreds digit x, the tens are x-2.  The tens digit plus the hundreds digit is the thousands digit, so x+(x-2)=8.  Let's solve: x+(x-2)=8.  Eliminate parentheses: x+x-2=8.  Use inverse operations:x+x-2+2=8+2.  x+x=10.  Combine terms: x+x=2x.  2x=10.  Divide: 2x/2=10/2.  x=5.

So the hundreds digit, x, is 5.  And the tens are x-2: 5-2=3.  The number is 8,53_._1.  And what's the only number that means the same, no matter what place value you put it in?  0!  This is the tenths place: 8,53_.01.  The remaining digit is the ones.  The largest one-digit even number is 8, so our number is 8,538.01!

Answer: 8,538.01
