I believe this is the complete problem.

Anton bought a picnic cooler. His total bill, with tax, was $7.95. He paid 6 percent sales tax. How much did he pay for the cooler alone without the tax? The cost of an item is 100% of its price. What number goes in place of ? in the addition problem?

The answer is the below:

He paid $7.473 without tax because $7.95 x 96% or (0.96) =$7.473

Answer:

The value of x is $7.5

Step-by-step explanation:

Given The cost of an item is 100% of its price.

Anton bought a picnic cooler. The total bill, with the tax, was $7.95. He paid 6% sales tax.

we have to tell how much he pay for cooler without tax.

We have to find the value of ? let it be x shown in expression.

By the given expression we can write

x+6% of x=$7.95

⇒ x(1+0.06)=$7.95

⇒ 1.06x=7.95 ⇒ x=7.5

Hence, the value of x is $7.5

He paid $7.5 without taxes.

you are given an 8-gallon jug filled with water and also two empty jugs: one that holds 5 gallons and other that holds 3 gallons

Yanka [14]

Answer:

Step-by-step explanation:

We will use following steps to measure exactly 4 gallons of water with the help of 5 gallons and 3 gallons empty jugs.

1). Fill 3 gallons jug completely.

2). Pour this 3 gallons of water into 5 gallons jug. Now we have 3 gallons of water in 5 gallons jug and 3 gallons jug empty.

We can add 2 gallons of water in the empty space of 5 gallons jug more.

3). Fill the 3 gallons jug with the water again.

4). Pour this water into 5 gallons jug which can hold 2 gallons of water more.

Now we have 5 gallons of jug filled fully and 1 gallon water remaining in the 3 gallons jug.

5). Empty the 5 gallons jug completely.

6). Pour the remaining 1 gallon of remaining water in 3 gallons jug into 5 gallons jug.

7). Fill the 3 gallons jug completely and pour it into 5 gallon jug.

8). Finally we have 4 gallons of water in the 5 gallons jug.

Rhe sum of three consecutive ofd numbers is 87. What is the smallest of these numbers?

neonofarm [45]

Answer:

The smallest of the said odd numbers is 27

Step-by-step explanation:

Since it is 3 odd numbers that sums up to 87, the first thing to do is to divide 87 by 3

That is 87/3 = 29, which is an odd number

The nearest odd numbers to 29 are 27 and 31, and the total of all these three odd numbers is 87

That is 27+29+31 = 87, which are consecutive odd numbers.

The smallest odd number here is therefore 27

Which of the following is an inequality sentence?

ziro4ka [17]

Answer:

$C. x$

Step-by-step explanation:

Option A $[x+5=20]$ tells us that: When we add 5 to a variable x, we get 20. As it has a unique value for x and is completely equal to it(i.e. 15), It is an equality.

Option B $[x=5]$ tells us that: A variable x equals to 5. Hence, as x is unique for 5 and is wholly equal to it, it's an equality too.
Option C $[x$ tells us that: A variable x isn't 5 but lesser than it. As we cannot equate it to 5, nor we are given the nature of the variable x, it is an Inequality.
Option D $[x+5]$ is an expression; It can't be called an equation or an inequality unless we relate it with another expression.
