Answer:

90

Step-by-step explanation:

x8=717

This can also be written as

8x=717

Divide both sides by 8

8x/8=717/8

x=717/8

x=89.625

We are to round up to the nearest ten. In rounding of numbers, numbers 1 to 4 are rounded up to 0 while numbers 5 to 9 are rounded up to 1.

Numbers can be rounded up to nearest ten, nearest hundred, nearest thousand. Numbers can also be rounded up to 1 decimal place, two decimal place, three decimal place, etc.

Rounding off 89.625 to the nearest ten. The unit before the tenth digit is 9, hence 9 would be rounded up to 1, and then added to the tenth digit, which is 8 to give 9.

Hence the answer is 90

What is the distance between -45 and 65
tatyana61 [14]

Answer:

110

Step-by-step explanation:

What is the Difference between -45 and +65? In other words, what is the Difference between negative 45 and positive 65?

To solve this math problem, start by picturing a horizontal number line that starts with negative infinity on the left and ends with positive infinity on the right:

∞ ..... -3, -2, -1, 0, +1, +2, +3, .... ∞

The Difference between -45 and +65 is the distance between -45 and +65 on our number line above. Thus, the Difference between two numbers will always be a positive number.

It is a two-step process to calculate the Difference between -45 and +65. Step 1 is to subtract +65 from -45, and Step 2 is to find the absolute value of the Step 1 answer. Here is the math to illustrate better:

(-45) - (+65) = -110

|-110| = 110

That's it! The Difference between -45 and +65 is as follows:

110

Mrs. Mott called two companies about getting new uniforms for the soccer team. The first company she called charges $70 per unif
Fittoniya [83]

Answer:

For less than 7 uniforms.

Step-by-step explanation:

The first company she called charges $70 per uniform.

So, the cost of x uniforms will be $70x.

The second company she called charges $280 plus $30 per uniform.

So, the cost of x uniform will be $(280 + 30x).

Now, if the total cost of purchasing x number of uniforms from the first company is less than that from the second company then, we can write the inequality equation as  

70x < 280 + 30x

⇒ 70x - 30x < 280

⇒ 40x < 280

⇒ x < 7

Therefore, for less than 7 uniforms the cost from the first company will be less than the cost from the second company. (Answer)
