16x = 180 - 5 + 1

16x = 176

x = 176/16

x = 11

Answer 2

Step-by-step explanation:

(7x-1)+(9x+5)=180 ( since its a straight line )

16x+4=180

x= 11

Kelly bought 8 boxes of sunglasses at a swap meet. Each box had 15, 20, or 25 pairs in it. Kelly estimates a reasonable number of sunglasses to be 110.

Is this a reasonable estimate?

Answers

Answer:

Step-by-step explanation:

Because 8 * 15 = 120 so even if they all had 15 in hem here would be at LEAST 115

No. The reason is that if all the boxes had even 15 pairs in them, the least amount, it would be 120 not even 110. An ideal estimate would be something in between 200 and 120.

the number of calories in a container of milk is directly proportional to the amount of milk in the container. if there are 160 calories in an 8-ounce glass of milk, find the number of calories in a 15-ounce of milk?

Answers

Answer:

300

Step-by-step explanation:

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

160 calories = 8-ounce glass of milk

300 calories = 15-ounce glass of milk

The number of calories in 15-ounce of milk is 300 calories.

What is a unit rate?

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

In 30 minutes, a man walk for 1.5 miles.

We have,

160 calories = 8-ounce glass of milk

Multiply 15/8 on both sides.

15/8 x 160 calories = 15/8 x 8-ounce glass of milk

15 x 20 calories = 15-ounce glass of milk

300 calories = 15-ounce glass of milk

Thus

160 calories = 8-ounce glass of milk

300 calories = 15-ounce glass of milk

The number of calories in 15-ounce of milk is 300 calories.

If 5 of mathjuce contain 120grams of sugar how many grames of suger are in a case of 24 cans of mathjuce

Answers

Answer: 576 grams of sugar

Explanation: To solve this, you must do this following. First, you'd need to divide the 5 cans of MathJuice by their grams of sugar content. By doing this, you will find out how many grams of sugar are in each can. So, you'd divide 120 by 5 and get 24. This means that there are 24 grams of sugar in each can. Now, you'd need to multiple that by the number of cans in a case of MathJuice. You need to multiply 24 by 24. Doing this will get you a product of 576. Therefore, there are 576 grams of sugar in a case of MathJuice.

How long would it take for a car to travel 200 km if it has an average speed of 55 km/hr?

Answers

Answer:

11,000 km/hr

Step-by-step explanation:

Distance= speed x time

time= 55 km/hr

speed= 200 kn

=200 km x 55 km/hr

= 11,000 km/hr

At an average speed of 55 km/hr the car will cover a distance of 200 km

in 3.6 hours.

What is a unitary method?

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

We know, distance = speed×time or d = st.

Given, A car to travel 200 km if it has an average speed of 55 km/hr.

Therefore, From d = st we have,

200 = 55t.

t = 200/55.

t = 3.6 hours.

What is the relative speed between two moving objects?
