The total number of pencils is 2,160. When estimating to the nearest hundredth one gets 2,200, which is an underestimate.
The advantage of underestimating is that your answer is more accurate than an overestimate.
Answer:
2.25 cups
Step-by-step explanation:
There are 5 eights in 40.
1.25 × 5 = 6.25
1.5 × 5 = 7.5
1 × 5 = 5
1 quart = 4 cups
6.25 cups - 4 cups = 2.25 cups
Let's translate your words into numbers and fractions. So it's
5/4 - 1/x - 2 = -4/-4.
Let's Simplify it first by eliminating -4/-4, the answer will be 1 since negative divided by negative is positive and 4 divided by 4 is 1.
5/4 - 1/x - 2 = 1
Then Get the GCF of the equation which is 4x.
Then divide the whole equation by 4x and it would be,
<span><u>5/4 - 1/x - 2 = 1
</u></span> 4x
Then it will look like this, 5x-8x-4 = 4x
Then transpose, 5x - 8x - 4x = 4
Simplify by deducting the left side. -7x = 4
Then divide both sides by -7.
Then the final answer would be x = -4/7
Answer:
54mph
Step-by-step explanation:
To find the speed in "miles per hour" or miles/hour, divide the number of miles by number of hours.
1080 miles/20 hours
= 54miles/hour
His speed is 54 miles per hour.
