Answer:
sixty miles over four gallons
Step-by-step explanation:
The “over” word means divide, so let’s change all of these choices into expressions and evaluate them:
thirty miles over three gallons -> 30 mi/3 gal = 10 mi/gal
three gallons over thirty miles -> 3 gal/30mi = 1 gal/10 mi = 0.1 gal/mi (because it is asking for unit rate)
four gallons over sixty miles -> 4 gal/60 mi = 15 gal/mi
sixty miles over four gallons -> 60 mi/4 gal = 15 mi/gal
The problem is asking for which unit rate is equivalent to 15 mi/gal. We see that this fits the last choice (the value and the units). Therefore, the last choice is our answer.
I hope this helps! :)
There are 10 ways you can pic the first, 9 ways to pick second, and 8 left to pick the third so there are a total of 10•9•8= 720 ways
Check out the image attachment for one way to draw this problem out. Notice how angles AEC and DEB are vertical angles, so that means they are congruent angles
(measure of angle AEC) = (measure of angle DEB)
6x + 20 = 10x
6x + 20-6x = 10x-6x ... subtract 6x from both sides
20 = 4x
4x = 20
4x/4 = 20/4 ... divide both sides by 4
x = 5
The value of x is 5.
Let's check the answer
6x + 20 = 10x
6*5 + 20 = 10*5 ... replace every x with 5
30+20 = 50
50 = 50
We have confirmed the answer.
Answer: X=5
Step-by-step explanation: If PQ equals 30 then PM will equal half of PQ. Which means that PM will equal 15, which means x= 5 because 3 times 5 equals fifteen.
