The answer is C. Divide 60 by 1.25 to get x alone and you'll have 48 hotdogs. To check, multiply 48 by 1.25 and you'll get 60.
Answer:
(-6,2)
Step-by-step explanation:
An ordered pair is a solution if when substituted it makes the equation true. If when you substitute, it does not make the equation true then it is not a solution.
-3x - 7y = 4
Substitute:
-3(-5) - 7(2) = 4
15 - 14 = 4
1 = 4 FALSE
-3(2) - 7(-5) = 4
-6 + 35 = 4
29 = 4 FALSE
-3(2) - 7(-6) = 4
-6 + 42 = 4
36 = 4 FALSE
-3(-6) - 7(2) = 4
18 - 14 = 4
4 = 4 TRUE
Pentagons have five sides, so 5x = 20. Only value for x that makes this true is 4, so 4 cm per side.

Answer:
The approximate number of gallons of water that flow over the waterfall in 1 day is:
Step-by-step explanation:
To obtain the answer to the question, you must multiply the number gallons of water flow over a waterfall each second (6.5 x 10^5 gal/s) by the number of seconds in a day (8.6 x 10^4 s), as I show you below:
- Gallons of water that flow over the waterfall in 1 day = Number of gallons * Number of seconds in a day.
- Gallons of water that flow over the waterfall in 1 day = 6.5 x 10^5 gal/<u>s</u> * 8.6 x 10^4 <u>s</u>
Now, we must cancel the seconds, then:
- <u>Gallons of water that flow over the waterfall in 1 day = 5.59 x 10^10 gallons</u>
How you can see, <em>once you have multiplied these two values, the answer is the same to the option A</em>.
