Three equivalent ratios that are associated with this rate would be 6 gallons/1min, 360gallons/1 hour and 720 gallons/2hours.
I'm sorry but I can't explain or show how to use a double number line for this question.
Answer:
x(x)=1/4(30+60+x)
Step-by-step explanation:
minutes spent on math homework= x
minutes spent on history homework= 30 min
minutes spent on English homework= 60 min
Total minutes spent on homework = x+30 +60
Also
x= 1/4(x+30 +60)
x= x/4 + 90/4
x-x/4= 90/4
(4x-x)/4=90/4
3x=90
x=30
Hence time spent on maths=30 min
total time spent= 30+60+30
= 120 min
1/4 of 120 min= 30 mins!
Y = -2x + 5
All you have to do when coming across this type of problem is substitute x and y for the points given, as well as change whatever b is, in this case 5, for b. For example: -3 = -2(4) + b
Answer:
Yes
Step-by-step explanation:
Yes. Explanations vary. Sample explanation: The weight itself doubles, so
any measurement of the weight using the same units will also double. We
can also see that by saying if the weight is x pounds, then double that weight
would be 2x pounds. The weight in kilograms will be x ÷ 2.2, and the double
weight will be or (2x) ÷ 2.2 2(x ÷ 2.2), which is also double.
