Step-by-step explanation:
c !!
Answer:
Solve for g:
10 - 4 g = 20 - 4 g
Subtract 10 - 4 g from both sides:
0 = 10
Hint: | Look for a false statement.
0 = 10 is trivially false:
Answer: (no solutions)
Step-by-step explanation:
Given :
Distance travelled , d = 180 miles.
Time taken , t = 4 hours.
To Find :
Speed in feet per minutes.
Solution :
Distance in feet is , d = 180×5280 = 950400 feet.
Time taken , t = 4×60 = 240 minutes.
Speed is given by , 
Hence, this is the required solution.
Answer: Sylvia should use 35 pounds of Kona coffee and 65 pounds of Columbian coffee
Step-by-step explanation:
Let x represent the number of pounds of Kona coffee that Sylvia should use.
Let y represent the number of pounds of Columbian coffee that Sylvia should use.
Sylvia wants to mix 100 pounds of Breakfast Blend coffee. This means that
x + y = 100
She is using two types of coffee to create the mixture. Kona coffee sells for $51 per pound and Columbian coffee sells for $11 per pound and the mixture would sell for $25 per pound.
This means that
51x + 11y = 2500 - - - - - - - - 1
Substituting x = 100 - y into equation 1, it becomes
51(100 - y) + 11y = 2500
5100 - 51y + 11y = 2500
- 51y + 11y = 2500 - 5100
- 40y = - 2600
y = - 2600/-40
y = 65
x = 100 - y
x = 100 - 65 = 35
Answer: 0.12
Step-by-step explanation:
There are 65 candy bars. Out of that;
2 candy bars have 300 to 350 calories
1 candy bar has 350 to 400 calories
4 candy bars have 400 to 450 calories
1 candy bar has 450 to 500 calories
The total proportion out of 65 candy bars that have over 300 calories is;
= ( 2 + 1 + 4 + 1) / 65
= 8/65
= 0.12
