Answer:
B.35
Step-by-step explanation:
The sequence is
14, ,56,....
14 , x , 56
Think of it as 14 + d = x
x+ d = 56
d is the common difference
We now have 2 equations and 2 unknowns
Substitute the first equation in for x into the second equation
x+d =56
(14+d) +d = 56
Combine like terms
14 + 2d = 56
Subtract 14 from each side
14-14 + 2d = 56-14
2d = 42
Divide by 2
2d/2 =42/2
d = 21
The common difference is 21
Now we can find x
14 + d = x
14+ 21 = x
35 =x
The unknown term is 35
Answer:
<h2>J{(0,8),(1,7),(2,6)}</h2>
The numbers are 5 and 12.
Smaller number = x
Larger number = y
x +y =17
y = 3x - 3
x +3x -3 = 17
4x = 20
x = 5
smaller number is 5
y = 3(5) - 3
y = 12
larger number is 12.
Answer:
Speed= 67.5 miles per hour
Step-by-step explanation:
Google maps has told Juanita that her car trip will be 32 miles.
Juanita has already gone 14 miles.
Remaining miles left to travel
= 32-14
Remaining miles left to travel
= 18 miles
She has only 16 minutes to reach her destination.
The required speed for her to reach her destination
= Distance/time
Her time = 16 minutes
Her time = 16/60
Her time =4/15 hours
Speed= distance/time
Speed= 18 /(4/15)
Speed=18* 15/4
Speed= 67.5 miles per hour
Answer:
$50
Step-by-step explanation:
If the original price was $10 more than the sale price, so we know that in this case, 20% = $10. Because 20% is equivlalent to 
, multiply $10 by 5 to get the answer of $50.
