Answer: $54.50
Step-by-step explanation: If the bank account is currently overdrawn by $25.50, and then they deposit $20 per month for four months, they will have $54.50 in the account at the end of 4 months.
It is solved by multiplying 4 months x $20 = $80
Next, subtract (or add a negative) -$25.50 = $54.50
Answer:
s for length of either equal side
b for the unequal side
b=-2+2*(s+s) and 2s+b=40
b=2*2s-2
b=4s-2
2s+4s-2=40
6s-2=40
6s=42
s=7
b=4*7-2
b=28-2
b=26
Answer:
Your answer is 61.
Step-by-step explanation:
Simple enough! We simply round up each cost to the nearest whole dollar. $6.50 can be rounded to $7, $15.75 can be rounded up to $16, $2.25 can be rounded up to $3 (Note we're rounding up, in normal rounding we would round down to $2). Finally, $7.25 can be rounded up to $8.
Next comes simple algebra,
Therfore, your overestimate of the cost would be 61.
Answer:
1 to 30 seconds
Step-by-step explanation:
3 seconds increases your speed from 32 to 35 miles per hour
Hence 3 seconds = 3 miles per hour(35-32 miles)
1 second = 1 mile
The function for the increase per mile is therefore:
f(x)= 1x
Where x is number of seconds travelled on the highway
The domain of a function are the possible input values for x. Since the speed limit on the highway is 65 miles, the input values for x cannot be more than 30 seconds(current speed is 35 miles per hour, 65-35=30)
