A taxi charges $2.50 for each ride plus $1.25 per mile traveled.
If the total charge for one ride was $8.75, how many miles
were traveled?
Answers
Answer:
5 miles
Step-by-step explanation:
We have to figure out how many times $1.25 was charged. First, we have to do 2.50 + 1.25 = 3.75 + 1.25 = 5 + 1.25 = 6.25 + 1.25 = 7.5 + 1.25 = 8.75
We charged $1.25 5 times, so this means that it was 5 miles.
Answer:
5 miles
Explanation:
this is because if you subtract 2.50 from 8.75 then you will be left with 6.25. after you do this then you divide 6.25 by 1.25 and this will give you 5 miles.

Answer:
(-13)^2= (15* -11 + -4) = -169
Step-by-step explanation:
Replace all occurrences of + − with a single − . A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign
because1 x −1 = −1
(−13)^2=15 x −11 −4
Raise − 13 to the power of 2 .
169=15 x −11 −4
Multiply 15 by −11.
169 = −165 − 4
and finally Subtract 4 from−165.
169 = −169
if its (-13)^2 / (15*-11+-4) as the orginal post did not say divided, the answer would be -1 hope his helps.

Answers
Answer:
(c+3b)/8 = a
Step-by-step explanation:
c = 8a -3b
Add 3b to each side
c +3b = 8a-3b+3b
c +3b = 8a
Divide each side by 8
(c+3b)/8 = 8a/8
(c+3b)/8 = a
Explanation: c=8a-3b, if you're wanted to solve for a you need to subtract 8a from both sides, c-8a=-3b then subtract c from both sides, -8a=-3b-c then divide both sides by -8 a=3/8b+c/8

Laurie earns $7.50 per hour at the fruit stand plus an extra $2.00 per hour on Sundays. One week in August, she worked on Sunday, Monday, and Wednesday. She worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, how many hours did Laurie work on Monday? Enter and solve an equation.
Answers
Answer:
Hi there!
Your answer is:
She worked for 3 Hours on Monday.
Step-by-step explanation:
7.5$ per hour
7.5+2$ per hour on Sundays.
In August:
Sunday, Monday, Wednesday.
# of hours for Monday =Wednesday
Sunday= 4 hrs (which would mean 9.5$ * 4)
Monday and Wednesday will be modeled by X
X + 38$ (earned sunday)= 83$
-38
X= 45$
Since X represents BOTH monday and wednesday, divide by 2
45/2 = 22.5$
CHECK YOUR WORK
22.5$ (monday) + 22.5$ (wednesday) + 38$ (sunday)= 83???
45=38=83???
83=83 YES
Now, to determine how many hours that is, we divide the earned wages by the wage per hour.
22.5 / 7.5 = 3 HOURS
CHECK YOUR WORK
3 hours * 7.5 per hour = 22.5???
22.5 = 22.5 YES
Hope this helps
If she worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, the number of hours that Laurie work on Monday will be: 3 hours
$7.5= 1 hour Other days
$9.50 or ($7.50+$2.00) = 1 hour Sunday
Let Sunday= 4×$9.50 =$38
Let Monday= x × $7.5=$7.5x
Let Wednesday= x × $7.5=$7.5x
Let Total earning=$83
Let x represent the number of hours
Hence:
First step is to formulate
7.5x+7.5x+38=83
Second step is to calculate how many hours did Laurie work on Monday
x =83-38÷ 7.5+7.5
x=83-38÷15
x=45÷15
x=3 hours
Inconclusion If she worked the same number of hours on Monday and on Wednesday. On Sunday she worked 4 hours. If she earned a total of $83.00 for the week, the number of hours that Laurie work on Monday will be: 3 hours

The surface area of the cube, in inches² is 96in²
The formula for calculating the surface area of a cube is expressed as:
S = 6L²
L is the side length of the cube
Given that L = 4in. Substitute the given parameter into the formula:
S = 6(4)²
S = 6(16)
S = 96in²

Answers
Explanation. We know that a positive multiplied by a negative (or vice versa) equals a negative. If it’s confusing, you can even take out the negative and add it at the end. Remember, 1 negative means the answer is negative, 2 negatives means the answer is positive, and two positives are just positive (this is used for multiplication and division ONLY). So, to solve, 5•3 is 15, and just make it negative, -15!
