Math is used to help calculate certain things such as taxes and such, but they are mostly important for jobs since certain jobs require knowledge of math. Jobs such as working in a branch of engineer, architecture, etc.
No, they are not equivalent. The first term, -4 1/2 equals 4 whole units and one half unit. All negative. So it’s like you have someone 4 and 1/2 dollars.
The second term, (-4)1/2 means multiplying -4 times 1/2. Doing the multiplication for this gives you -4/2. Solving the division here is -2. It’s taking away 1/2 dollar 4 times.
I hope this helped. Happy to answer any questions you have.
Answer: The driver has $95.25 after the last ride.
Step-by-step explanation: First we need to know how much money he recieved from each ride. Multiply 3.5 with each number.
$3.5 x 10 = $35
$3.5 x 5.5 = $19.25
$3.5 x 19 = $91
Now add them up.
$35 + $19.25 + $91 = $145.25.
However, he spends $50 on gas. So subtract $145.25 and $91.
$145.25 - $91 = $95.25.
Therefore, the driver has $95.25 after the last ride.
Answer:
-3
Step-by-step explanation:
Note the parts of the equation:
y = mx + b
y = (x , y)
m = slope
x = (x , y)
b = y-intercept
In this case: y = 4x - 3
x = x
y = y
m = slope = 4
b = y-intercept = -3

Answer: billboards with 4 lines for $40 (quantity of 4)
Step-by-step explanation:
We have to take the number of dollars Sara spent (d) and divide by the number of the amount of billboards Sara bought (4). We also know Sara bought 4 billboards.
- We know one billboard with 6 lines is $30
- We know one billboard with 4 lines is $40
Now, we have to take the number 160 and divide by both numbers: 30 & 40
160 ÷ 6 = 26.66667
We have to remember the fact that Sara bought 4 billboards.
160 ÷ $40 = 4
The answer to the question is billboards with 4 lines for $40 with a quantity of 4.
