Rapper DaBaby drove at a speed of 45 mph in front of Coosa High School on his way home from North Carolina. What was his speed i
NeTakaya
To find the answer, set up an equation:
\frac{45 \: miles}{1 \: hour}  \times  \frac{1000 \: meters}{1 \: mile}  \times  \frac{1 \: hour}{3600 \: seconds}  =
Using this set up we can cross out the units that are on opposite sides of the proportion such as miles and hours, leaving us with the desired units of meters and seconds. Then calculate m/s by multiplying 45 by 1000 meters and then dividing that value by 3600 seconds.

The resulting answer is 45mph = 12.5 m/s

Are you able to expand everything first? from there you would be able to combine line terms. basically if you have 3x+2x it would combine to 5x because they have x in them.

Joana spent $145 on groceries and after tax the final amount was $156.6. What was the tax rate​
777dan777 [17]

Answer:

8%

Step-by-step explanation:

Tax equals the original amount times the tax rate

We can find the tax by taking the amount he paid minus the original amount

tax = 156.6 - 145

tax = 11.6

tax = original amount * tax rate

11.6 = 145 * tax rate

Divide each side by 145

11.6/145 = 145/145 * tax rate

.08 = tax rate

To change this to percent, multiply by 100%

.08*100% = 8%
