Im pretty sure its 8y because two negatives equal a positive so 5 plus 3 and then you isolated the y so 8y. :)
Answer:
A police chase covering 225 miles at a constant speed of 75 miles/hour will last 3 hours.
Step-by-step explanation:
If the car is traveling at a speed of 75 miles/hour and has traveled a distance of 225 miles, we can solve for the time taken by using the equation
d = r*t
where d is our distance in miles
r is the rate of travel in miles/hour, and
t is the time taken in hours
In this case,
d = 225 miles, and
r = 75 miles/hour
Let's plug these into our equation
225 miles = (75 miles/hour) * t Divide both sides by 75 miles/hour
Our miles units will cancel out, leaving us with
3 hours = t
Therefore, a police chase covering 225 miles at a constant speed of 75 miles/hour will last 3 hours.
There is two hundred and four (204) on a standard chessboard.
Answer:
About 91 customers would be expected to pay with a credit card.
Step-by-step explanation:
Well you have ro set up a ratio of 16/70 = x/400
This way the amount of people that used a credit card out of all of the people that came and you can figure out the amount of people that will use a credit card out of the 400 people that are expected tho come. You multiply like a butterfly. 70 times x and 400 by 16. Then you will get 6,400=70x divide both sides by 70 and get 91.42=x so if ypu round, 91 people are expected to pay using a credit card out of the 400 customers that are expected to come.
Answer:
Step-by-step explanation:
Let's solve your equation step-by-step.
−19=b−6
Step 1: Flip the equation.
b−6=−19
Step 2: Add 6 to both sides.
b−6+6=−19+6
b=<em>−13</em>
