58 miles per hour, because you would divide 145 by 2.5 to get how many miles were covered in one hour
Hello,
Shall we begin?
4210.....................100%
911.47..................x
4210x = 100*911.47
4210x = 91,147
x = 91,147/4210
x = 22%
take-home pay
= 100%-22%
= 78%
Answers: 78%
x-4 needs to be greater or equal to zero so
[4, ∞) is the answer
Answer:
Y= 3.2b + 100
Step-by-step explanation:
That is the equation needed to find the value of b. since Omar bought the cup at the fixed price of 100 we know that no matter what the answer has to be over 100. So that becomes our Y intercept. 3.2 percent is how much the price inflates every year.
Answer:
21 students were in the class.
Step-by-step explanation:
The information in the question tells you that 4/7 of the class is girls.
That means that the remainder of the class is 1 - 4/7 = 3/7 boys
Let the total in the class = x
(3/7)x = 9 Multiply by 7
(3/7)*7*x = 9 * 7 Simplify the right and left
3x = 63 Divide by 3
3x/3 = 63/3
x = 21
There were 21 students in the class.
