7n-22 ≥ 64
1. Move constant to the right.
7n ≥ 64 + 22
2. Combine like terms.
7n ≥ 86
3. Divide 7n by 7 to get n alone.
n ≥ 86
4. Divide 86 by 7.
n ≥ 86 / 7 OR n ≥ 12.29
Answer:
Area = w x (5+ 8 w)
Step-by-step explanation:
Recall the formula for the area of a rectangle: Area=with x length
You are suggested to use "w" to represent the width of the pen.
Now, they give you information about the length of the pen in word form.
We are converting those words into an algebraic expression:
"The length of the pen is 5 more than 8 times the width of the pen"
Length = 5 + 8 w
So we replace the length of the pen with this expression in the area formula:
Area = w x (5+ 8 w)
The correct answer is C) 0.56
Explanation:
In general terms, the probability of two or more events can be calculated by adding the probability of each event. This rule applies when an event is considered as mutually exclusive. Age is considered as a mutually exclusive event because if a random individual is selected he/she will be only one age. In this context, if you need to know the probability that a student is 15 or younger it is necessary to add the probability that a student is 15, the probability that the student is 14, and the probability that the student is 13. The process is shown below:
P (A or B or C) = P(A) + P(B) + P(C)
P = P(13) + P(14) + P(15)
P= 0.001 + 0.25 + 0.30
P= 0.56
Answer:
Hank's pickup need 3 gallons of gas to travel 54 miles.
Explanation:
Hank's pickup can travel 72 miles on 4 gallons of gas
Miles travel by Hank's pickup with 1 gallon of gas = 72/4 = 18 miles.
We need to find gallons of gas required for Hank's pickup to travel 54 miles.
Gallons of gas required = Miles need to travel/ Miles travel with 1 gallon of gas
= 54/18 = 3 gallons of gas.
So Hank's pickup need 3 gallons of gas to travel 54 miles.
