The Apache Taxi Company charges $2.50 to pick up a passenger and then adds $1.95 per mile. Isaac was charged $27.46 to go from one city to another. If x represents the number of miles driven by the taxi, which linear equation can be used to solve this problem, and how many miles did Isaac travel, rounded to the nearest tenth?

Answers

Answer:  Isaac traveled approximately 13 miles by the taxi.

Step-by-step explanation:

Since we have given that

Amount charges to pick up a passenger = $2.50

Amount per mile = $1.95

Total amount charged = $27.46

Let x be the number of miles driven by the taxi.

According to question, it becomes,

2.50+1.95x=27.46\n\n1.95x=27.46-2.50\n\n1.95x=24.96\n\nx=(24.96)/(1.95)\n\nx=12.8\n\nx\approx 13\ miles

Hence, Isaac traveled approximately 13 miles by the taxi.

27.46 - 2.50 = 24.96 / 1.95 = 12.8 miles

Compute the distance between the two points. (3, 7) and (0, 0)

Answers

Answer: √58 or about 7.6

Step-by-step explanation:

use the distance formula: ((x1 - x2)² + (y1 - y2)²)

((3 - 0)² + (7 - 0)²)

((3)² + (7)²)

(9 + 49)

The distance you travel while hiking is a function of how fast you hike and how long you hike at this rate. You usually maintain a speed of three miles per hour while hiking. Write a statement using function notation; let t represent the independent variable. Let h represent the function, and h(t) the dependent variable

Answers

h(t)=3t + k
Where k is a constant and h the distance covered and t the time taken

Answer: h(t)=3t

,where h(t) represents the distance we travel while hiking in time t which is the dependent variable.

Step-by-step explanation:

Given: The  distance we travel while hiking is a function of how fast we hike and how long we hike at this rate.

The maintained speed while hiking= 3 miles per hour

If t represent the time of hiking which is independent variable,  and h(t) represents the distance we travel while hiking which is dependent variable.

Then, h(t)=3t

you can do anyting to an equaiton as long as you do it to both sidess

distributive property
a(b+c)=ab+ac
commutativ property
a+b=b+a

distribute
3(4x-2)=12x-6

12x-6=9+2x+5
add 6 both sides
12x+6-6=9+6+5+2x

How can we tell if a number is divisible by 4? A. The last two digits of the number are divisible by 4   B. The sum of the digits is 4   C. The sum of the digits is divisible by 4   D. The last digit is divisible by 4

Answers

A, the last two digits of the number are divisible by 4
A is the correct answer. We all know that 100 is divisible by 4, so any multiple of 100 is also divisible by 4 (ex. 500, 1500, etc.)z Therefore, any number can be divisible by 4 regardless of what is in the hundreds place and above. What counts is the last two digits of the number, the tens and ones places. For example, let's look at 334 and 324. 34 is not divisible by 4, therefore 334 is not divisible by 4. 24 is divisible by 4, therefore 324 is divisible by 4. Check in a calculator for proof!
