Step-by-step explanation:
James and Eron are going on a road trip. Eron drove the first 180 miles of their trip. James drove the next 150 miles of their trip. They decided to drive the same amount of hours each for the rest of the trip. Eron drove at a speed of 60 miles per hour when he drove. James drove at a speed of 55 miles per hour when he drove.Let h represent the number of hours driven by each person.
Question seems incomplete but some explanation could help
Answer and explanation:
Distance travelled = speed × time
We know the speed for each driver:
Eron drove at 60 miles per hour
James drove at 55 miles per hour
We know they both drove same amount of time = h
Therefore Eron's distance travelled = 60 miles per hour × h = 60h
Jame's distance travelled = 55 miles per hour × h =55h
Total distance travelled for the rest of the trip = 60h + 55h

y=-x-4
Graph each equation then find a solution show your process.
Answer:
(x,y) = (-5,1)
Step-by-step explanation:
USES SUBSTITUTION METHOD
Solving Steps:
x + 6 = -x -4 (Solve the equation)
x = -5 (Substitute the value of x)
y = -(-5) - 4 (Solve the equation)
y = 1 (Substitute the value of y)
Answer: (x,y) = (-5,1)

Step-by-step explanation:
The average age of staff in the maths department is 40.
There are 7 members of staff (Jill, Nicky, Wendy, Cathy, Cerian, Alan and Andy).
The average age of Jill, Nicky and Wendy is 41.
The average age of Andy, Alan and Cathy is 43.
How old is Cerian?
Answer:
Cerian is 28 years old
Step-by-step explanation:
The given parameters are;
The average age of the staffs in the mathematics department = 40
The number of staffs in the department = 7
The average age of Jill, Nicky and Wendy = 41
The average age of Andy, Alan and Cathy = 43
From the given parameters, we have;
The average age of the staffs in the mathematics department = (The sum total of the ages of the members of the math department)/(The number of staffs in the department)
Therefore;
40 = (The sum total of the ages of the members of the math department)/ (7)
From which we have;
The sum total of the ages of the members of the math department = 40 × 7 = 280
Which gives;
Jill's age + Nicky's age + Wendy's age + Cathy's age + Cerian's age + Alan's age + Andy's age = 280 years
The average age of Jill, Nicky and Wendy = 41
Given that Jill, Nicky, and Wendy make up 3 of the 7 members of staffs, we have;
The average age of Jill, Nicky and Wendy = (The sum total of the ages of Jill, Nicky, and Wendy)/(The number of staff Jill, Nicky, and Wendt make)
Therefore;
The sum total of the ages of Jill, Nicky, and Wendy = 41 × 3 = 123
Which gives;
Jill's age + Nicky's age + Wendy's age = 123 years
Similarly, the sum total of the ages of Andy, Alan, and Cathy = 43 × 3 = 129
Which gives;
Andy's age + Alan's age + Cathy's age = 129 years
Therefore;
Cerian's age = (Jill's age + Nicky's age + Wendy's age + Cathy's age + Cerian's age + Alan's age + Andy's age) - (Jill's age + Nicky's age + Wendy's age) + (Andy's age + Alan's age + Cathy's age)
∴ Cerian's age = 280 years - 123 years - 129 years = 28 years

Martin earn the following scores on his last five test. What is the interquartile of his course
Answer:
18
Step-by-step explanation:
The interquartile range is the middle 50% of the data.
To find the interquartile range, we must first find the lower and upper quartiles.
In this case, the lower quartile is 76.5, and the upper quartile is 94.5.
Subtracting 76.5 from 94.5 gives us the answer of 18.

how to get 3.15 ratio
Answer:
Step 1) Convert the 3.15 percent to a decimal number.
To convert 3.15 percent to a decimal number, you divide 3.15 by 100. In other words, the quotient you get when you divide 3.15% by 100 is the decimal number.
3.15 ÷ 100 = 0.0315
Step 2) Convert the decimal number to a fraction.
To convert the decimal number to a fraction, we make the decimal number the numerator, and 1 the denominator.
0.0315 =
0.0315
1
Step 3) Remove the decimal point in the numerator.
To remove the decimal point in the numerator, multiply both the numerator and denominator by 10000.
0.0315 × 10000
1 × 10000
=
315
10000
Step 4) Simplify the fraction.
The greatest common factor of 315 and 10000 is 5. Therefore, to simplify the fraction, divide the numerator and denominator by 5.
315 ÷ 5
10000 ÷ 5
=
63
2000
Step 5) Convert the fraction to a ratio.
To convert the fraction to a ratio, replace the fraction divider line with a colon.
63
2000
= 63:2000
That was the final step. Below is the answer to 3.15 percent as a ratio.
3.15% = 63:2000

Solving quadratic equations - factoring.
Factor to solve each problem 1-3
Answer:
1) 1 1/2 ft.
2) 12 m.
3) 6 ft.
Step-by-step explanation:
1, 2) If the area is the same, then the sides are exactly half that of the surrounding square.
3) 9^2 = 81 ft^2 (or sqrt(81) = 9), if we take this 9 and subtract the 3 ft from it we will get the original side lengths.

Write an equation in slope-intercept form for the line with slope 1/5
and y-intercept 5.
Answer:
y=1/5x+5
Step-by-step explanation:
Slope-intercept form is written y=mx+b.
y- needs to be by itself in this form.
m- the slope.
x- always to the right side of the slope, or m.
b- y-intercept.
Now that we know this, all we have to do is plug in the numbers we have. So when we plug this in, the equation looks like this:
y=1/5x+5

Let us represent:
Cost Adult tickets = x
Cost Children's tickets = y
The total cost of ticket = C =
A family goes to an amusement park adult tickets cost $21 children under 10 years of age pay $15
C = $21 × x + $15 × y
C = 21x + 15y
The total cost of 4 adult tickets and 3 children's tickets is calculated as:
C = 21 × 4 + 15 × 3
C = 84 + 45
C = $129
