Answer: 32 year
Step-by-step explanation:
Let Jerrey age is 'y' year
Mell age = 2y
Now,
2y – 16 = y + 16
y = 32
∴ Mells age = 64 year
& Jerrey age = 32 year
line m can be represented by the equation 3x-6y=18. Write an equation of the line perpendicular to line m that passes through the point (-4,1)
Step-by-step explanation:
the perpendicular line can be represented by bx-ay+k=0 ,So the second step Is Written
since the line passes through point (-4,1) ,the value of x and y is Substitute as written in answer
Answer:
y=-2x-7
Step-by-step explanation:
3x-6y=18 also equals 3x-18=6y
divide both sides by 3 to get x-6=2y or y=x/2-3 as same line then, to find inverse switch x and y, x=(y/2)=3 and solve for y, y-6=2x, -y=2x+6 is the inverse then to make it pass thru (-4,1) change b value, y=-2x-7

Suppose that you decide to buy a car for $27,635, including taxes and license fees. you saved $5000 for a down payment and can get a three-year car loan at 6.36%. Find the monthly payment and the total interest for the loan
the monthly payment of $ 668.75 will be paid for the loan for the car.
Total payment for the car = $ 27,635
Money for down payment = $ 5000
Interest for 3 year loan = 6.36 %
Amount on which this interest will be applied = $ 27,635 - $ 5000
Amount = $ 22,635
Interest = 6.36 % of $ 22,635
Interest = 6.36 / 100 × $ 22,635
Interest = 1440 (approx.)
Total amount of loan = $ 22,635 + $ 1440
= $ 24075
Number of months = 3 × 12 = 36 months
So, monthly payment = $ 24075 / 36
= $ 668.75
Therefore, we get that, the monthly payment of $ 668.75 will be paid for the loan for the car.

Using a system of equations, the number of people on each tour is given as follows:
First tour: 12 adults and 7 children.Second tour: 14 adults and 5 children.Third tour: 8 adults, 11 children.What is a system of equations?A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the context of the given problem.
For this problem, the variables are described as follows:
Variable x: number of adults in the tour.Variable y: number of children in the tour.All the tours were fully booked, hence the following equation is used in all cases:
x + y = 19.
Four the first tour, considering the values of the ticket and the total receipts, the following equation is built:

which rational is qvuivalent to 0.86
The rational equivalent to 0.86 can be written as 43/50.
A rational number may be defined as the number which can be expressed in the form of p/q where p and q are integers, and the term q cannot be equal to zero. It can be either positive or negative or both. We can also say that any fraction which does not have zero in the denominator is called a rational number. Zero can also be regarded as a rational number as it can also be represented as a fraction. For example, 0/2, 0/5. In order to write 0.86 as a rational number, we have to convert it in fraction form. In fraction form it can be written as
0.86 = 86/100
This is also a rational number, but we simplify it further and we get

A construction crew is lengthening a road. The road started with a length of 53 miles, and the crew is adding 4 miles to the road each day.
Let L represent the total length of the road (in miles), and let D represent the number of days the crew has worked.
Write an equation relating L to D. Then use this equation to find the total length of the road after the crew has worked 36 days.
Answer:
L = 4D + 53
After 36 days of work, the road will be 197 miles long.
Step-by-step explanation:
This question requests that an equation is found to represent the relationship between the length of a road and the days that the workers spend working on the road.
We are given that the road is 53 miles long prior to the work done by the construction crew. This means that this will be added in addition to what we will find.
L represents the length of the road after D days. Since the road is lengthened by 4 miles each day, this could be represented by 4 * D, or simply 4D.
Therefore, the equation we find can be written as L = 4D + 53.
Since we need to find how many miles the road will be after 36 days of work, substitute 36 days as D and solve for L:
L = 4(36) + 53
L = 144 + 53
L = 197
Therefore, the road will be 197 miles long after 36 days of construction.

What is Parallel line ?
Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.
Given that a line's equation is,
y = 8 / 9x - 7
If we contrast this equation with a line's slope-intercept,
this line's slope = 8/9
Since every line parallel to this one will have a same slope,
The parallel line's slope is equal to
The symbol for the line with the slope 'm' and the coordinates (x', y') is
y - y' = m(x - x')
As a result, the equation of the line through (-1, 8) with a slope will be,
y - 8 = 8/9 (x-1)
y =8/9x - 8/9 - 8
y = 8/9x + 64 / 9

From the given linear equation graph, we can tell that the equation of the line in slope intercept form is; y = 1.2x + 3
How to Interpret Linear Equation Graph?
The general form of equation of a line in slope intercept form is;
y = mx + c
where;
m is slope
c is y-intercept
From the given graph, we see that;
y - intercept = 3
x - intercept = -2.5
Now, we can find the slope by taking two coordinates;
(-2.5, 0) and (0, 3)
Slope = (3 - 0)/(0 - (-2.5))
Slope = 3/2.5
Slope = 1.2

Inequalities that use < or > symbols are always plotted with a dashed line while Inequalities that use ≤ or ≥ symbols are always plotted with a solid line.
Now, if the shaded portion is above a dashed line, the the symbol is > but if it is shaded above a solid line, then the symbol is ≥. In this question, a solid line is used for both equations and shaded above the lines and so we will use ≥.

most the jeans can cost?
A) $46.49
B) $46.72
C) $29.41
D) $45.16
Answer:
B) $46.72
Step-by-step explanation:
Let j = cost of the jeans
j * 1.07 is the cost of the jeans with tax
j * 1.07 = 49.99
Divide each side by 1.07
j * 1.07 /1.07 = 49.99 / 1.07
j =46.72
The jeans can cost no more than 46.72
Answer:
B) $46.72
Step-by-step explanation:
The problem can be expressed as an equation you solve for "y"
y + y * 0.07 = 49.99
We factor out the "y" from the equation and we get
y * (1 + 0.07) = 49.99
Which is the same as
y * 1.07 = 49.99
We can then divide by 1.07 both sides
y = 49.99 / 1.07
Which yields
y = 46.719

Solve for x -

Answer:
x = 15
Step-by-step explanation:
Let's start by copying down the equation.
6 + 4x + 3 = 6x - 21
Let's simplify this equation and we get,
4x + 9 = 6x - 21
Now, we can add 21 to both sides to isolate 6x on one side. Then, we get...
4x + 30 = 6x
Now, we minus 4x from both sides to get rid of it.
Then we get...
2x = 30
Thus, x = 15
6 + 4x + 3 = 6x - 21
We minus (4x+3) on both side.
6 + 4x + 3 - (4x+3) = 6x - 21 - (4x + 3)
6 = 2x - 24
2x = 30
x = 15.

10 oranges and 20 grapefruits weigh 35 pounds total. 16 oranges and 10grapefruits weigh 23 pounds total. How much would 13 oranges and 15grapefruits weigh?A 28 poundsB 29 poundsC 30 poundsD 58 pounds20 Illuminate Education, Inc.
First, we will find the weight of each oranges and grape fruit
Let x be the unit weight of orange
Let y be the unit weight of grape fruit
If "10 oranges and 20 grapefruits weigh 35 pounds total"
Then this implies;
10x + 20 y = 35 -----------------(1)
And
If " 16 oranges and 10 grapefruits weigh 23 pounds total"
This implies;
16x + 10y = 23 ---------------------(2)
We can solve the two equations simultaneously.
Using elimination method;
we eliminate y and to do that, the y variables in the two equations must be same, Hence we can achieve that by multiply equation (1) by 10 and then multiply equation (2) by 20
100x + 200y = 350 ----------------------------(3)
320x + 200y = 460 ------------------------------(4)
subtract equation (3) from equation (4)
220x = 110
divide both-side of the equation by 220
x = 0.5
substitute x=0.5 into equation(1) and then solve for y
10(0.5) + 20y = 35
5 + 20y = 35
subtract 20 from both-side of the equation
20y = 35 - 5
20y = 30
divide both-side of the equation by 20
y = 1.5
"13 oranges and 15 grape fruits" = 13 x + 15y
substituting x = 0.5 and y= 1.5 in the above;
13(0.5) + 15(1.5)
=6.5 + 22.5
=29
Hence;
13 oranges and 15 grapefruits will weigh 29 pounds
