Addition:
The act of combining two or more items is known as addition. The process of computing the sum of two or more numbers in mathematics is called addition. It is a fundamental mathematical procedure that is frequently used in daily life. When we work with money, figure out our food bills, or figure out the time, we frequently employ addition. One-digit numbers can be added simply for solving addition problems, however for bigger numbers, we divide the numbers into columns using their corresponding place values, such as ones, tens, hundreds, thousands, and so on.

A 13 km stretch of road needs repairs. Workers can repair 3 1/2km of road per week.
How many weeks will it take to repair this stretch of road?
The workers would need 3.71 weeks to repair the road.
A generalization of arithmetic in which letters representing numbers are combined using arithmetic rules
Given that the total length of the road is 13km. Workers can repair 3.50 roads per week.
To determine the number of weeks required to repair the road, divide the total by per week. The equation would be:
13 ÷ 3.5
= (13 x 10)/35
= 130/ 35
= 3.71

The following are three equivalent expressions for the submarine's final position -(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)
What is defined as the equivalent expressions?
Expressions that function identically despite having distinct appearances are called equivalent expressions. If two algebraic expressions are equivalent, then when we enter the same value(s) for the variable, the two expressions have the same value.Each float advances by 5 units.
Each group takes a two-unit step.
As a result, the submarine's final position is:
Final = -(5)(3) - (2)(4)
The minus "-" symbol indicates that the submarine is sinking.
Thus, the following are equivalent expressions for the submarine's final position:
-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)

I don't know whether this line is a negative or positive. The line is crossing the origin and is in the 1 quadrant and 3 quadrant. Please help!!
The given line is positive.
What is slope ?
A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).
Given that,
The line is crossing the origin and is in the 1 quadrant and 3 quadrant.
This means, the graph of the line starts at the bottom left and goes towards the top right.
If a line has a positive slope, then y always rises when x rises and always falls when x falls (i.e., m > 0). The line's graph thus begins at the bottom left and moves up to the top right.
So, the given line is positive.

Write the equation of the line in fully simplified slope-intercept form.
The equation of the straight line in slope-intercept form is given by
y = -x +6 .
The line of the graph is clearly passing through the points (5,1) and (3,3) .
Hence the slope of the line = (3 - 1) / (3 - 5) = 2 / (-2) = -1
The equation of the straight line will be given by the formula:
y-3 = -1 (x-3)
or, y - 3 = -x +3
or, y + x = 6
One of the most popular ways to display a line's equation is in the slope intercept form, which looks like a straight line.
When the slope of anything like the straight line and in fact the y-intercept are known, the slope intercept formula can be used to determine the equation of a line the y-coordinate of the point where the line crosses the y-axis. A line cannot exist unless every point on the line fulfils an equation.
Hence the equation of the line in slope intercept form is y = -x +6

Consider the diagram shown. what is the angle of x
By using angles properties (sum of interior angles of a triangle and so) we will see that the measure of angle x is 120°.
How to get the value of angle x?Let's define C as the angle inside the triangle that is adjacent to angle x.
We can see that these two are supplementary angles, then we know that:
C + x = 180°.
We also can see that C is an interior angle of a triangle, and remember that the sum of all interior angles of a triangle is equal to 180°, then we can write
68° + 52° + C = 180°
With that equation, we can find the value of C.
C = 180° - 52° - 68° = 60°
Then.
x + C = 180°
x + 60° = 180°
x = 180° - 60° = 120°
That is the measure of angle x.

Step-by-step explanation:
An irrigation system (sprinkler) has a parabolic pattern. The height, in feet, of the spray of water is given by the equation h(x)=−x2+10x+9.5, where x is the number of feet away from the sprinkler head (along the ground) the spray is.
The irrigation system is positioned 9.5 feet
The spray reaches a maximum height of 34.5 feet
The spray reaches all the way to the ground at about 10.87 feet
How to find the maximum height of the spray
The standard form of a quadratic equation is given by the formula
y = ax^2 + bx + c
compared with the given equation h(x) = −x^2 + 10x + 9.5 the solutions are calculated as follows
The irrigation position refers to the value of h(x) at x = 0
h(x) = −x^2 + 10x + 9.5
h(0) = 0^2 + 10*0 + 9.5
= 9.5
The maximum height is at the symmetry of the parabolic curve, for a curve opening downward.
At the symmetry x = -b/2a
x = -b/2a = -10/(2 * -1) = 5, At x = 5, then y is
h(5) = −(5)^2 + 10 * 5 + 9.5 = 34.5
The maximum horizontal distance is at one of the roots solved as
h(x) = −x^2 + 10x + 9.5
x = 10.87 OR -0.87
The maximum distance is the greatest distance form the origin (0, 0). Therefore maximum distance is at x = 10.87 feet
