A system of two linear equations with two variables is
shown below.
2x + y = 7
3x - 4y = 5
Which answer is the solution to the system of linear
equations?
Answer:
:/
Step-by-step explanation:
Answer:
x = 3, y = 1
Step-by-step explanation:
Given the 2 equations
2x + y = 7 → (1)
3x - 4y = 5 → (2)
Multiplying (1) by 4 and adding to (2) will eliminate the y- term
8x + 4y = 28 → (3)
Add (2) and (3) term by term to eliminate y
11x = 33 ( divide both sides by 11 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
2(3) + y = 7
6 + y = 7 ( subtract 6 from both sides )
y = 1
solution is x = 3 and y = 1
Write each sentence as an equation. Eight less than 1/3 a number is n -13.
Answer:
Step-by-step explanation: Given that eight less than one-third of a number n is -13.
We are to find the value of n.
According to the given information, the equation for n can be written and solved as follows :
Thus, the required value of n is -15. I hope this really helps you(:
Answer:
[tex]\bold{\frac{n}{3} - 8 = - 13}[/tex]
and the solution is
[tex]\bold{n = -15}[/tex]
Step-by-step explanation:
I believe this sentence is mistyped
It should be Eight less than 1/3 a number n is -13
Analyze the word problem piece by piece not necessarily from the beginning of the sentence
The number is given as n in the sentence part boldfaced belowIf you wanted to solve this equation for n here's how to proceed
Add 8 to both sides to isolate the n termPlease help me!!

On average, Cody runs 4 miles in 38 minutes. How fast should he plan to run a 10-mile race if he maintains this pace?
A.1 hour 3 minutes
B.1 hour 16 minutes
C.1 hour 35 minutes
D.2 hours 30 minutes
Answer:
It will take him 1 hour 35 minutes to finish a 10 mile race
Answer is (C)
Cody runs 10-mile in 1 hour 35 minutes.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
Cody runs 4 miles in 38 minutes.
Now,
Since, Cody runs 4 miles in 38 minutes.
Hence, The time to run 10 miles = 38 × 10 / 4
= 380/4
= 95 minutes
= 1 hour 35 minutes
Thus, Cody runs 10-mile in 1 hour 35 minutes.

Each of the domain values, x, should only output a single unique range value, y.
This example is a relation and not a function because the the domain value of -1 output 2 distinct range values.

a norman window has the shape of a rectangle surmounted by a semicircle. if the perimeter of the window is 25 feet, express the area of the window as a function of the width (across the base) of the window.
The area of the window is [tex]\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}[/tex]
The shape of the Norman window is described as a rectangle surmounted by a semicircle.
Let 'x' be the width of the window.
Then this width corresponds to the diameter of the semicircle.
That is, radius of the semicircle = x/2
Now given the perimeter of the whole window = 25 ft
This perimeter is equal to the sum of 3 sides of the rectangle and the perimeter of the semicircle.
Perimeter of the semicircle = [tex]\frac{2\pi r}{2} = \frac{\pi x}{2}[/tex] , where r is the radius of the semicircle.
Now let 'y' be the length of the window.
Then sum of three sides of the window = 2y + x
So 2y + x + [tex]\frac{\pi x}{2}[/tex] = 25
Therefore, [tex]y =( 25 - x - \frac{\pi x}{2} ) / 2[/tex]
Area of the window = Area of the semicircle + Area of the rectangle =
[tex]\frac{\pi x^2}{8} +xy = \frac{\pi x^2}{8} + x( 25 - x - \frac{\pi x}{2} ) / 2\\ = \frac{\pi x^2}{8} + (25x - x^2 - \frac{\pi x^2}{2} ) / 2[/tex]
So Area of the window = [tex]\frac{25x}{2} -(1 +\frac{\pi}{2} )\frac{x^2}{2}[/tex]
