Answer:

Option A is correct

Step-by-step explanation:

Given two equations

x-y=2....(1)

2x+3y =14...(2)

we have to solve the above equations using elimination method.

Multiplying (1) equation by 2, we get

2x-2y=4....(3)

Subtract equation (3) from (2), we get

3y-(-2y)=14-4

5y=10

Dividing by 5, we get

y=\frac{10}{5}=2

(1) implies x-y=2

x-2=2

x=2+2=4

hence, the solution is (4,2)

Option A is correct.

A square field has an area of 100 square meters. What is the length of the square? Show how you got the work please.
Goryan [66]

Answer:

The length of the square is 10 meters.

Step-by-step explanation:

First, you need to know that a square has four equal sides, and that finding the area of a square means multiplying one side by another side. This means that if you know the area of the square, all you have to do is find the square root of the area to find a side length. So, by using a calculator, you can find that the square root of 100 is 10, which is the length of one side of the square.

Paraphin [41]

Answer:

<h2>B. (2, 1)</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}-3y=x-5&\text{subtract x from both sides}\\x+5y=7\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}-x-3y=-5\\x+5y=7\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\qquad2y=2\qquad\text{divide both sides by 2}\\.\qquad\qquad y=1\\\\\text{Put the value of y to the second equation:}\\x+5(1)=7\\x+5=7\qquad\text{subtract 5 from both sides}\\x=2

Answer:

Hypotenuse or c = 75 in.

Step-by-step explanation:

The Pythagorean Theorem is as follows:

a^2 + b^2 = c^2 (We know the length of the legs, or a and b, so we can use the formula to find the length of c, or the hypotenuse)

c^2 = 21^2 + 72^2    (Simplify)

c^2 = 5625    (Take the square root of both sides)

c = 75 in.
