5x−3−7x = 15−x What is x?
Schach [20]
Simplify 5x-3-7 to -2x-3
-2x-3=15-x
Add 2x on both sides
−3=15−x+2x
Simplify 15-x+2x to 15+x
−3=15+x
Subtract 15 on both sides
-3-15=x
Simplify -3-15 to -18
-18=x
X=-18

What is the value of x in the equation x+x+2 divided by 4 equals 189.5
AlekseyPX
Answer: x = 94.5

Explanation: By using PEMDAS you can see there is no parentheses, exponents, or multiplication, so you start with dividing.
You can go ahead and combine the two x’s so you have 2x. So our equation now looks like:
2x + 2 ÷ 4 = 189
Divide first.
2 ÷ 4 = .5
Subtract from both sides.
.5 - 189.5 = 189
Divide by two to isolate the variable.
2x ÷ 189 = 94.5
so X =94.5
check your answer by plugging in the final number.
94.5 + 94.5 + 2 ÷ 4 = 189.5

The diagonals of a quadrilaretral intersect at (-1,4). One of the sides of the quadrilateral is bounded by (2,7) and (-3,5)
Maurinko [17]

Solution:

Properties of Square

1. All sides are equal.

2. Opposite sides are parallel.

3. Diagonals are equal and bisect each other at right angles.

As, given point of intersection of diagonals of square is (-1,4).

And, One of the sides of the quadrilateral is bounded by (2,7) and (-3,5).  

Drawn the picture of square below,

Let, the third and fourth vertices of square be (x,y) and (p,q).

As, diagonals of square bisect each other. So,

\frac{x+2}{2}=-1\\\\ x +2=-2\\\\ x=-2-2\\\\ x=-4\\\\ \frac{y+7}{2}=4\\\\ y+7=8\\\\ y=8-7\\\\ y=1\\\\ \frac{p-3}{2}=-1\\\\ p-3=-2\\\\ p=3-2\\\\ p=1 \\\\ \frac{q+5}{2}=4\\\\ q+5=8\\\\ q=8-5\\\\ q=3

So, third and fourth vertices are (-4,1) and (1,3).
