5x - 7y =58

y =-x +2


Using the substitution method, replace y in the first equation with the second equation:

5x - 7(-x+2) = 58

Simplify by using the distribution property:

5x - (-7x) - 14 = 58

Simplify by combining like terms:

12x -14 = 58

Add 14 from each side of the equation:

12x = 72

Divide both sides by 12:

X = 72/12

x = 6


Now you have x, replace x in the second equation and solve for y:

y = -x +2

y = -6 +2

y = -4


X = 6, y = -4

What equation does the model represent?

It would be 62+23=94 because you'll need to add the tens and the ones, then add it up

I think-_-

When any shape is inscribed in a circle, it means that the shape is within the circle but all of the corners are touching the circle. So this could just look like a square within a circle with the corners of the square touching the circle but not going outside of the borders of the circle. Repeat this process with the other shapes. The central angle used to locate the vertices is found by taking the number of sides on the shape and divide it by 360 (the angle of a circle). So for a square with 4 sides, you would take 360/4 and get 90 degrees. This means that each angle within the square is 90 degrees. That 90 degrees is the interior angle of the polygon (for a square specifically). Then what you do is look at the circle and draw a dot at the center of it. You can use a protractor for this part if you want but you would find the central angle by picking a point on the circle and drawing a line to the center dot, then you rotate however many degrees you found in the interior angle of the polygon and you would draw a new line from the center of the circle to that point. You will continue this process until you have gone back to your starting point on the circle. The amount of times it takes you to repeat the process should be the amount of sides the polygon has that you are trying. Interior angle and central angle should be the same for the individual shapes but it would be different for different shapes like a square and an octagon because there are a different amount of sides.

Identify the property shown. −1.4+(−2.6+3.8)=(−1.4+(−2.6))+3.8
Dimas [21]
<span>This property is called associativity. It shows that it doesn't matter whether you perform the sum on the first two numbers and then the third, or on the second two and then the first, because you will get the same answer either way. That is because addition is associative.</span>
