4 consecutive numbers that add up to 578

Step-by-step explanation:

You would need to form an equation to solve this

The equation would be: x + (x+1) + (x+2) + (x+3) = 578

Now you need to simplify it: 4x+6= 578

Bring the constants to one side: 4x = 572

Divide 4 on both sides: 4x/4 = 572/4

Simplify: x = 143

x = 143

x +1 = 143 +1 = 144

x + 2 = 143 + 2 = 145

x + 3 = 143 + 3 = 146

Checking the answer...

143 + 144 + 145 + 146 = 287 + 291 = 578

Hope this helps!!!

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
