Sonya's employer matches 25% of sonya's contributions to her 401(k) plan. if sonya's employer contributed $600 to the plan last year, how much did sonya contribute to the plan last year?

Sonya contributed $2,400 to the plan last year.

Step-by-step explanation:

Sonya's employer matches 25% of Sonya's contribution to her 401(k) plan.

Sonya's employer contributed $600 to the plan last year.

Let Sonya's contribution to her 401(k) plan be = x

employer's contribution  is 25% of x = 600

0.25x = 600

x = 600 ÷ 0.25 = $2,400

Therefore, Sonya contributed $2,400 to the plan last year.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.

the equivalent expression are always the hardest ones but you look at the gcf also
