The school is having a bake sale and the math club is bringing cupcakes. they have 180 total cupcakes, both chocolate and strawberry. the number of chocolate cupcakes is eighteen more than twice the number of strawberry cupcakes. which system of equations can be used to find the number of chocolate cupcakes, c, and the number of strawberry cupcakes, s? a. c + s = 180 s = 2c - 18 b. c + s = 180 c = 2s + 18 c. c - s = 180 s = 2c + 18 d. c = 2s c - 180 = s

The volume of a cube is 8 in to the 3rd power. how long is each side?

Ihave trouble finding the nth term of a linear sequence

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
