Imani and Chelsea are selling cookie dough for a school fundraiser. Customers can buy packages of sugar cookie dough and packages of oatmeal cookie dough. Imani sold 1 package of sugar cookie dough and 2 packages of oatmeal cookie dough for a total of $31. Chelsea sold 1 package of sugar cookie dough and 10 packages of oatmeal cookie dough for a total of $135. Find the cost of one package of sugar cookie dough and one package of oatmeal cookie dough.

The cost of one package of sugar cookie dough and one package of oatmeal cookie dough is $5 and $13 respectively

Step-by-step explanation:

Let us assume the cost of one package of sugar cookie dough be x

And for one package of oatmeal cookie dough be y

Now the equations are

x + 2y = $31

x + 10y = $135

Solve these two equations by adding minus sign

-8y = -$104

y = $13

And, for x

x + 2($13) = $31

x = $31 - $26

= $5

Hence, the the cost of one package of sugar cookie dough and one package of oatmeal cookie dough is $5 and $13 respectively

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

pi x^2

step-by-step explanation:

pi times x squared
