Answer:

15i

Step-by-step explanation:

(-2+i)(3-6i)

Use the FOIL method then combine the real and imaginary parts of the expression.

(-2+i)(3-6i)

-2 (-3-6i) + i (3-6i)

-2 * 3 - 2 (-6i) + i (3-6i)

-2 * 3 - 2 (-6i) + i * 3 + i (-6i)

-6 + 12i + 3i + 6

0 + 12i + 3i

12i + 3i

15i

VladimirAG [237]

Answer:

0.50b+1.25h=20

Step-by-step explanation:

Let b be the number of balloons and h be number of party hats.

We have been given that balloons cost $0.50 each, so cost of b balloons will be 0.50b.

We are also told that party hats each cost $1.25, so cost of h party hats will be 1.25h.

Further, Joe wants to spend exactly $20 on the party supplies. We can represent this information in an equation as:

0.50b+1.25h=20

Therefore, the equation 0.50b+1.25h=20 represents the number of balloons ( b) and the number of party hats ( h) that Joe can buy spending exactly $20.
