Answer:

7=x/5; she has earned 35 points

Step-by-step explanation:

(5)7=x/5(5)

so, you multiply each side by five, since the inverse operation of division is multiplication, then solve.

7(5)=35

x/5(5)=x

so x (the number of points she earned) is equal to 35.

Multiply the polynomials: (x + 3)(x2 – 5x + 12)
LekaFEV [45]

Answer:

x³ - 2x² - 3x + 36

Step-by-step explanation:

(x + 3)(x² - 5x + 12)

Each term in the second factor is multiplied by each term in the first factor , that is

x(x² - 5x + 12) + 3(x² - 5x + 12) ← distribute parenthesis

= x³ - 5x² + 12x + 3x² - 15x + 36 ← collect like terms

= x³ - 2x² - 3x + 36

Autumn has $0.64 worth of pennies and nickels. She has a total of 20 pennies and nickels altogether. Determine the number of pen
kkurt [141]

Answer:

Correct answer: Nickels x = 11 and pennies y = 9

Step-by-step explanation:

We will first define the variables in the system:

Let be nickels x and pennies y

We will form a system to solve this problem:

5 x + 1 y = 64

x + y = 20/ · (-1)

we will first multiply the second equation by -1 and add it by the first and get:

4 x = 44 ⇒ x = 44 / 4 = 11 nickels

x = 11 nickels

from the other we get y

y = 20 - x = 20 - 11 = 9 pennies

y = 9 pennies

God is with you!!!
