Answer:

Step-by-step explanation:

Realize what (-5)^3 means

(-5)(-5)(-5)

25(-5)

-125

meanwhile

(-9)^2 is

(-9)(-9)

81

Basically a negative times a negative is always positive, but when a negative number is cubed (or raised to any odd exponent for that matter) the product will be negative.

Two equations are given below:
goldenfox [79]
Since the second equation gives a value for a, we can substitute it into the other equation to find a value for B.

Let's substitute b-2 into the first equation wherever there is an a.

a - 3b = 4
(b-2) - 3b = 4
b - 2 - 3b = 4
-2 - 2b = 4
-2b = 6
b = -3

Now let's find a by substituting -3 into either of the equations to find the value of a.

a = b - 2
a = -3 - 2
a = -5

So your solution set  is (-5, -3)

Paul's Pizzeria sells 45 cheese pizzas and 20 pepperoni pizzas each week.
kaheart [24]
Okay so there are 45 cheese pizzas and 20 pepperoni pizzas
they are asking for the ratio of cheese pizzas to pepperoni pizzas
that would be 45:20
now this needs to be simplified, so divide both numbers by a common factor, which would be 5 in this case...45/5=9 and 20/5=4
so the ratio would be 9:4

A student is 5 feet, 2 inches tall. What is her height in meters?
Maurinko [17]
We know that 1 feet is 0.3m and that 1 inch = 0.0254 m
To get the result we have to multiply 5 feet by 0.3 and 2 inches by 0.0254 and add it.
5*0.3=1.5
2*0.0254=0.0508
Now adding
1.5+0.058=1.55m - its the answer
