Answer:
</h2>
20 x + 500 y cents
<h2>
Step-by-step explanation:
</h2>
20 x cents already given in question
converting 5 y dollars into cents (1 dollar=100 cents, 5 dollars =500 cents)
5 y dollars =500 y cents
20 x cents+500 y cents
20 x + 500 y cents
Answer:
Step-by-step explanation:
I am going with A......12x + 7y....x = # of adult and y = # of children.....adults cost 12 and children cost 7 <====
B doesn't make much sense....u could say x was for girls and y for boys...but u already know how many there are....so I am not sure what the x and y could stand for.
C does't make much sense either....x would have to be red marbles and y would have to be green marbles...but just like B, u already know how many there are....so not sure what x and y could stand for
D. wrong....because the box containing x 7 oz packages and y 12 oz packages.....12x + 7y....for this one to be correct, it would have to have x 12 oz packages and y 7 oz packages
X+4-4=15.25-4
X=11.25
Answer would be 1. X=11.25
-3Ix + 7I = -12 (divide -3 from each side)
Ix + 7I = -12/3
Ix + 7I = -4
x + 7 = -4 or -x - 7 = -4
x = -11 or -x = 3
x = - 3
x = -3 or -11
Answer:
Step-by-step explanation:
In order to find which expression is equivalent to 
, we need to note the order of operations.
PEMDAS tells us that when solving an equation, we'd go in this order.
<em>P</em><em>arentheses</em>
<em>E</em><em>xponents</em>
<em>M</em><em>ultiplication/</em><em>D</em><em>ivision</em>
<em>A</em><em>ddition/</em><em>S</em><em>ubtraction</em>
Using this, we'd start by evaluating what's inside the parentheses, 
. We'd then bring that value to the 0th power.
<em>Wait...</em> there's something special about bringing anything to the 0th power. Bringing anything to the 0th power makes the value 1.
It can be -5... it can be 1,000,000, any number possible, taken to the 0th power, will always be 1.
So no matter what the value inside the parentheses is, taking it to the 0th power will <u>always make it 1</u>.
Therefore, this expression is equivalent to 1.
Hope this helped!
