Answer:
8/11
Step-by-step explanation:
2 2/3 = 8/3
8/3 x 3/11 = 24/33
24/33 = 8/11
Answer:
The two step equation that we can use to find michael's age is x = (f-2)/4 where f = 30. So Michael is 7 years old.
Step-by-step explanation:
In order to solve this problem we will attribute variables to the ages of Michael and his father. For his father age we will attribute a variable called "f" and for Michael's age we will attribute a variable called "x". The first information that the problem gives us is that Michael's dad is 30 years of age, so we have:
f = 30
Then the problem states that the age of the father is 2 years "more" than four "times" Michaels age. The "more" implies a sum and the "times" implies a product, so we have:
f = 2 + 4*x
We can now find Michael's age, for that we need to isolate the "x" variable. We have:
f - 2 = 4*x
4*x = f - 2
x = (f-2)/4
x = (30 - 2)/4 = 7 years
The two step equation that we can use to find michael's age is x = (f-2)/4 where f = 30. So Michael is 7 years old.
First I did 8*6 which is 48 ( meaning there is 48 slices total)
Then take 36 and subtract that from 48 getting 12.
So there is 12 slices of pizza left over.
2x+3y=5
-3x+2y=-14
3( 2x+3y=5)
2 (-3x+2y=-14)
--------------------
13y=-13 ⇒y=-13/13=-1
2( 2x+3y=5)
-3(-3x+2y=-14)
---------------------
13x = 52 ⇒x=52/13=4
Answer: x=4; y=-1
To check:
2x+3y=5
2*4+3*(-1)=8-3=5
-3x+2y=-14
-3*4+2*-1=-12-2=-14
