1) its number 2. 30x^7y^4
It is 74 degrees because those two equations equal each other and you must cancel them out which equals x=15. plug 15 in to one of the equations and you have the answer.
Answer:
21, 22, 23
Step-by-step explanation:
Construct equations representing each piece of information.
Three consecutive integers are three numbers in a row, for example, 1, 2 and 3.
Let's let
Integer 1 = X
Integer 2 = Y
Integer 3 = Z
X = (Y + Z) - 24
We also know that
Y = X + 1
and Z = X + 2
We can now sub this information into the first equation. We do this so that we can have only one variable in the equation.
X = (X+1) + (X+2) - 24
now solve for x,
X = 2X + 3 - 24
X = 2X - 21
-X = - 21
X = 21
So, the integers are 21, 22, 23
