Answer:
8(y + 27) ≤ -15
Step-by-step explanation:
In the given inequality statement, "Eight times the sum of a number and 27 is <u>at most</u> "-15""
The first part, "Eight times the sum of a number and 27" means that 8 is multiplied to the sum of y and 27. While the phrase "at most" means "<u>less than or equal to</u> (≤)" The phrase also implies that the value of y can be -15, or any value less than -15.
Therefore, the correct algebraic expression is: 8(y + 27) ≤ -15
Um I don't get it can you be more Pacific please
I think it's -$100
Answer:
-5√7 + 7√6
Step-by-step explanation:
5√7 + 12√6 - 10√7 - 5√6
Adding like terms:-
= -5√7 + 7√6 Answer.
Answer:
x = 25.35 (or 2129/84) and y = 4334.04 (or 121353/28)
Step-by-step explanation:
The given equations are set up and ready to go with substitution. Simply just plug in the first equation to the second equation as both are equal to y.
Step 1: Replace y in <em>y = 87x + 2129 </em>with <em>171x</em>
171x = 87x + 2129
Step 2: Subtract 87 x on both sides
84x = 2129
Step 3: Divide both sides by 84 to get x
x = 2129/84 or 25.35 (rounded)
To get y, simply plug in x into one of the 2 original equations. In this case, I will use the first equation:
y = 171 (25.35)
y = 121353/28 or 4334.04 (rounded)
You can check your work by plugging both solutions into the calculator and see if they equal each other. The values for these answers are solely based on the equations, so if you write the <em>equations </em>wrong themselves, then that means you have the values wrong as well.
