A non zero real number could be written as a/1.
When this gets reversed to be 1/a, it is the multiplicative inverse.
Answer:
none
Explanation:
Fill in each option for x individually.
I) 9
-10 - 4(-1)
II) 9
-10 - 4(-3)
III) 9
-10 - 4(-2)
Then, simplify the right side of each inequality.
I) 9
-6
II) 9
2
III) 9
-2
Each of these inequalities are flase. 9 is not less than or equal to any of these values, so the answer is none.
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.
The formula you need to use is C = 5/9•(F - 32)
So take 15 and subtract 32: 15-32 = -17
Then multiply that by 5/9: 5/9•(-17) ≈ -9.44
Answer:
= 384
Step-by-step explanation:
(-8)(-4)(12)
= (32)(12)
=384
