Answer: 6 = t
Step-by-step explanation: To get <em>t</em> by itself since -3 is being multiplied by <em>t</em>, divide both sides of the equation by -3.
On the left, -18 divided by -3 is 6 and on the right, the -3's cancel.
So <em>6 = t</em>.
Answer:
Option D is correct.
Step-by-step explanation:
Let V be the volume of hay in each stack
Given:
Length of the each stack is 
And Jay stores hay in cubic stacks on his farm.
The volume of the cone is.
Now, we substitute value of length of stack in above equation.
Therefore, the volume of hay in each stack is
1.25kg = 2.75577828 pounds
Do 5*12 because that's 5*(4+4+4) which the 4s are the base lengths added together. So you have 60 for one part of the figure.
Next, you have 2*4 left to add on to the figure which is 8.
So 60+8=68 is your answer
68 units^2
Hope this helped!
I'll go over part A.
What's happening is that we are plugging some unknown number x into the function, and getting -1 as the result. The function rule is 3*x-7 which translates to "multiply the input number by 3, then subtract off 7"
Notice how multiplication comes first and then we subtract. This is following the order of operations PEMDAS (some books may call it BEDMAS depending on your region). The M for multiplication comes before the S for subtraction.
To isolate x, we follow the order of operations in reverse. We undo the "subtract off 7" then we undo the "multiply by 3"
So this is how it all works out
f(x) = 3x-7
-1 = 3x-7 .... replace f(x) with -1
3x-7 = -1
3x-7+7 = -1+7 ... add 7 to both sides to undo the "-7"
3x = 6
3x/3 = 6/3 ... divide both sides by 3 to undo the "multiplication"
x = 2
Therefore, if the input is 2, then output is -1
------------------------------------------------------------
Let's plug x = 2 into the function and see what happens
f(x) = 3x-7
f(2) = 3*2-7 .... replace x with 2
f(2) = 6-7 .... multiply
f(2) = -1 .... subtract
The input x = 2 leads to the output -1
So this confirms that x = 2 is the proper answer for part A
