Your problem is giving you d in terms of t, meaning that it is asking if we replace t with 11, what would d be?
When a number is right in front of a variable, they are being multiplied
So if t is 11, and the problem shows 11t, we replace the t with 11 and put parentheses around it
d = -20 + 11t
d = -20 + 11(11)
d = -20 + 121
d = 101
And there you have it! Your final answer is d = 101!
Practice pre-algebra and plugging in numbers into equations! Having mastery over the basic math functions and rules, as well as Order Of Operations, makes all of this so much easier!
I recommend that you watch Khan Academy videos and practice problems on there! It is a great resource! What you are learning would most likely fall under pre-algebra!
Answer:
Step-by-step explanation:
Looking at our particular problem...let's identify everything that's going on here. What's inside the box are the coefficients from the original polynomial, with the last number being the constant. If we have 3 numbers there, which we do, then the first number is a coefficient on x², the second number is the coefficient on x, and the third number is the constant. So from that we know that our original polynomial was a 2nd degree, namely:
3x² + 7x - 20
The number outside the box is the number we are dividing into this original polynomial. This is a number in solution form. That means that x = -4. If
x = -4 is a solution, then the factor is (x + 4) = 0.
The numbers in the very bottom row are the coefficients of what is called the depressed polynomial, and this depressed polynomial is one degree less than the degree with which we started. So this depressed polynomial is a linear one (first degree, which is a line). The very last number in this bottom row is the remainder. If the remainder is 0, then -4 is a solution of the polynomial, it is also a 0, and (x + 4) is a factor of the polynomial. Our remainder is a 0.
So putting that all together gives us the answers as A, C, and E are our choices.
3 and 7/10 or 37/10
Just look up mixed numbers
You must convert it into a fraction so it will be a mixed number
.7 is 7/10 of 1
