Answer:
a = -10
Step-by-step explanation:
33 - 4a = 73
To get <em>a</em> by itself, you must move 33 to the other side. To this, you must subtract it from both sides, canceling it out on the left side.
You will be left with: -4a = 73-33
Subtract 73 and 33, which will get you 40.
Now the equation is -4a = 40
To get <em>a </em>by itself, divide -4 into both sides. Doing this will isolate <em>a</em>.
The equation you will have after that is a = 40/-4.
Divide 40 by -4, which will get you -10.
Therefore, a = -10.
Answer:
6241 is one answer , but see below.
Step-by-step explanation:
If the number is vwxy we have:
v = 3w
x + y = v - 1
w = x - 2
From equations 1 and 2:
v = 3(x - 2).
The only possible values of v are 3, 6 or 9.
If v = 3:- 3 = 3(3 - 2) so x = 3 also.
If v = 6:- 6 = 3(4 - 2) so x = 4.
If v = 9:- 9 = 3(5 - 2) so x = 5.
Now consider the first equation x + y = v - 1:-
If v = 3 then 3 + y = 3 - 1 giving y = -1 so v = 3 is not possible.
If v = 6 then 4 + y = 6 - 1 giving y = 1 which is a possible value.
If v = 9 then 5 + y = 9 - 1 giving y = 3 which is also possible.
If x = 4 w = 4 - 2 = 2
If x = 5 w = 5-2 = 3.
Thus the possible values are 6241 or 9353.
If all digits must be different the answer is 6241.
This is a TRUE statement. Consider the following example:
5 can also be written as
. Any variable raised to power 0 is equal to 1. So x raised to power 0 is equivalent to multiplying by 1, it leaves the expression/number unchanged.
So yes, polynomial of degree zero is a constant term
Answer:
Step-by-step explanation:
Let the length be :x+7
Let the breadth be:x
After addition and subtraction
Length:x+7+2=x+9
Breadth:x-1
A.T.Q
x(x+7) = (x+9)(x-1)
x²+7x = x(x-1)+9(x-1)
x²+7x = x²-x+9x-9
x²+7x-x²+8x = 9
8x-7x = 9
So, Breadth: 9m
So, Length :16m
17 would be the answer, you divide 30 by 1.75 and you get 17.14 but you can’t buy .14th of a book so you’re left with 17
