To find t? yes.
First, you combine like terms so 3t and 2t and 4t. Add 3 and 2 and then subtract the 4. you will end up with 1t (just t) +2. you cannot add the 2 because it does not have the variable t. on the other side, you will also combine like terms. so 3+5=8. now your equation is t+2=8. this is the part where you will try to get t by itself. subtract the 2 from the left side. but in order for the equation to stay equal to itself, you have to subtract 2 from the right side as well. this will leave you with your final answer of t=6.
20% of $50 is:
$50* (20/100)= $10.
$50- $10= $40
The new price is $40.
Hope this helps~
Answer:
√2 x √2 = 2
Step-by-step explanation:
Square roots that aren't perfect squares are irrational.
For Ex: √2 is irrational.
But √2 x √2 = √4 = 2. 2 is rational
Ex. 2 : √8 x √2 = √16 = 4. 4 is rational
Answer:
a)
i) we have the equation:
3*x - 2*y
We want to find a common multiple of 3 and 2.
One can be:
3*6 = 18
2*9 = 18
And both numbers 6 and 9 are on the list, then if we take:
x = 6, y = 9
we get:
3*6 - 2*9 = 18 - 18 = 0
The solution is x = 6, y = 9.
ii) The greatest possible value of:
3*x - 2*y
Will be when x is the largest value of the list (because it is on the positive term) and y is the smallest value on the list (because it is on the negative term)
then we need to have x = 10, y = 5
The value will be:
3*10 - 2*5 = 30 - 10 = 20
iii) Now we want to have the smallest value on x, and the largest one on y, then:
x = 5, y = 10
The smallest value of the equation will be:
3*5 - 2*10 = 15 - 20 = -5
B) We want to solve:
5*(a - 4*b)
when:
a = -7
b = 1/4
This is kinda easy, we just need to replace the variables in the equation to get:
5*(a - 4*b) = 5*(-7 - 4*(1/4)) = 5*(-7 - 4/4) = 5*-8 = -40
The given statement "A theorem is a statement that can be easily proved using a corollary" is false.
Answer: False
<u>Step-by-step explanation:</u>
A statement that would be proven on the basis of postulates and before proven theorem is called Theorems. "Corollary", a theorem that should come from a previous theorems (part of another statement). Contrary to the definitions, this may be reversible or irreversible if they are presented in the form "if - then."
Example for theorem: The measured angles of a triangle added to 180 degree.
The theoretical aspects of geometry consists of definitions, theorems, and postulates. Basically, these are elements of geometric proof.
