Ted is incorrect because 3/10 is the same as .30 which is then multiplied by 100 and given the product of 30.
.3×100=30
In order to answer the question, it's absolutely essential to have
enough of a description of the object to know which of its parts
'X', 'Y', and 'Z' are, and what other parts it may have.
An ideal way to accomplish this would have been for you to include the
picture that accompanies the question, wherever you copied it from.
Answer:
11 + 2x
Step-by-step explanation:
In algebra, like terms are terms that have the same variables (letter after the number). Like terms can be combined for example the 6 and 5 have the same variable (none) so they can be combined. IMPORTANT! While we do combine the 2x and the 4x since the 2x came after a minus sign we consider it a negative, so -2x + 4x (or 4x - 2x) is 2x NOT 6x
The answer is simple
First find the angle measures of first triangle:
statement:
we know that the sum of 45 and 30 sums up to the opposite angle and that is equal to 75, then to find the next remaining angle:
180-(75+20)=85
The you find the supplement of 85:
180-85=95
so x = 95
Hope it helps
It's the first one, an algebraic expression contains variables
