Answer:
180-1(2x-40)
180-1(2x)+(-1)(-40)
180+−2x+40
Combine Like Terms:
180+−2x+40=(−2x)+(180+40)
-2x+220
Step-by-step explanation:
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 11.17 m. The formula for finding an arc length is y/360 (2piR) where y is the angle and R is the radius. 80/360 (2pi(8)) = 11.17
Answer:
the answer is B- y=65x C- y=70x D-y=80x
Step-by-step explanation:
Answer:
51°
Step-by-step explanation:
Note that the square in the angle place = 90°.
Also note, that a complete circle is 360°.
Set the equation. Let the ? be denoted by the variable x:
x + 90+ 124 + 95 = 360
Simplify. Combine like terms:
x + (90 + 124 + 95) = 360
x + (309) = 360
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 309 from both sides of the equation:
x + 309 (-309) = 360 (-309)
x = 360 - 309
x = 51
51° is your answer.
