3x + (-2x) would be just subtracting 2x from 3x, so it would be 1x or x. Hope this helped<3
To find the distance between 2 numbers you must take the absolute value of the difference
|90-(-20)|
|110|
110
110 degrees celsius
Answer:
C
Step-by-step explanation:
interior angle + exterior angle are supplementary
interior angle = 180° - exterior angle
⇒ interior angle = 180° - 135° = 45°
and interior angle = 180° - 100° = 80°
The sum of the 3 angles in a triangle = 180°
To find the third interior angle, subtract the sum of the 2 interior angles from 180
third interior angle = 180° - (45 + 80 )° = 180° - 125° = 55°
interior angles are 45°, 55° and 80°
Its a because you will add 1.25 and 0.75 because it says each and of course 18 would be what it equals
Answer:
-7
Step-by-step explanation:
given f(x)=4x+k
therfore, f(2)=4*2+k
we know that f(2) =1
so, 4*2+k=1
8+k=1
k=1-8
k=-7
