Answer:
2x4-6
Step-by-step explanation:
2x4 is 8, and 8-6=2. Therefore 2x4-6=2
x - y = - 11 .............( 1 )
y + 7 = - 2x ...............( 2 )
from equation ( 1 )
x - y = - 11
x = -11 + y ...........( 3)
putting x in equation ( 2 )
y + 7 = - 2 x
y + 7 = -2 ( -11 + y ) y + 7 = 22 - 2 y y + 2 y =22 - 7
3 y = 15 y = 15 / 3
putting value of y in equation 3
x = -11+ ( 13 /5 ) x = -33 /3 + 15 / 3 ( l.c.m)
x = -17 / 5
check
x = -11 + y
- 17 / 5 = -11 + 13 / 5
-17 /5 = -17 / 5
Answer: 147°
Step-by-step explanation:
A straight line is equal to 180° which means we can subtract 33° to find the value of <em>x</em>.
180° - 33° = 147°
<em>x</em> = 147°
The simple way to double something more than once is to multiply the original number by 2 and then double the product until the final amount of doubles has been reached, in this case, 3. Doubling 33 3 times, we get 264
