-3 x 13 super easy its all about negative and positives sign
Answer:
x = 18
Step-by-step explanation:
By the rule of Consecutive Interior Angles which define what these angles are, they both will add up to 180. As such we can put the sum of these two angles set equal to 180, and solve algebraically
(8x - 20) + (3x + 2) = 180
8x - 20 + 3x + 2 = 180
11x - 18 = 180
<u> + 18 +18</u>
11x = 198
x = 198/11
x = 18
Half of 3600 ft^2 is 1800 ft^2 and 2/5 of 3600 ft ^2 is 1440 ft^2 so 1800 plus 1440 is 3240 ft^2 so 3240 ft^2 of the yard is now mowed
Answer:
1/36
Step-by-step explanation:
1/6 for the inital four, one in sixth chance to continue the roll on another 6.
the likely hood of making both these (on the first try) is 1/6*1/6 = 1/36.
Answer:
|8|
Step-by-step explanation:
Let the integer = x
x = - 2x - 24
x + 2x = - 24
3x = - 24
x = - 24/3
x = - 8
Hence, the integer is - 8
The number could be the positive of negative of 8
Hence, it is better expressed as |8|
