Answer:
61.15702689
Step-by-step explanation:
= 1 / 6 (49/9-14/3) + 27 / 73 / 5 × 33
= 1/6 x 7/9 + 61.02739726
= 61.15702689 = 61.16 (2 d.p.)
Answer:
4(-9)= -36
Step-by-step explanation:
Since there's a negative on the 9 it will affect the product. So the answer is supposed to be a - 36.
Solution
For this case we can do the following:
11y - 3x = 18
16y -3x = 33
We can multiply the first equation by -1 and we got:
-11y +3x =-18
16y -3x = 33
_______________
16y -11y = 33-18
5y = 15
y= 15/5 = 3
And then solving for x we got
x = -(18 -11*3)/ 3= -15/3 = 5
