Answer: Please include more information, for now this is indeterminable
Step-by-step explanation: Sorry, add more info and I will be sure to answer
<span>4x + 3y = 16
7x + 6y = 31
Note what happens if we mult. the first eqn. by -2:
-8x - 6y = -32
Combining this with the 2nd equation eliminates the variable y:
</span>-8x - 6y = -32<span>
7x + 6y = 31
--------------------
-x = -1, or x = 1. Sub 1 for x in either of the 2 given eqns to find y:
For example: 4(1) + 3y = 16, so 36 = 12, and y = 3. Sol'n is (1,3).</span>
Answer:
c = sqrt 13.4689 rounded to sqrt 13.5 = 3.5
Step-by-step explanation:
maybe A+ B totals sqrt 13 = 3.60555128 if so they have rounded down for c to = 9 then 6 + 8 added on ay = sqrt 6+ 8 = sqrt 14 = sq rt 3.74165739 in all effect if triangular = average of a= b = 3.67^2 = 13.4689 then through Pythagoras c = sqrt 13.4689 rounded to sqrt 13.5 = 3.5
