Answer:
24
Step by-step explanation:
6x=3x-1+13
common like terms (-1+13)
6x=3x+12
subtract 3x on both sides
3x=12
divide 3x on both sides
x=4
insert 4 into equation 6*4=24
3(4)-1+13=24
Either or can be used with any triangle...I personally find the law of sines is often more compact as in this case we can just say;
(sin115)/18=(sin40)/c (with no need for b or B as would be needed with the law of cosines...)
c=18(sin40)/(sin115)
c≈12.77
Answer:
5,000,000 and 6,000,000
Step-by-step explanation:
5,000,000 and 6,000,000 is 11,000,000
or 5,000,000 and 5,000,000 is 10,000,000
and the 1 is in the ten millions place in the sum
Answer: y = 9x
Step-by-step explanation:
Li needs to use 9 beads for each inch of necklace.
X = Length of Necklace
Y = Number of beads needed
y = 9x
For instance, assuming a necklace is 8 inches long, how many beads will be needed;
= 9x
= 9 * 8
= 72 beads
