Step-by-step explanation:
this is an improper fraction to make it mixed you have to find how many 20s are in 23
yea only one
so 1 is the whole number
then it is 1 3/20
you can again make it improper by multiplying denominator by 1 and adding 3
We have that
an=<span>10 * 5n---------------> an=50*n
then
for n=1
a1=50*1=50
</span>for n=2
a2=50*2=100
for n=3
a3=50*3=150
for n=4
a4=50*4=200<span>
the answer is
</span><span>the first four terms are [50,100,150,200]</span><span>
</span>
The answer is 1.92 x 10^6
Answer:
C. 
Step-by-step explanation:
{y = ¼x - 3}
{2x + 4y = 12
2x + 4[¼x - 3] = 12
2x + x - 12 = 12
3x - 12 = 12
+ 12 + 12
_________
3x = 24

3 3
[Plug this back into both equations above to get the y-coordinate of −1];
