That would be 8, its in the center so forget 9 or 7.
Answer:
3/4
Step-by-step explanation:
a1 = (-1/3)^0 = 1
r = -1/3
Hence S = 1/(1+1/3) = 1/(4/3) = 3/4
<h2>L+T = 8</h2><h2>T = 2L -1</h2>
Step-by-step explanation:
Let the number of lions be represented by L
Let the number of tigers be represented by T
<u>A zoo has a total of 8 lions and tigers</u><u> </u><u>:</u>
<u>
</u>
<u>Th</u><u>e number of tigers are one less than twice the number of lions.</u><u> </u><u>:</u>

Answer:
4.95 and 2.25
Step-by-step explanation:
x+y=7.2
x-y=2.7
Add equations
x+y + x-y= (2x-y+y)=2x
7.2+2.7=9.9
Therefore 2x=9.9 x=9.9/2=4.95
x=4.95
x+y=7.2
4.95+y=7.2
y=7.2-4.95=2.25
y=2.25
