Step-by-step explanation:
12:15 = 8:X
X=cardboard box shadow
you find x by treating this equation like a proportion.
![\frac{12}{15} = \frac{8}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B12%7D%7B15%7D%20%3D%20%20%5Cfrac%7B8%7D%7Bx%7D%20)
so 15(8)÷12=x
X=10
Silently he crept through jagged thornbushes. Bare feet moved swiftly over hot, arid soil to the edge of a waterhole where the kudu was drinking. The great animal suddenly looked up, spiral horns curving sharply into the endless African sky. Nsue1 did not reach for his pouch of poisoned arrows. He had no heart for killing. This would not be the day he would change his childish boyhood name.

A.
It establishes Nsue’s disappointment at not finding a suitable animal to bring to the feast.
B.

C.
It establishes Nsue’s desire to become a great storyteller like Gao, the Old One.
D.

Answer:
Option 3:
elimination using multiplication (3,-1)
Step-by-step explanation:
The system of equations to be solved are
-5x+3y=-18.......eqn (1)
2x+2y=4. .......eqn (2)
We first multiply eqn(1) by 2 and eqn(2) by 5 to get eqn(3) and eqn(4) respectively.
This implies
-10x+6y=-36.......eqn (3)
10x+10y= 20.......eqn (4)
we then add eqn(3) and eqn(4) to obtain
16y=-16
We divide through by 16
![\implies \frac{16y}{16}= \frac{16}{16}](https://tex.z-dn.net/?f=%20%5Cimplies%20%5Cfrac%7B16y%7D%7B16%7D%3D%20%20%5Cfrac%7B16%7D%7B16%7D%20%20)
![\implies y = - 1](https://tex.z-dn.net/?f=%5Cimplies%20y%20%3D%20%20-%201)
Putting the value of y into eqn(2)
![\implies 2x + 2( -1 ) = 4](https://tex.z-dn.net/?f=%20%5Cimplies%202x%20%2B%202%28%20-1%20%29%20%3D%204)
![\implies 2x - 2= 4](https://tex.z-dn.net/?f=%5Cimplies%202x%20-%202%3D%204)
Adding 2to both sides
![\implies 2x - 2+ 2 = 4 + 2](https://tex.z-dn.net/?f=%5Cimplies%202x%20%20-%202%2B%202%20%3D%204%20%2B%202)
![\implies 2x= 6](https://tex.z-dn.net/?f=%5Cimplies%202x%3D%206)
Dividing through by 2
![\implies \frac{2x}{2} = \frac{6}{2}](https://tex.z-dn.net/?f=%5Cimplies%20%20%5Cfrac%7B2x%7D%7B2%7D%20%3D%20%20%5Cfrac%7B6%7D%7B2%7D%20)
![\implies x = 3](https://tex.z-dn.net/?f=%5Cimplies%20x%20%3D%203)
Hence, (x, y)=(3,-1)
D. 15+18
Hope that helps!
