Answer:

Elevation of Zero feet, Means

If represented on number line , it is in middle of Number line equidistant from both sides.

=At sea level

→Integer={------,-3,-2,-1,0,1,2,3,..............},

0 is in the middle of integers, that means neither positive nor negative.

→Elevation above Zero Feet=Positive Integer

→Elevation below Zero Feet=Negative Integer

Answer:

i, m, and then k (use my method to do the other one)

Step-by-step explanation:

The longer than angle the longer the side tht is opposite to it... so for example, each angle and its opposite correspond to each other.. so K it is side K and so on...

first u should find the missing angles, for A, we know the angles 118 and 28 and a triangle is a total of 180 degrees, so add 118 and 28, which will give u 146, now subtract tht from 180 and u get 34, so the missing angle M is 34, now we can see which angles correspond to which side:

K = k

M = m

L = l

so the shortest will be l, then it will be m, and then it will be k

After solving the system of equations, x= -3 and y=6

Step-by-step explanation:

We need to solve the following system of equations by substitution.

$-3x + y = 15\,\,\,(1)\\-8x-7y = -18\,\,\,(2)$

Finding value of y from equation(1) and substituting it in equation(2)

$y=15+3x\\substituting\,\,in\,\,equation(2)\\-8x-7(15+3x)=-18\\Solving:\\-8x-105-21x=-18\\-8x-21x=-18+105\\-29x=87\\x=\frac{87}{-29}\\x=-3\\$

The value of x is x=-3

Now, Finding value of x from eq(1) and substituting in equation(2)

$-3x=15-y\\x=\frac{15-y}{-3}\\Substituting\,\,in\,\,equation(2)\\-8(\frac{15-y}{-3})-7y=-18\\\frac{120-8y}{3}-7y=-18\\\frac{120-8y-7y*3}{3}=-18\\\frac{120-8y-21y}{3}=-18\\\frac{120-29y}{3}=-18\\120-29y=-18*3\\120-29y=-54\\-29y=-54-120\\-29y=-174\\y=\frac{-174}{-29}\\y=6$
