Tell which variable you would choose to eliminate when solving the system by eliminating. Then solve the system by elimination -8x-6y=18
9x+6y=-24​

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n
