Answer: 9
Step-by-step explanation:
-3 1/3 x (-2 7/10)
-3 = -3*(3/3) = -9/3
-3 1/3 = -10/3
(-2 7/10)
-2 = -2(10/10) = -20/10
-2 7/10 = -27/10
(-10/3)*(-27/10) = (270/30) = 9
Its 12 because you do 10.5/21=x/24
X = 3*15 = 45
Hope it helped.
It helps to imagine the variable a sort of as a unit. Like with 5 minus 12 lemons, it has no bearings on the addition/subtraction here.
Factor out a and subtract.
Answer:
the answer would be done like this
Step-by-step explanation:
you have to get y by itself so you would need to move the x to the right of the equal sign
once you move anything to the opposite side it switches, so positive becomes negative vice versa
-3y=-x+18
you need to make sure you have positive 1 y so you would divide y by -3 to make it 1
everything else is multiplied by -3 as well
so the answer would be y=⅓x-6
