Answer:
-0.9
Step-by-step explanation:
(-(2 2/5) / (8/3)) = - 0.9
6 total beads
1 is yellow
1 is blue
1/6 of getting a yellow
1/6 of getting a blue and
1/6 of getting a yellow again
1/6 * 1/6 * 1/6 = 1/216 probability
Answer:
x=0.5 and y=5
Step-by-step explanation:
8x+7y=39...eqn(1)×-14
4x-14y=-68...eqn(2)×7
we now have,
-112x-98y=-546
-(28x-98y=-476)
-140x÷-140 =-70÷-140
x=0.5
to solve for y, we substitute (x=0.5) into eqn (1) or eqn 2 which ever you want...
so I'm using eqn 1.
8x+7y=39
8(0.5)+7y=39
7y=39-4
7y÷7=35÷7
y=5
therefore, x=0.5, y=5
proof: substitute both x and y values to get you the same answer as the original solutions in both equations.
we have,
8(0.5)+7(5)=39
4(0.5)-14(5)=-68
Part A: Tanisha
This is because of slope, in 2 months Tanisha has $30 while Avery receives $12 a month.
The answer to this is d.) 1. This is because any number that is raised to the zero power is 1.
