Answer:
ET = 80/A^2
Step-by-step explanation:
First, isolate the variables that you need, which is E and T, using the two equations you were given.
EA = 8
E = 8/A (divide A on both sides to isolate E)
AT = 10
T = 10/A (divide A on both sides to isolate T)
Now, substitute.
ET --> (8/A) x (10/A) = 80/A^2
Answer:
0
Step-by-step explanation:
To solve this, you first plug in the 4 and 2 where the x and y's go, making the expression (4 - 2(2))*(4 + 2(2)). Then you solve each parenthesis (below).
(4 - 2(2))*(4 + 2(2)).
(4 - 4)*(4 + 4).
0*8

➷ Split 84 into two numbers that can be multiplied to give 84
42 x 2 = 84
2 is a prime number so we don't need to simplify it further, however, 42 isn't a prime number.
42 can be split into :
21 x 2 = 21
So far, we have 21 x 2 x 2 = 84
The 21 can be split further:
7 x 3 = 21
Therefore, the answer is 7 x 3 x 2^2

Answer:
52.329km/hours
Step-by-step explanation:
x = speed
100/x - 100/(x+5) = 1/6
==> x= (5sqrt(481)-5)/2 = 52.329km/hours
0.75*3.5a = 2.625a
0.75*6b = 4.5b
2.625a - 4.5b is our final answer
