Answer:
Step-by-step explanation:
5/8
Answer: 4/10
Step-by-step explanation: easy
6/2=4
8/2=4X10=40 .
now...
40/4= 10
so its simply 4/10
I’m pretty sure it will be 7+12 and 12+7
When the first equation is multiplied by -3, the sum of the two equation
and any of the original equations will have the same solution as the
original equations. Hence 5x = -10 and 11x - 9x = -13 will have a
solution of (-2, -1).
Answer:
B
Step-by-step explanation:
To multiply scientific notation, multiply each part of the number.
(9 x 10)^2(2 x 10)^10 = (9*2) * (10^ 2 + 10) = 18 * 10 ^ 12
Since scientific notation can only have a digit in the ones place from 1-9. 18*10^12 becomes 1.8*10^13.
The solution is B.
