Answer:
Step-by-step explanation:
Solve the system:
8x−4y=20
4x−8y=4
Reduce the first equation by dividing every term by -2:
-4x + 2y = -10
and then combine this result with the second equation:
4x−8y=4
-4x + 2y = -10
--------------------
-6y = -6, and so y = 1.
According to the first equation, if y = 1, then 4x - 8 = 4, or x = 3.
Then x = 3 and y = 1.
So, finally, x - y = 3 - 1 = 2
To turn a decimal into a percentage, multiply the decimal by 100 and add a percent sign.
.166 x 100=16.6
And add a percent sign
16.6%

Answer:
752
Step-by-step explanation:
IN these type of questions we put the numbers in descending order
93% of 149
10% of 149 = 14,9
93% of 149 > 90% of 149
93% of 149 > 149 - 14,9 ≈ 149-15≈134
> 134
⇒ the answer is D
