Answer:
-9
Step-by-step explanation:
Adding a negative 3 is the same as subtracting 3, so if you do -6 - 3 you get -9
Step by step: -2x + 3= 13
-3 = -3
-2x = 10 divide -2 on each side and get -5, so x=-5, plug that in 2x would be 2( -5) would be -10
ANSWER: -10
First, 0.0004853 is < 1, so we need to multiply the number by 10 to a negative power if it's greater than 1 (if that makes sense i cant describe it better)
So, b and c is incorrect.
10 to the power of negative 4 = 0.0001, and 4.853 x 0.0001 = 0.0004853 (true), so answer is a
Get the equation simplified. Subtract 4 by each side.
20-4= 16
and the square root of 16, is 4.
Plug it in to check.
(4)^2+4=20
16+4=20
20=20
Ultimately your final answer is X=4
3/15 equals 1/5 because 3/3=1 and 15/5=5. So B is the correct answer. 1/5
