1:3:4
1x:3x:4x
1x + 3x + 4x = 8x
8x = 56
x = 7
1(7) = 7
3(7) = 21
4(7) = 28
Check: 7 + 21 + 28 = 56
So 56 can be divided in the ratio of 1:3:4, and it will be 7, 21, 28
Answer:
divide 10 by both sides so your answer is 8
Step-by-step explanation:
12 - (-2) (-4)
-2 * -4 = ?
A negative times a negative equals a positive value.
-2*-4 = 8
12 - 8 = ?
12-8 = 4
Because 4+8 = 12
Final answer: 4
In doing this division, we will first divide the 8.6 by the 3.2 to get 2.6875. Thankfully, that number is already in scientific notation so we don't have to worry about changing it. Now for the rest of the problem. When the bases are the same, and they are both 10's, you subtract the exponents.

gives us 10^5. The answer then in scientific notation is
