Answer:
12.42 -(-4.8) = 17.22
Step-by-step explanation:
1. The most important thing to note is the double negative signs, separated by the paranthesis. When 2 signs, numbers, variable, etc... are separated by a ( ) or simply beside each other, such as 2x or 4(6), you would multiply the 2 numbers.
2. In this equation, note that the negative sign is directly beside the (4.8):
(-)(-4.8) This means that you would multiply the negative sign or -1 by the -4,8. Remember multiplication rules with signs: a negative (-) number x a negative (-) number = a POSITIVE number.
3. Therefore, (-)(-4.8) is looking at the problem as (-) x (-4.8) = +4.8.
4. Note that at this point, the equation becomes an addition problem:
12.42 + 4.8 = x
5. Use your calculator to solve or the CORRECT way of simply lining up the decimals, and, there's your answer:
12.42 + 4.8 = 17.22
Answer:
160 is greater than 2 and a half minutes.
Step-by-step explanation:
-4 2/5 / -5
-4 2/5 = -22/5
-5 = -5/1
-22/5 / -5/1
Flip -5/1 to multiply
-22/5 x 1/-5
Numerator x numerator / denominator x denominator
-22 x 1 = -22
5 x -5 = -25
-22/-25 = 22/25
The answer is 22/25.
1/4 of 12 simply means that if there are 4 equal quarters in 12, how many would be in each of those quarters, or 1/4*12 or 12/4. 12 divided by 4 means that the 12 is on the top and 4 is on the bottom, meaning 12/4.
Plot a point at the y-intercept of -2 or y = -2
--------------------------------------------------------------------
From there make a straight horizontal line
---------------------------------------------------------------
Then Shade the upper-half of that line one color This shaded part stands for
Y > -2
-----------------------------------------------------------------------
Shade the lower half a different color, this stands for y ≤ 6
-------------------------------------------------------------------------
That should be it!
