Answer:
4(-7)
4*-7=-28
Whenever multiplying +positive sign and -negative sign= -negative sign
The answer to this question would be: 6
In this question, you are asked to estimate 90/7 divided by (1 + 3/4). You can convert the 1 3/4 into :
1 +3/4=
4/4 + 3/4= 7/4
Then, the calculation would be:
(90/7) / (7/4)= (90*4)/ (7*7)= 7.347
The distance from 7.347 to 6 would be -1.347. It was much shorter than the distance to 12 which is 4.7. The closest answer would be 6
287 people said they did unless you want decimals its 286.65
Answer:
w = -z(-w) + 3(-w)
Step-by-step explanation:
z = w + 3 | Given
-w + z = 3 | Subtract w from both sides.
-w = -z + 3 | Subtract z from both sides
w = -z(-w) + 3(-w) | Multiply -w on both sides.
