8x-2= -5+7x
2x= 2x
So you start with one side of the problem and solve it by writing it below. Then do the other side. In the end, they should equal each other
You need to replace x with 5 so it will be…
[3(5) + 4] - (2 - 5)
(15 + 4) - (-3)
19 + 3
22
Answer:
<4 = 63°
Step-by-step explanation:
32° + 31° = < 4 ( exterior angle of a triangle is equal to the sum of two opposite interior angles)
<4 = 63°
Hope it will help :)
Round the numbers to the nearest whole tens
625 close to 630
248 is close to 250
630-250= 380
The estimated difference is 380.
Hope this helps!
