X will represent unknown
2x-4<3x
treat the < sign as a = sign
2x-4=3x
subtract 2x form both sides
-4=x
put the < sign back
-4<x
-4 is less than than x or
x is greater than -4
In this equation, you have to treat the number in the bracket first on the basis of BODMAS
15 - [-3]- 4
Note that when two minuses come together the product is a plus sign.
15 +3 - 4
You have to add before you subract
18 - 4 =14
Therefore, 15- [-3] - 4 = 14.
78
step by step explanation:
first: divide 600 and 15
answer to 600/15: 40
second: divide 3120 and 40
final answer: 78
I don’t think so but divide the top one by the bottom one for every one of them and if it is all the same answer they are proportional x/y
