912 is the correct answer for this question thank you!
Answer:
If you subtract 4 from a, it will be greater than b
Step-by-step explanation:
Ok, so in order to solve this, it would be easier to substitute (a,b) into the equation:
b>a-4
Ok, next, you just have to work out each individual question to see which one is incorrect. You can immediately know it is the first one, and this is because we know that B is larger in this equation, but the problem says that subtracting 4 from a would be greater than b. This is incorrect, b is greater than 4-a, so the top left would be your answer.
Hope this helps!
For this case we must solve the expression given for the variable "m":
We add 5 to both sides of the inequality:
Multiplying by 2 to both of the inequality:
So, finally we have:
The solution is given by all values of m less than 4.
Answer:
1 Simplify a-3a+5a−3a+5 to -2a+5−2a+5
-2a+5-(-a+2b+3)−2a+5−(−a+2b+3)
2 Simplify brackets
-2a+5+a-2b-3−2a+5+a−2b−3
3 Gather like terms
(-2a+a)+5-2b-3(−2a+a)+5−2b−3
4 Simplify
-a+5-2b-3−a+5−2b−3
5 Simplify
-a-2b+2−a−2b+2
