Are these expressions equivalent 5+3x-2 and 2(x+1)+1 with x=3 and x=7

b.an increase in a causes b to decrease

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
