If m 2 n, which inequalities must be true? Check all that apply. Om + 2.1 > n + 2.1
m - (-4) 2 n-(-4)
m + 3 n-3
16.5 + m > 16.5 + n
1
U
m 2 n +
U
9 + m > 6+n

Step-by-step explanation:

Given

Required

Select true inequalities

Subtract 2.1 from both sides

This is true

Open brackets

Subtract 4 from both sides

This is also true

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3

each side has a different length.
