Question

Раскройте скобки и приведите подобные слагаемые: а)c + (-c+d) б)-(3,4 -x)+ (- x +1,6)​

Answer 1

а) с-с+d=d    с-взаимоуничтожаются

б) -3,4+х-х+1,6=-3,4+1,6=1,6-3,4=--1,8

х-взаимоуничтожаются

Answer 2

а) c + (-c + d)

To simplify this expression, we can remove the parentheses and combine like terms:

c + (-c + d) = c - c + d

Now, notice that the terms "c" and "-c" are additive inverses of each other, meaning they sum up to zero. Therefore, c - c equals zero, and we are left with:

c - c + d = 0 + d = d

So, the simplified expression is "d."

б) -(3.4 - x) + (-x + 1.6)

Again, let's simplify the expression by removing the parentheses and combining like terms:

-(3.4 - x) + (-x + 1.6) = -3.4 + x - x + 1.6

Now, we can combine the "x" and "-x" terms:

x - x = 0

Therefore, the simplified expression is:

-3.4 + x - x + 1.6 = -3.4 + 1.6 = -1.8

So, the simplified expression is "-1.8."
