Помогите пожалуйста.Преобразуйте выражение в равное, изменив каким-либо способом порядок слагаемыха) a+b +cб) -x+y-zв) x-a-c+dг) 7+2a-5cд) b-3d+10е) -5m+3n-1

Answer 1

а) а+с+b
б) у-z-x
в) d+x-a-c
г) 7-5c+2a
д)10+b-3d
е)3n-5m-1
Варианты могут быть и другие, ведь от перестановки мест слагаемых сумма не меняется (один из законов сложения). Главное знаки перед числами не менять.

Answer 2

a) a + b + c

To rearrange the terms and make the expression equal, we can change the order of the terms. Since addition is commutative, the order of the terms doesn't affect the result. Therefore, the expression remains equal to a + b + c.

б) -x + y - z

Similarly, for this expression, we can rearrange the terms without changing the result. The expression remains equal to -x + y - z.

в) x - a - c + d

Again, we can rearrange the terms without changing the result. The expression remains equal to x - a - c + d.

г) 7 + 2a - 5c

In this case, the terms are already in the correct order, so we don't need to make any changes. The expression remains equal to 7 + 2a - 5c.

д) b - 3d + 10

Similar to the previous cases, we can rearrange the terms without changing the result. The expression remains equal to b - 3d + 10.

е) -5m + 3n - 1

Once again, we can rearrange the terms without affecting the result. The expression remains equal to -5m + 3n - 1.

In summary, for all the given expressions, we can change the order of the terms without altering the value of the expression.
