Which of the following expressions is equivalent to a+(– b)? Select all that apply.

Setler79 [48]

Answer: first option.

Step-by-step explanation:

Given the expression:

$a+(- b)$

You need to remember the multiplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-$

Then, you know that:

$a+(- b)=a-b$

So, an equivalent expression must have $a$ and $-b$ . Let's check the expressions provided in the options:

$(- b ) + a=-b+a \\\\b + (-a)=b-a \\\\(-a ) + b=-a+b$

You can observe that the equativalent expression is:

$(- b ) + a$

${8}^{ \frac{5}{3} } \\ = { ({2}^{3} )}^{ \frac{5}{3} } \\ = {2}^{3 \times \frac{5}{3} } \\ = {2}^{5} \\ = 32.$

Here, we have converted 8 to 2³.

Then, we have used formula (a^m) ^n = a^mn.

Answer:

Step-by-step explanation:

3x - y = 17 .......A

10 × [x/5 + y/2] = 10 × 0

2x + 5y = 0 .......B

......A× 5 both 2 sides of equation

15x - 5y = 85 .....C

......B + ........C

2x + 15x = 0 + 85

17x = 85

x = 85/17

x = 5

put x value in ........A or .......B or ......C

you will receive y = -2
