Answer:

  1. 7-5 => 2
  2. -7+5 => -2
  3. -7-5 => -12
  4. 7-(-5) => 12

Step-by-step explanation:

Lets solve the expressions one by one

<u>1. 7-5</u>

we can see that it is simple subtraction. A smaller number is being subtracted from a large number.

So the answer is 2

<u>2. -7+5</u>

There are two numbers with different signs. When there is a number with plus and a number with minus both quantities are subtracted but the larger quantity determines the sign of the answer.

In this case, 7 is larger and has negative sign, the answer will be -2

<u>3. -7-5</u>

When there are two numbers with minus sign they are added but the answer has the minus sign with it.

So the answer will be: -12

<u>4. 7-(-5)</u>

When minus is multiplied with minus it converts to positive

So

= 7-(-5) = 7+5 = 12

Hence,

  1. 7-5 => 2
  2. -7+5 => -2
  3. -7-5 => -12
  4. 7-(-5) => 12

Find the value of y in the equation attached to this question
dlinn [17]

Answer:

y = 4

Step-by-step explanation:

1) Simplify 3^5 to 243.

{9}^{y}=\frac{243\times {9}^{6}}{{27}^{3}}

2) Simplify {9}^{6} to 531441.

{9}^{y}=\frac{243\times 531441}{{27}^{3}}

3)  Simplify  243\times 531441 to  129140163.

{9}^{y}=\frac{129140163}{{27}^{3}}

4) Simplify  {27}^{3}  to  19683.

{9}^{y}=\frac{129140163}{19683}

5) Simplify  \frac{129140163}{19683} to 6561.

{9}^{y}=6561

6) Convert both sides to the same base.

9^y=9^4

7)  Cancel the base of 9 on both sides.

y=4
