Answer:

2x - 2y = 14

x - y = 2

1.) x = 2+ y

2.) 2(2+ y) - 2y = 14

3.) 4 + 4y - 2y = 14

4.) 4y - 2y = 14 - 4

5.) 2y = 10

6.) 2y/2 = 10/2

7.) y = 5

x - y = 2

8.) x - 5 = 2

9.) x = 2 + 5

10.) x = 7

Therefore, x = 7 and y = 5

Step-by-step explanation:

1. First make one of the variables in any equation the subject of the formula

2. Then substitute the variables equating to the subject of the formula

3. Group the like terms,then solve the equation.

4. Replace the value you will find in the first equation into the other equation.

5. Repeat with the same

QveST [7]

Answer:

number one.  186in^{2}  number two.  36cm^{2}

Step-by-step explanation:

FOR NUMBER ONE:

the area of a trapezoid formula is   \frac{a+b}{2} h where a and b are the bases and h is the height. so we have to add in the numbers into the formula

\frac{12+15}{2} * 6\\ = <em>81</em>

and the paralellogram formula is b×h.  where b is the base and h is height

15 × 7 = <em>105</em>

so the area of the figure is 81 + 105 is 186 in^2

FOR NUMBER TWO:

the area of the square formula is s^{2}.   where s is the side

4^2 = <em>16</em>

and for the paralellogram is b × h

4 × 5 = <em>20</em>

so the area of the figure is 16 +20 = 36 in^2

hope this helps! ;)

HELP! SIMPLIFY!
Vitek1552 [10]
1)  (m³n⁵)(mn⁴)
     -----------------
      m⁻³n²

Simplify.

m⁴n⁹
-------
m⁻³n²

When the bottom power is a negative, you add it to the power on top, & when the power is a positive, you subtract it.

m⁴ + m³ = m⁷

n⁹ - n² = n⁷

So, our answer for #1 is m⁷n⁷

2)  6a²b³
     ---------
        4a

Please read rules in #1.

6 / 4 = 3/2 & a² - a = a

So, our answer is 3a
                               -----
                                 2

3)  5⁶a⁶b³
     ---------
       5²ab³
5⁶ - 5² = 5⁴ AND a⁶ - a = a⁵ AND b³-b³ = 0

So, our answer is 5⁴a⁵

Simplify 5⁴

5 × 5 × 5 × 5 = 625

So, our final answer is :

625a⁵

~Hope I helped!~
