Step-by-step explanation:

5) 2.4×10^-5 / 4.5×10^-11

2.4×10^-5= 0.000024
4.5×10^-11= 0.000000000045

=0.000024/0.000000000045

=24/1 × 1,000,000/45

=24,000,000/45

=533,333.33°

=5.33333°×10^5

**NOT SURE ABOUT THIS QUESTION

6) (4,-2)

7) --------

8)

2x + 3 = 5x - 2

2x - 5x = - 2 - 3
-3x = -5
x = -5/-3
x = 1.66°

6x + 4 = 6x + 4

6x - 6x = 4 - 4
0x = 0

2 (2x + 3) = 8x - 2

4x + 6 = 8x - 2
4x - 8x = -2 - 6
-4x = -8
x = -8/-4
x = 2

-3x + 2 = -3x + 5

-3x + 3x = 5 - 2
0x = 3

Letter be has no solution because it is broken down as "0x = 0"

What is the value of y in this system of equations: 3x + y = 9 y = –4x + 10 ?

Ahat [919]

3x + y = 9 (I)
y = –4x + 10 (II)
------------------------
 $\left \{ {{3x + y = 9 } \atop {y = -4x + 10 }} \right.$

Pass the incognito "4x" to the first term, changing the signal when changing sides.
-------------------------
simplify by (-1)
 $\left \{ {{3x + y = 9.(-1)} \atop {4x + y = 10 }} \right.$ 

-------------------------
 $\left \{ {{- 3x - \diagup\!\!\!\!y =-9} \atop {4x + \diagup\!\!\!\!y = 10}} \right. 
$

-------------------------
 $\left \{ {{- 3x = - 9} \atop {4x = 10}} \right.$ 

-----------
 $\boxed{x = 1}$ 

Substitute in equation (I) to find the value of "Y".

3x + y = 9 (I)
3*(1) + y = 9
3 + y = 9
y = 9 - 3
$\boxed{y = 6}$

Answer:
$\boxed{\boxed{ \left \ {{x=1} \atop {y=6}} \right. }}$
