Solve each equation by graphing. Verify your answer algebraically.
2. – X – 3=0

Answer:

1). 6x +7 = 4x +19

6x – 4x = 19 – 7

2x = 12

x= 12/2

x= 6

2). 3x + 3 = 7x – 5

7x – 3x = 3 +5

4x = 8

x= 8/4

x = 2

3). 39 – 2v = 3v + 4

3v +2v = 39 – 4

5v = 35

v = 35/ 5

v = 7

4). 4n + 6 = 18 – 2n

4n +2n = 18 – 6

6n = 12

n = 12/ 6

n = 2

I hope I helped you^_^

Answer:

CP = 11000

Step-by-step explanation:

Given,

SP = 9900

Loss% = 10

-----------------------------------------------

Let the CP be y,

[tex] \bold{ cp = \frac{(sp \times 100)}{(100 - loss\%)} }[/tex]

[tex]⇒ \bold{y = \frac{(9900 \times 100)}{(100 - 10)} }[/tex]

[tex] ⇒\bold{cp = \frac{9900 \times 100}{90} }[/tex]

[tex]⇒ \bold{cp = 11000}[/tex]

Step-by-step explanation:

Answer: 238 rulers

Step-by-step explanation:

Box A=225 pens and box B= 320 rulers

Things in box A=x and things in box B=y (because box A items are over 10 and items in box B are over 5)

Box A = 3/10 are pens (all items in this box are called x)

x + x + x = 3x

y +y+y+y+y+y+y = 7x (rulers moved from box B)

Box B = 3/5 pens

x + x + x = 3y (pens)

x + x = 2y (rulers)

System of equations:

3x + 3y = 225 and 7x + 2y = 320 (simplify the first equation, divide by 3 and multiply by -2 to cancel 2y)

(3x+3y=225)/3 = x+y=75

-2(x+y=75)= -2x-2y= -150

Add both equations

(-2x-2y= -150) + (7x+2y=320) =

5x = 170

X = 34

7*34=238

Answer:

90.

Step-by-step explanation:

7m - 3 = 53

m would be 8 because 56 - 3 = 53.

11m + 2 equals 90 because 11 times 8 (8 is m) is 88, which added by two is 90.
