Answer:

The answer is 5

Step-by-step explanation:

First you subtract 3 from both sides and get 10. Then you divide by 2 and you get 5.

Answer:

x = 8 (but I could be wrong)

Step-by-step explanation:

Add 3 to both sides of the equation

2x=13+3

add 13 and 3

2x=16

Then divide each of the terms by 2 and simplify

Divide 2x = 16 by 2

2x/2 = 16/2

Then cancel the common factor of 2

so 2x/2 (but crossed out) = 16/2

then divide x by 1 x=16/2

then divide 16 by 2

And x=8

Answer:

minimum: 80 zeds

maximum: 137 zeds

Step-by-step explanation:

minimum price is where you choose all the cheapest options

lowest deck price is 40, lowest wheel set price is 14...

40+14+16+10

=40+30+10

=80

maximum price is where you choose all the most expensive options

highest deck is 65, highest price of wheels are 36, hardware 20

65+36+16+20

=65+72

=137

What are the ordered pairs of the

OlgaM077 [116]

Answer:

The two points solutions to the system of equations are: (2, 3) and (-1,6)

Step-by-step explanation:

These system of equations consists of a parabola and a line. We need to find the points at which they intersect:

$x^2-2x+3=-x+5\\x^2-2x+x+3-5=0\\x^2-x-2=0\\(x-2)(x+1)=0$

Since we were able to factor out the quadratic expression, we can say that the x-values solution of the system are:

x = 2 and x = -1

Now, the associated y values we can get using either of the original equations for the system. We pick to use the linear equation for example:

when x = 2 then $y=-(2)+5=3$

when x= -1 then $y=-(-1)+5=6$

Then the two points solutions to the system of equations are: (2, 3) and (-1,6)
