Answer:

X = 65.

Step-by-step explanation:

The range is the greatest number - least, so we have:

X - 12 = 53

X = 53 + 12 = 65.

Select the equations whose graphs are parallel to the graph of the equation y=23x+5.
iren [92.7K]

Answer:

2x-3y=9    and    4x-6y=30

Step-by-step explanation:

hello :  

note y=(2/3)x+5  no y=23x+5

2/3 is the slope....... all lines parallel to this line has same slope.

1)   2x-3y=9   means : 3y = 2x-9   divide by 3 : y=(2/3)x-3..same slope.

2)  4x-6y=30  means : 6y= 4x-30 divide by 6 : y=(4/6)x -30/6

but 4/6 = 2/3 so : y=(2/3)x-5..same slope.

Emily has some $5 bills and $10 bills she has 15 bills she has $120 how many $5 bills does she have​
Alexxx [7]

Step-by-step explanation:

Let F = The number of $5 bills and T = the number of $10 bills.  She has 15 bills total, so:

 

F+T = 15                

T = 15-F

 

She has $120 total:

 

$120 = ($5)*F + ($10)*T

$120 = $5*F + ($10)*(15-F)         [Substitute 15-F in place of T]

120 = 5F + 150 - 10F

-30 = -5F

 

6 = F

 

Check:

T= 15-F = 15=6 = 9

 

$120 = ($5)*6 + ($10)*9

$120 = $30 + $90

$120 = $120

Factorise x2 + 13x + 42
kirill [66]

Answer:

you can use the formula "<em>Cross method" </em>  in which the last number of the equation is the sum of 2 number multiplication that also sums the 2nd num of the equation.

so it becomes

(x +6)(x +7)

WHY?

Bcs when u multiply 6 x 7 = 42 ( the last number of the equation)

      when u sum 6 + 7 = 13 ( the 2nd number of the equation)

Hope this helps :)
