Corresponding measures have the same ratio.
.. (x -1)/4 = (2x +1)/10
.. 5(x -1) = 2(2x +1) . . . . . . multiply by 20
.. 5x -5 = 4x +2 . . . . . . . . eliminate parentheses
.. x = 7 . . . . . . . . . . . . . . . add 5 -4x

x = 7

vodka [1.7K]

M= (7-1)/(2-0)=3
y=3x + c
plug in Q
1= 3 x 0 +c
=> c =-2
=> the equation represents line QR is y=3x -2

If an item that originally cost $13 is increased to $19, what is the percentage of increase in the item?

Evgesh-ka [11]

Original cost (OC) = $13

New cost (NC) = $19

Percentage increase = $\frac{NC - OC}{OC} *100 = \frac{19 - 13}{13} * 100 = \frac{6}{13} * 100$

= 46.15 %

Give a brief explanation as to what kind of solution you expect for the linear equation 18x +1/2 equals 6(3x +25). Transform the

Makovka662 [10]

Answer:

there cannot be any solution of the given linear equation.

Step-by-step explanation:

i) the linear equation of 18x + $\frac{1}{2}$ = 6(3x + 25)

ii) transforming the equation to a simpler form we get

18x + $\frac{1}{2}$ = 18x + 150 which implies that $\frac{1}{2}$ = 150 which is not true.

iii) therefore there cannot be any solution of the given linear equation.
