Piper claims that 3(2a + 2) is equivalent to 5a + 6. she checks her claim by substituting -3 for a. is piper's claim correct? why or why not?
i don't know gravity?
option b. 1.93, -11.93 is the right answer.
here the given equation is x²-23 = 10x and we have to solve the equation for the value of x.
first we simplify the equation to bring in the shape of ax²+bx+c=0
x²-23 = 10x
(x²-23)-10x = 10x-10x
x²-10x -23 = 0
now we the formula for the value of
now x = (-5+6.93) = 1.93
and x = (-5-6.93) = -11.93
vanessa´s total pay was $482.50.
we have to add the amount of the 5% commission on vanessa´s sales to her base salary of $400 to find out her total pay.
since the total value of her sales was $1650, the amount (x) of her commission will be:
x = 1650 ×
x = 16.5 × 5
x = 82.50
adding this to her base salary we get:
400 + 82.5 = 482.5
absolute values means always positive. take negative 14 and make it positive
