Answer:
{x | x R, x<-12}
Step-by-step explanation:
SO basically think of it as x is a teenager that wants to be alone. so have to figure out how to get everyone on the otehr side of their bedroom door (>)
so you are going to do this
-1/2x>6
/-1/2x /-1/2x
x<6/-1/2
x<6*-2/1
x<-12
Answer:
Christina has 30 quarters and 20 dimes.
Step-by-step explanation:
Given that a quarter is worth 0.25 dollars and a dime is worth 0.10 dollars, if Christina has 50 coins and these add up to a total of $ 9.50, to determine the number of quarters and dimes that she has in her possession, the following calculation must be carried out, taking into account that the difference between a quarter and a dime is 0.15 dollars:
50 x 0.25 = 12.5
12.5 - 9.5 = 3
Thus, the difference between the value that Christina has and the value that she would have if all of her coins were quarters is 3 dollars. Thus, since 0.15 x 20 equals 3, of the 50 coins Christina has, 30 are quarters and 20 are dimes.
This is confirmed through the following equation:
30 x 0.25 + 20 x 0.1 = X
7.5 + 2 = X
9.5 = X
Answer:
(3,-4)
Step-by-step explanation:
3x-7(2x-10)=37
3x-14x+70=37
-11x+70=37
-70 -70
-11x= -33
divide -11 both sides
x= 3
y=2(3)-10
y=6-10
y= -4
