5x-2+3x-4 = 2x-8+x+2
First we have to put all X's on side and the remaining numbers on the other, changing their signal if they move across the equal sign. Therefore,
5x+3x-2x-x = -8+2+4+2
5x = 0
x= 0/5
x= 0
Answer:
x=-9
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-8-(-6))/(-9-(-9))
m=(-8+6)/(-9+9)
m=-2/0
undefined
x=-9
Answer:
h = 2.7 m
Step-by-step explanation:
ΔADE and ΔABC are similar, hence ratios of corresponding sides are equal
DE / BC = AD / AB, that is
h / 0.9 = 18 / 6 ( cross- multiply )
6h = 16.2 ( divide both sides by 6 )
h = 2.7
Answer:
The sales price of the skirt was $14.3.
Step-by-step explanation:
From the information given, you know that the total for the three items is $32.35 which is:
x+y+z=32.35
x is a skirt
y is a pair of shoes
z is a pair of socks
Also, you know that the pair of socks costs $3.75, so you can replace the value of z and subtract this from the total amount to have the price of the skirt plus the pair of shoes:
x+y+3.75=32.35
x+y=32.35-3.75
x+y=28.6
Now, as the original prices of the skirt and shoes were the same and you know that the sum of the two items is equal to $28.6, you can divide this by 2:
$28.6/2=$14.3
According to this, the answer is that the sales price of the skirt was $14.3.
