Answer:
How much is the discount?
=$70
What is the final sale price?=$210
Step-by-step explanation:
$280 =100%
$x =25%
$280 x 25%=7000/100=<u>70</u>
<u>280-70=210</u>
If x=4 , then . . .
... 7x = 28
... 7x+4 = 28+4 = 32
... absolute value of 32 is 32.
... -(absolute value of 32) = -32
Answer:
x=29
Step-by-step explanation:
(x+3)+(x-1)+(x+1)=90
x+3+x-1+x+1=90
3x+3=90
3x=90-3
x=87/3
x=29
x+3=32
x+1=30
x-1=28
Checking
(x+3)+(x-1)+(x+1)=90
(29+3)+(29-1)+(29+1)=90
32+28+30=90
90=90
