Answer:
y+3 = -6(x+9)
Step-by-step explanation:
m(x-x1)= (y-y1)
-6[x-(-9)] = [y-(-3)]
-6(x+9) = y+3
.....
5x=39 x stands for the age of bob so 39/5 =7.8 which is rounded up to 8 and if you multiply 8 by 5 you get 40 but if you multiply 7.8 by 5 you get 39 so his age would be 7.8 years old.
Answer:
You would use V=3 times 5 times 4
First you would multipy 5 times 4 then when you get that answer you would multiply the 3.
Answer:
No its not true
Step-by-step explanation:
(7x2)-5= 14-5= 9
(2x2)+8= 4+8= 12
9=12
The full price is $82, (100%), the discounted price is $65.60, (?%)
So lets see something:
$82 ------------- 100%
$65.60 --------------- x%
Multiply in cross
82.x = 65,60 . 100
82x = 6560
Divide both sides by 82
82x/82 = 6560/82
x = 80
So the discounted price is equal to 80% of the initial price
100% - 80% = 20% so the discount is 20%
