Answer:
1 skateboard will cost $73 and the other will cost $72
Step-by-step explanation:
Skateboard A (Original) = X
Skateboard B (+$1) = X + 1
Solving for X
(x + 1) + x = 145
2x + 1 - 1 = 145 - 1
2x = 144
2/2 = x
144/2 = 72
x = 72
-x(3+4)
If you distribute it to all the numbers the simplest form would be -3x-4x
This would equal about 23,900
i hope this helps you.
Now we have to,
find the required value of x.
Let's begin,
→ 3x-2 = 2(x-5)
→ 3x-2 = 2x-10
→ 3x-2x = -10+2
→ x = -8
Hence, value of x is -8.
Answer:
Step-by-step explanation:
we calculate how much 0.3% is from 3280
y=3280*0.3/100=9.84$
months in 9y
12*9=108
the interest of 9y
108y=1062.72$
the sum of interest + the money borrowed
1062.72+3280=4342.72$
