Hello :

5a-5 +2a =2a
5a =5
a=1 ( refused)
conclusion : <span>none</span>
3. 140 m^3
(3 x 6 x 7) + (1 x 2 x 7) = 126 + 14 = 140
4. 216 in^3
(4 x 4 x 9) + (3 x 4 x 6) = 144 + 72 = 216
An item that costs $30, when discounted 15 percent, will cost $25.5. The easiest way of calculating discount is, in this case, to multiply the normal price $30 by 15 then divide it by one hundred. So, the discount is equal to $4.5. To calculate the sales price, simply deduct the discount of $4.5 from the original price $30 then get $25.5 as the sales price.
