Do 4007 x 0. 25 on a calculator
Answer:
the answer would closer to 750 so no
Step-by-step explanation:
Because he has 735 left hope this helps
It means the check has not been presented for payment , the check hasn't been cashed or deposited
So... the radiator has 15 liters of 70% antifreeze.. but needs an 80% antifreeze
well, so, you need to drain some and put some with higher percentage, seems to be, you will end up at the same 15 liters, possible the radiator's capacity, of 80% antifreeze
so, the same amount going out, of 70% is the same amount going in, of 100% antifreeze
now.. let's use the decimal format for the percents, or 70% is 70/100 or 0.7 and so on

so.. let's subtract, from the current solution, 0.7x and add 1x or x, our antifreeze concentration amount, should be 12 though
10.5 - 0.7x + x = 12
solve for "x"
Y=-3x+23
distribute -3, get y alone (add 2 to both sides)
