Answer:
7,12.2
Step-by-step explanation:
100+49=149
√149≈12.2
x^2+49=100
x^2=51
=7
-3x = 21
Divide -3 from both sides and you get x = -7
1/3x = 6
Divide 1/3 from both sides and you get x = 18
-1/2x = -7
Divide -1/2 from both sides and you get x = 14 (you get a positive answer from 2 negatives)
Dividing 1/3 is just multiplying by 3, and dividing -1/2 is just multiplying by -2
Answer:
A.) $2.52 less per pound. B.) $13.08 more
Step-by-step explanation:
A.) You pay $14.82 for 1.5 lbs of ham. You divide $14.82 by 1.5 lbs (14.82/1.5) to figure out how much you spend per pound of ham. You should get $9.88. Since you spend $12.40 per pound of roast beef, you subtract $9.88 from $12.40 ($12.40 - $9.88). You should get $2.52, which is your answer.
B.) Since you paid $14.82 for 1.5 lbs of ham, you already have this variable. Take the 2.25 lbs of roast beef and multiply it by $12.40 per pound (12.40*2.25). You then take that number ($27.90) and subtract it by $14.82 (27.90-14.82) and you should get your answer, $13.08.
Steps:
1) 4,000 * .045 = 180
2) 180 * 6 = 1,080
3) 4,000 + 1,080 = 5,080
4)4,000 * .049 = 196
5) 196 * 6 = 1,176
6) 4,000 + 1,176 = 5,176
7) 5,176 - 5,080 = $96
Answer= $96
