2 * 200 * 300 = 200 + x * 300 + x = (200 + 300) * x
Solve for x.
Answer:
D. 5y^2 - 4y - 1
Step-by-step explanation:
Combine like terms:
(y^2 -y +1) +(4y^2 -3y -2)
= y^2(1 +4) +y(-1-3) +(1 -2)
= 5y^2 -4y -1
Steps:
1. Do a proportion
X/799.45 times 15/100
2. Do 15 times 799.45 which equals 11,991.75
3. Divide 11,991.75 by 100
4. 119. 91 is the price being taken off
5. Do 799.45 minus 119.91
6. Your answer is
$679.54
Answer: Your answer should be 12:23
Step-by-step explanation: on the clock the time is 2:25. You simply subtract 2:48 and 2:25. 48-25=23 and the twos cancel out but instead of putting zero you put 12 since your going backwards two on the clock. Hope it helps!!!
