2x-1=6 so 2x=7 x=3.5
3.5^2 = 12.25 x 4 = 49-1 = 48
Where’s the answers ?
Step-by-step explanation:
Answer:
x - 2 => x = 2
x² + 3ax - 2a
=> 2² + 3 × a × 2 - 2 × a
=> 4 + 6a - 2a
=> 4 + 4a
=> 4 ( 1 + a )
★ 1 + a = 0
a = -1
You have to add the 2 yards together... 5,215 + 1,850 = 7,065. If 2 bags will cover 2,500 square feet, then 1 bag will cover 1,250. Divide 7,065 by 1,250 and you will need 6 bags of seed. For problem 2, add all the purchases together, which will be $250.50. This will get him a 30% discount. So his total price after the discount will be about $175.35. For problem 3, this is an exponential function. The $10,000 loan with 9% rate over 5 years is equal to 10,000(1+0.09)^5 which is about $15,500, so he will have to pay an additional $5,500.
$2 / 0.3 = $6.67
Check:
$6.67 * 0.3 = $2 :)
