Lowe’s would be a better. They would be $10 cheaper even after the delivery fee.
5/2 is the answer.
Have a nive day!
28 - 2.2x = 11.6x - 54.8
28 + 54.8 = 11.6x + 2.2x
82.8 = 13.8x
82.8 / 13.8 = x
6 = x
or x = 6
Answer:
x = approx. 1.24 or -7.24
Step-by-step explanation:
It's hard to factor directly so we should use the quadratic formula or complete the square. I'm going to go with completing the square.
x²+6x-9=0
x²+6x=9
x²+6x is the same as x²+2·3·x, in order to make this into the algebraic identity (A+B)²=A²+2AB+B², we must add B², or in this case 3² to both sides. (A is x, B is 3)
x²+6x+9=18
(x+3)²= 18
x+3= ±√18
x= ±4.24 -3 (approximately 4.24)
First solution for x = 4.24-3 = 1.24
Second solution for x = -4.24-3 = -7.24
Hey there!
10(a - 2.5 + 0.56b)
= 10(a) + 10(-2.5) + 10(0.56b)
= 10a - 25 + 5.6b
= 10a + 5.6b - 25
Therefore, your answer is: 10a + 5.6b - 25
Good luck on your assignment and enjoy your day!
