Answer:
5x^2 - 7x - 10.
Step-by-step explanation:
11x^2+2-7x-6x^2-12
Bring like terms together We get:
11x^2 - 6x^2 - 7x + 2 - 12
= 5x^2 - 7x - 10.
2:3:9......added together = 14
2/14 (500) = 1000/14 = 71.43
3/14 (500) = 1500/14 = 107.14
9/14 (500) = 4500/14 = 321.43
Answer:
x=-7
Step-by-step explanation:
Answer:
BK=39/7
Step-by-step explanation:
because NQZ~CBK
so BK/QZ = TZ/KF
(4x+1)/(2x+7) = 27/45 = 3/5
5(4x+1) = 3(2x+7)
20x + 5 = 6x + 21
14x = 16
x = 8/7
=> BK = 4(8/7)+1 = 39/7
The answer for rounding 17.55 to a decimal place is 88/5.
