Answer:
7x²-12x-10
Step-by-step explanation:
(5x²-8x+1) + (2x²-4x-11)
combine like terms
7x²-12x-10
Answer:
5x+4=9
Step-by-step explanation:
Simply just divide 5 and 3/5:
5/(3/5)=25/3
Therefore, 5 cups of birdseeds will last 25/3 days.
J Multiply the first equation by 3
F Add the two equations and solve for x
G x = -3
B Substitute the value of x in the first equation, y = 1
C the solution is (-3, 1)
Hi,
Start with 6b-27=3(5b-2)
then add 27 to each side, 6b-27+27=15b-6+27
next simplify, 6b=15b+21
now subtract 15b from both sides, 6b-15b=15b+21-15b
simplify again, -9b=21
divide both sides by -9, -9b/-9 = 21/-9
answer: -7/3
Have a great day!
