Answer: x=27
Step-by-step explanation:
3x-4(4)=65
3x-16=65
3x=65+16
3x=81
3x/3=81/3
X=27
Answer:
pounds
Step-by-step explanation:
Each person will eat 1/3 pound of chicken, and there are 8 people. So, we want eight 1/3 pounds. We can write this as an addition problem:
1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3
This addition problem is equivalent to the multiplication problem: 8 * (1/3)
Both will yield the same result: 8/3 pounds =
pounds, and that's the answer.
Hope that helps!
4 x^2 + 28 x + 49 = 0
Divide both sides by 4:
x^2 + 7 x + 49/4 = 0
Write the left hand side as a square:
(x + 7/2)^2 = 0
Take the square root of both sides:
x + 7/2 = 0
Subtract 7/2 from both sides:
Answer: x = -7/2
