Double number line, you draw one number line on top of each other. Since you only have 2/3 out of a whole, you only need 1 number line. So separate 2/3 into 4 pieces and you get your answer.
Answer:
-3 I think
Step-by-step explanation:
well 10-7=3 and 13-10=3
but since it is greater number first it would make it a -3
(8 min) x ( day/1,440 min) x (20 /day) x (365 da/yr) x (35 yr) =
(8 x 20 x 365 x 35) / (1,440) days =
(2,044,000) / (1,440) days =
1,419-4/9 days = 3.89 years
Rounded to the nearest year: <em>4 years</em>
At a pack a day for 35years, I would have expected more than
4 years' damage. But I've checked my math and haven't found
the mistake, so I'll let that be my answer.
Yes, it does.
HEHE btw what is that haha i know
Answer:
xy = 1
k = 79
Step-by-step explanation:
Question One
The first and third frames look to me to be the same. I'll treat them that way.
y = x^2 Equate y = x^2 to the result of 2y + 6 = 2x + 6
2y + 6 = 2(x + 3) Remove the brackets
2y + 6 = 2x + 6 Subtract 6 from both sides
2y = 2x Divide by 2
y = x
Now solve these two equations.
so x^2 = x
x > 0
1 solution is x = 0 from which y = 0. This won't work. x must be greater than 0. So the other is
x(x) = x Divide both sides by x
x = 1
y = x^2 Put x = 1 into x^2
y = 1^2 Solve
y = 1
The second solution is
(1,1)
xy = 1*1
xy = 1
Answer: A
Question Two
square root(k + 2) - x = 0
Subtract x from both sides
sqrt(k + 2) = x Square both sides
k + 2 = x^2 Let x = 9
k + 2 = 9^2 Square 9
k + 2 = 81
k = 81 - 2
k = 79
