Answer:
1/3
Step-by-step explanation:
let a = adults
so then 2a = children
a/2a(+a) = a/3a
Answer:
3 1/2 cups of flour
Step-by-step explanation:
I used this equation:
2.5/5 = x/7
Then I cross multiplied:
2.5 * 7 = 5x
After I found out that x = 3 1/2
To calculate the mean, you must add all the numbers together and then divide by the total amount of numbers there are.
The mean score of all these numbers would be 80.875, or 80 rounded to the nearest hundredth.
You can see a definite downward trend as variable x increases. Were you to draw a straight line with neg. slope thru these points, trying to keep the line centered among the points, you'll find that the change in y is roughly -6 when x increases by 8. That gives us the rough slope of -6/8, or -3/4, or -0.75.
Which of the given 2 negative slopes is closer to -0.75?
Answer:
x=9 x=-1
Step-by-step explanation:
2(x-4)^2=50
Divide each side by 2
2/2(x-4)^2=50/2
(x-4)^2=25
Take the square root of each side
sqrt((x-4)^2)=sqrt(25)
x-4 = ±5
x-4 =5 x-4 = -5
Add 4 to each side
x-4+4=5+4 x-4+4 = -5+4
