Answer:
7 miles per minute!
Step-by-step explanation:
To find the unit rate you need to have a denominator of one, and with the info you have your fraction looks like this--->35/5
How to solve: 35/5 = x/1
You get from 5 to 1 by dividing by 5, so to find x you have to divide 35 by 5, and you get 7!
So replace x with 7 and your answer will be 7 miles per minute!
I hope this helps, and have a great day!
Answer:
5
Step-by-step explanation:
For the point to be a solution to the equation, it has to lie on the line 5x -2y= 30 and therefore must satisfy the equation.
5x -2y= 30
When x=8,
5(8) -2y= 30
40 -2y= 30
40 -30= 2y (bring constant to 1 side)
2y= 10 (simplify)
y= 10 ÷2
y=5
Thus the missing value is 5.
Answer:
About 219.15% (if you were asked to round to nearest hundredths of a percent).
Step-by-step explanation:
The percent change can be found by calculating:
So the answer is approximately 219.1489%.
Answer: 40 inches
Step-by-step explanation:
The woman weight and the seat will be: 145lb + 5lb = 150lb,
her son weight and the seat will be: 95lb + 5lb = 100lb
her daughter weight and the seat will be: 70lb + 5lb = 75lb
Given that the woman is on the left side of the seesaw, 60 inches from the fulcrum. The moment of the woman will be 150 × 60 = 9000
The daughter and son both get on the right side.
If the son sits 60 inches from the fulcrum, his moment will be:
100 × 60 = 6000
The sum of the moment of the son and daughter must be equal to the moment of their mother.
Let the position of the daughter = X
The moment of the daughter will be:
75 × X = 75X
Equate the moment of the mother to the sum of the moment of her children
9000 = 6000 + 75X
Collect the like terms
75X = 9000 - 6000
75X = 3000
X = 3000/75
X = 40
The position the daughter should sit to balance the seesaw is 40 inches away from seasaw to the right.
2(6x+y)=24. i hope this helps
