Answer:
The equation is
15x = 610
Step-by-step explanation:
A dime is 10 cents while a nickel is 5 cents
$6.10 is same as 610 cents
Let the number of dimes and number of nickels be x
10x + 5x = 610
15x = 610
Answer:
x is less than or equal to negative 14.
Step-by-step explanation:
so for now we should pretend that the greater than or equal to is an equal sign, and simplify the problem to get x alone on a side
remove 5 from each side
-x/3=1/3-5
-x/3=14/3
multiply both sides by 3
-x=14
x=-14
so we can now replace the equal sign with the equal or greater to, so x is less than or equal to -14
I would say the last one is B, because of you use a calculator you will see that the equation adds up to B. Also if you have any trouble with your math download the app Photomath. It changed my life! Hope this helps
Answer:
The value of the maximum distance the spring will be compressed
x = 0.143 m= 14.3 cm
Step-by-step explanation:
Given data
Mass m = 1.5 kg
h = 0.9 m
k = 1500
Since the book is released from a height h = 0.9 m above the top of the spring. so the total distance
y = h + x
Now in that case for the spring
By rearranging the above equation we get
Put all the values in above equation we get
By solving the above equation we get
x = 0.143 m= 14.3 cm
This is the value of the maximum distance the spring will be compressed.
