If you divide 5 over 3 you get the decimal 1.6, not 15.
the
correct answer would be 45. how do i get that? read below.
________________________________
to solve:
1.multiply each side by 3, to get the 3 on the left side to cancel out. so you get x = 15 times 3.
2. 15 * 3 =
45
Answer:
You make $32,000 a year and want to save 10% of your income every year. How much should you put into savings every month?
$32$,000 x 0.10 = 3,200
You want to save $3200 a year.
You should be saving $266.67 a month or $133.33 a paycheck if you are paid
Step-by-step explanation:
5^2 = 25
13^2 = 169
169 - 25 = 144
The square root of 144 = 12.
12 + 2 = 14.
a^2 + b^2 = c^2
5^2 + b^2 = 13^2
25 + b^2 = 169
-25 -25
b^2 = 144
sqrt sqrt
b = 12
+2
14
Let the cost of jacket before sales tax be z.
sales tax = $2.38
When the sales tax was included the jacket = $37
Cost of Jacket + Sales tax = 37
z + 2.38 = 37 Equation
z = 37 - 2.38
z = 34.62
Hence cost of jacket = $34.62
Hope this explains it.

This problem involves Newton's 2nd Law which is: ∑F = ma, we have that the acting forces on the mass-spring system are: that correspond to the force of resistance on the mass by the action of the spring and that is an external force with unknown direction (that does not specify in the enounce).
For determinate we can use Hooke's Law given by the formula where correspond to the elastic constant of the spring and correspond to the relative displacement of the mass-spring system with respect of his rest state.
We know from the problem that an 15 Kg mass stretches the spring 1/3 m so we apply Hooke's law and obtain that...
Now we apply Newton's 2nd Law and obtaint that...
± =
Finally... ±
We know from the problem that there's not initial displacement and initial velocity, so... and
Finally the Initial Value Problem that models the situation describe by the problem is
