If i put $1500 into my savings account and earned $180 of interest at 4% simple interest, how long was my money in the bank
Answers
The percent of interest you earned is (180/1500) = 0.12 = 12% .
Since you got 4% per year, your money was in the bank for
(12 %) x (1 year / 4%)
= (12 x 1 / 4) (% / %) (year) = 3 years .

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the value of addition of both equations be = C
Let the first equation be represented as = A
The value of A is
5x - 9y = 1 be equation (1)
Let the second equation be represented as = B
The value of B is
-7x + 2y = -5 be equation (2)
Now , the addition of equation (1) + equation (2) is
The value of C is = equation (1) + equation (2)
The value of C is 5x - 9y = 1 + -7x + 2y = -5
5x + ( -7x ) = -2x
-9y + 2y = -7y
1 + ( -5 ) = -4
Therefore , the equation is -2x - 7y = -4
Hence , the solution of equation C is -2x - 7y = -4

Answer:
Solution = -2x-7y=-4
Step-by-step explanation:
Add the x-component to the x-component, add the y-component to the y-component, add the number to the number.
It looks like this
5x + (-7x) = -2x
9y + (-2y) = -7y
1 + (-5) = -4
Then, put the solutions in the places where you see them in the equation, x goes first, y comes second, then this equals the number value.
-2x - 7y = -4

The perimeter is the side lengths added together.
P = s + s + s + s
P = 4s
217 = 4s
Divide by 4 to find the length of one side.

1). Recall the formula for the volume of a cylinder:
Volume = (pi) x (radius of the round end)² x (length or height) .
2). Gather together the number you'll use for pi, the radius of the
cylinder's round end, and its length or height. Make sure that the
radius of the round end and the length or height are in the same units.
If they're not, then convert something so that they are.
3). Write each number into its place in the formula.
4). Perform the indicated operations. The final number is the
volume of your cylinder.
h= height
you square the radius and then multiply by the
