After 3 months, $3,900 deposited in a savings account with simple interest had grown to a total of $4,017. What was the interest

chathamtownfc.net:

12%

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 12%/100 = 0.12 per year,

then, solving our equation

I = 3900 × 0.12 × 0.25 = 117

I = $ 117.00

The simple interest accumulated

on a principal of $ 3,900.00

at a rate of 12% per year

for 0.25 years is $ 117.00.

A triangle is a three-sided polygon. The sum of angles in a triangle is 180 degrees.

Types of triangles

An equilateral triangle : the three sides are equal in length.An isosceles triangle : two sides are equal in length A right angled triangle : an angle measures 90 degrees

The perimeter of a triangle is (8t -7 + u) centimeters

The perimeter of a triangle is the sum of the three lengths of the triangle

2t +2 + 6t - 7 + u -2

Combine similar terms

(2t + 6t) + (2 - 7 - 2) + u

Add combined similar terms

8t -7 + u

Value of

*

Step-by-step explanation:

Given that:

*

Solve for x;

Taking LCM of a , b and x is abx.

*

Multiply both sides by abx we get;

*

Subtract ab from both sides we get;

1-ab = bx + ax

Using distributive property:

*

1- ab = x(a + b)

Divide both sides by a+b we get;

*

Therefore, value of x is;

*

Can you please help me with that

see explanation

Step-by-step explanation:

1

4x = 3x + 5 ( subtract 3x from both sides )

x = 5

2

7m = 8 + 5m ( subtract 5m from both sides )

2m = 8 ( divide both sides by 2 )

m = 4

3

2a = 9 - a ( add a to both sides )

3a = 9 ( divide both sides by 3 )

a = 3

4

*
d = 3 ( multiply both sides by 4 to clear the fraction )

d = 3 × 4 = 12

5

5y + 6 = 21 ( subtract 6 from both sides )

5y = 15 ( divide both sides by 5 )

y = 3

6

2n - 3 = 6 ( add 3 to both sides )

2n = 9 ( divide both sides by 2 )

n = 4.5

Help Pls I need the chathamtownfc.net quick
liubo4ka <24>

chathamtownfc.net:

That"s correct

Step-by-step explanation:

In math, we define a quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic is y = ax^2 + bx + c, where a, b, and c are numbers and a cannot be 0. Examples of quadratic equations include all of these: y = x^2 + 3x + 1. y = x^2.
