The overall ionic formula for a compound must be electrically neutral, meaning it has no charge. When writing the formula for the ionic compound, the cation comes first, followed by the anion, both with numeric subscripts to indicate the number of atoms of each.

Corresponding sides of the two triangles occur in a ratio with one another. In particular, you have the relationship

$\dfrac6{6+x}=\dfrac{10}{15}=\dfrac y{y+4}$

We only need the first two parts to solve for $x$ :

$\dfrac6{6+x}=\dfrac{10}{15}\implies6\cdot15=10(6+x)\implies90=60+10x\implies30=10x$

$\implies\boxed{x=3}$

P=$4000.00,A=$5300.00,t=5 years

Answer:

The rate of Simple Interest is 6.5 %

Step-by-step explanation:

Given as :

Principal = $ 4000.00

Amount = $ 5300.00

The time period of loan = 5 years

Let The rate of simple interest = R

Now,

From Simple Interest method

Simple Interest = $\frac{Principal\times Rate\times Time}{100}$

And , Simple Interest = Amount - Principal

So , Simple Interest = $ 5300.00 - $ 4000.00

Or, Simple Interest = $ 1300

Now, Simple Interest = $\frac{Principal\times Rate\times Time}{100}$

So, $ 1300 = $\frac{ 4000\times Rate\times 5}{100}$

Or, $ 1300 × 100 = $ 4000 × Rate × 5

Or, Rate = $\frac{1300\times 100}{4000\times 5}$

Or, Rate = 6.5

Hence The rate of Simple Interest is 6.5 % Answer

Three times the sum of a number and 4 is 8 less than one-half the number. Write and solve an equation to find the number.

Dahasolnce [82]

3(x+4)=1/2x-8 that's your original equation. If you read through the problem as you look at my work, you will see it matches up as you read it out loud and see my equation.
to solve, first distribute.
3x+12=1/2x-8
next you need to subtract 1/2x from both sides. this is using the identity property of addition.
2.5x+12=-8
next, subtract 12 from both sides. this demonstrates the identity property of subtraction.
2.5x=-20
next, divide by the coefficient of x (which is 2.5) to find the value of x, your variable.
x=8. you're done. hope this helped :)
