3x+4=-5x-3+15, what are some of the steps that should be taken to solve for x? Select all that apply.

3x+4=-5x-3+15
First combine like terms:
3x+4=-5x+12
Get x on one side:
3x+4=-5x+12
-3x -3x
4=-8x+12
Next get x by itself:
4=8x+12
-12 -12
-8=8x
Now divide one more time to get x by itself since 8x is 8 times x and we must do the opposite (÷).
-8/8=8x/8
-1=x ---> x=1

Suppose the number of students in one of the classes is :

$x$

So ;

$Mr.Lopez \: \: had \: \: \frac{92.5}{100}x \\$

_________________________________

$Mrs.Foster \: \: had \: \: \frac{19}{20} x \\$

So :

$Mrs.Foster \: \: had \: \: \frac{19 \times 5}{20 \times 5} x \\$

$Mrs.Foster \: \: had \: \: \frac{95}{100}x \\$

$Ms.Kelly \: \: had \: \: 0.9x$

$Ms.Kelly \: \: had \: \: \frac{9}{10} x \\$

$Ms.Kelly \: \: had \: \: \frac{90}{100} x \\$

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Compare :

$\frac{95}{100} x > \frac{92.5}{100} x > \frac{90}{100} x \\$

Thus :

$Mrs.Foster’s \: \: class \: > \: Mr.Lopez’s \: \: class \: > \: Ms.Kelly’s \: \: class \\$

Mrs. Emily Francis saves RM10 000 in a bank . by the end of the eighth year , the money collected amounts to RM19 992.71.if the

Anna11 [10]

Answer:

8.85% per year

Step-by-step explanation:

To find the interest rate of a compounding interest, we use the formula:

$r=n[(\dfrac{A}{P})^{\dfrac{1}{nt}}-1]$

Before we start solving, let's break down all the variables that we have.

A = 19,992.71

P = 10,000.00

n = 2

t = 8

r = ?

Now let's put the values into the formula.

$r=2[(\dfrac{19,992.71}{10,000.00})^{\dfrac{1}{2(8)}}-1]$

$r=2[(\dfrac{19,992.71}{10,000.00})^{\dfrac{1}{16}}-1]$

$r=2[(\dfrac{19,992.71}{10,000.00})^{0.0625}-1]$

$r=2[(1.9992.1)^{0.0625}-1]$

$r=2[1.0442499885-1]$

$r=2[0.0442499885]$

$r=0.08849997699$ or $8.85%$

So the rate the Mrs. Emily Francis got from the bank was 8.85% per year.
