These are vertical angles, meaning they're always the same length.

$3x = x + 28$

$2x = 28$

$x = 14$

If $1600 earned simple interest of $56.24 in 2 months, what was the simple interest rate? The simple interest rate is % (Do not

Fiesta28 [93]

Answer:

$\$21.1$

Step-by-step explanation:

We know that for principal amount P , time period T and rate of interest $R\%$ , simple interest is given by $S.I. = \frac{P\times R\times T}{100}$ .

Here ,

$P=\$1600\\T=2\,\,months=\frac{2}{12}\,\,years=\frac{1}{6}\,\,years\\S.I=\$56.24$

To find : simple interest rate i.e., $R\%$

On putting values of $P\,,\,T\,,\,S.I$ in formula , we get $S.I. = \frac{P\times R\times T}{100}$

$56.24 = \frac{1600\times R\times 1}{600}\\R=\frac{56.24\times 600 }{1600}=\frac{703\times 3}{100}=\$21.09$

Now we need to round off the answer to the nearest tenth .

So, simple interest rate is % = $\$21.09$ = $\$21.1$

1/8(p+24)=9<br> Distributive property

Grace [21]

Hey there!

1/8(p + 24) = 9

1/8(p) + 1/8(24) = 9

1/8p + 3 = 9

SUBTRACT 3 to BOTH SIDES

1/8p + 3 - 3 = 9 - 3

CANCEL out: 3 - 3 because it gives 0

KEEP: 9 - 3 because it help solve for the p-value.

NEW EQUATION: 1/8p = 9 - 3
SIMPLIFY IT!

1/8p = 6

MULTIPLY 8 to BOTH SIDES

1/8p * 8 = 6 * 8

CANCEL out: 1/8 * 8 because it gives 1

KEEP: 6 * 8 because it gives the p-value.

NEW EQUATION: p = 6 * 8

SIMPLIFY IT!

p = 48

Therefore, your answer is: p = 48

Good luck on your assignment & enjoy your day!

Thirty percent of Irma’s Boutique’s sales came from leggings. They sold $390 worth of leggings last week. What were the total sa

RUDIKE [14]

Answer:

The total sales of Boutique last week = $1300

Step-by-step explanation:

Given that:

Percent of sales came from leggings = 30%

Worth of leggings sold = $390

Let,

x be the total sales in the week.

30% of x = 390

$\frac{30}{100}x=390$

0.3x = 390

Dividing both sides by 0.3

$\frac{0.3x}{0.3}=\frac{390}{0.3}\\x=1300$

Hence,

The total sales of Boutique last week = $1300
