Simple interest to find the ending balance $460 at 13% for 2 years

Komok [63]

Answer:

$568.16

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 13%/100 = 0.13 per year,

then, solving our equation

I = 416 × 0.13 × 2 = 108.16

I = $ 108.16

The simple interest accumulated

on a principal of $ 416.00

at a rate of 13% per year

for 2 years is $ 108.16.

Using the slope formula, if y = -46, slope is 6, and the y-intercept is -13, solve for x. Slope formula: y = mx + b (Note: Only

hram777 [196]

Answer:

x = - $\frac{11}{2}$

Step-by-step explanation:

rearrange the formula, giving x in terms of b, y and m

given y = mx + b ( subtract b from both sides )

mx = y - b ( divide both sides by m )

x = $\frac{y-b}{m}$

evaluate using y = - 46, m = 6 and b = - 13

x = $\frac{-46-(-13)}{6}$ = $\frac{-33}{6}$ = - $\frac{11}{2}$

Write an equation for each situation and then solve your equation.

motikmotik

Answer:

Q1. 20x = 200. The value of x is 10

Q2. 7 - 3x = 1. The value of x is 2.

Step-by-step explanation:

In order to find an equation, you have to let the number be any variable, such as m or n or z. So I will let the number be x variable. Then the question says a number is multiplied by 20 is equals to 200 :

Let number = x,

$x \times 20 = 200$

$20x = 200$

$20x \div 20 = 200 \div 20$

$x = 10$

Same for the next question. Given that a number multiplied by 3 :

Let number = x,

$x \times 3 = 3x$

Then subtracted by 7 equals to 1 :

$7 - 3x = 1$

$7 - 3x - 7 = 1 - 7$

$- 3x = - 6$

$- 3x \div - 3 = - 6 \div - 3$

$x = 2$
