2x+2y= 24 x=3y What is the value of x+y? I WILL MARK BRAINLIEST AND GIVE 20 POINTS.

1 answer:

3 0

Since this is a system of equations, substitute the value of x into the other equation.

2(3y)+2y=24
6y+2y=24
8y=24
y=3

x=3(3)
x=9

To check my work, substitute my x and y values:
2(9)+2(3)=24
18+6=24
24=24

Your answer is (3,9)

Hope this helps! Have a wonderful day :)

The value of a car after t years can be found using the formula V = C(1 - r)t, where V is the current value of the car, C is the

Stells [14]

The given formula is
$V = C(1-r)^{t}$

Therefore
$(1-r)^{t} = \frac{V}{C} \\\\ 1-r = ( \frac{V}{C} )^{1/t} \\\\ r = 1 - ( \frac{V}{C} )^{1/t}$

Given:
C = $25,000
V = $12,000
t = 4.5 years

C/V = 0.48
1/t = 0.2222
Therefore
$r = 1 - 0.48^{0.2222} = 0.1505 = 15.05\%$
