Answer:

Simplifying

3y + 13 = 2y + 25

Reorder the terms:

13 + 3y = 2y + 25

Reorder the terms:

13 + 3y = 25 + 2y

Solving

13 + 3y = 25 + 2y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.

13 + 3y + -2y = 25 + 2y + -2y

Combine like terms: 3y + -2y = 1y

13 + 1y = 25 + 2y + -2y

Combine like terms: 2y + -2y = 0

13 + 1y = 25 + 0

13 + 1y = 25

Add '-13' to each side of the equation.

13 + -13 + 1y = 25 + -13

Combine like terms: 13 + -13 = 0

0 + 1y = 25 + -13

1y = 25 + -13

Combine like terms: 25 + -13 = 12

1y = 12

Divide each side by '1'.

y = 12

Simplifying

y = 12

marysya [2.9K]

Answer:

Interes ganado= €59.07

Step-by-step explanation:

Dada la siguiente informacion:

300€ durante 5 años al 0.3% de interés compuesto mensual.

Para calcular el valor final de la inversión y el interés ganado, debemos usar la siguiente formula:

FV= PV*(1 + i)^n

Present Value= 300

i= 0.003

n= 5*12= 60 meses

FV= 300*(1.003^60)

FV= 359.07

Interes ganado= 359.07 - 300

Interes ganado= 59.07

Sold the equation. Round to the nearest hundredth. 17 · <img src="https://tex.z-dn.net/?f=1.8%5E%7B-x%2B7%7D%20%3D%205"

svetlana [45]

Answer:

Final answer is approx x=4.26.

Step-by-step explanation:

Given equation is $1.8^{-x+7} = 5$

Now we need to solve equation $1.8^{-x+7} = 5$ and round to the nearest hundredth.

$1.8^{-x+7} = 5$

$\log(1.8^{-x+7}) = \log(5)$

$(-x+7)\log(1.8) = \log(5)$

$(-x+7) = \frac{\log(5)}{\log(1.8)}$

$(-x+7) = \frac{0.698970004336}{0.255272505103}$

$-x+7 = 2.73813274192$

$-x = 2.73813274192-7$

$-x =−4.26186725808$

$x =4.26186725808$

Round to the nearest hundredth.

Hence final answer is approx x=4.26.

Big Ben (the clocktower) in London has a circumference of 72.22 feet and an area of 415.27 feet^2. What is the diameter AND radi

Mashutka [201]

Answer:

Diameter = 23 Radius = 11.5

Step-by-step explanation:

Divide the circumference by π, or 3.14 for an estimation. The result is the circle's diameter.

72.22 ÷ 3.24 = 23

diameter = 23

Divide the diameter by 2.

23 ÷ 2 = 11.5

There you go, you found the circle's radius
