Simplify: ? (10x = 105 - (12x – 247)

Greeley [361]

Answer:

x = 16

Step-by-step explanation:

10x = 105 - (12x - 247) //Distribute - sign

10x = 105 - 12x + 247 // Add 12x & combine like terms

10x + 12x = 352

22x = 352 //Divide 22

x = 352/22

x = 16

1.) how much will $5000 be worth in 5 years if it is compounded continuously at 3% interest.

Nady [450]

Answer:

$5809.17

$6149.01

$2211.72

Step-by-step explanation:

Continous interest formula:

(pv)e^(rt)

we have

5000e^(5*.03)= 5809.17

Same equation from before

2500e^(.09*10)= 6149.01

2000e^(.0575*(21/12))

(we write 21/12 because that's how many years has passed)

= 2211.72

Use the scale drawing and the scale factor to enlarge a square that has a side length of 12 in. Scale factor= 3 in:2m.

podryga [215]

Given:

The side of square = 12 in.

Scale factor of enlargement = 3 in : 2 m

To find:

The proportion that is use to solve the side length, x, of the enlarged square.

Solution:

Let, the side of length of enlarged square = x m

In case of enlargement the corresponding sides are proportional.

$\dfrac{3}{12}=\dfrac{2}{x}$

$3x=2\times 12$

$3x=24$

Divide both sides by 3.

$x=\dfrac{24}{3}$

$x=8$

Therefore, the required proportion is $\dfrac{3}{12}=\dfrac{2}{x}$ and the side length of the square after enlargement is 8 m.
