Answer:

x =17.6

The three angles are

6x = 105.6

x-3 =14.6

3x+7 = 59.8

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

6x + x-3 + 3x+7 = 180

Combine like terms

10x +4 = 180

Subtract 4 from each side

10x+4-4= 180-4

10x = 176

Divide each side by 10

10x/10 =176/10

x =17.6

The three angles are

6x = 6*17.6= 105.6

x-3 = 17.6-3 =14.6

and 3x+7 = 3(17.6)+7 =52.8+7 = 59.8

What single decimal multiplier would you use to increase by 5% followed by a 20% increase?

sashaice [31]

Answer:

The single decimal multiplier is 1.26.

Step-by-step explanation:

Multipliers:

For a decrease of a%, we multiply by: $\frac{100-a}{100}$

For a increase of a%, we multiply by: $\frac{100+a}{100}$

For consecutive changes, we multiply the multipliers.

Increase of 5%

Multiply by $\frac{100+5}{100} = \frac{105}{100} = 1.05$

Increase of 20%

Multiply by $\frac{100+20}{100} = \frac{120}{100} = 1.2$

Consecutive:

1.05*1.2 = 1.26

The single decimal multiplier is 1.26.

hram777 [196]

Answer:

y = 3·2^x

Step-by-step explanation:

At x=0, f(0) = a = 3

At x=1, f(1) = a·b = 3b = 6 ⇒ b = 6/3 = 2

So, the function is ...

f(x) = 3·2^x
