(−7c+8d)0.6 distributive property

Ksivusya [100]

We are given

$(-7c+8d)0.6$

we can use distribute property

Distributive property:

$(A+B)C=A*C+B*C$

so, we can write it as

$(-7c+8d)0.6=-7c*0.6+8d*0.6$

$(-7c+8d)0.6=-7*0.6c+8*0.6d$

now, we can multiply terms

and we get

$(-7c+8d)0.6=-4.2c+4.8d$ ..............Answer

The number 66 is increased to 72. What is the percentage by which the number was increased, to the nearest tenth of a percent?

Lunna [17]

Answer:

The increase is 9.1%

Step-by-step explanation:

Step 1: Make an equation

$66 * x = 72$

$66x = 72$

Step 2: Divide both sides by 66

$66x / 66 = 72 / 66$

$x = 1.09090$

Step 3: Find the increased

$1 - 1.09090$

$0.091 * 100$

9.1%

Answer: The increase is 9.1%
