1. Which two properties are needed to solve the equation 8.5d + 7.5 = 100 + 3? Distributive property and division property of equality

Subtraction property of equality and division property of equality

Distributive property and collecting like terms property

Addition property of equality and division property of equality

Step-by-step explanation:

Given equation:

Step 1, subtract 7.5 from both sides:

Step 2, divide both sides by 8.5:

Correct answer choice is B

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
