Hannah spends $4.50 each day to buy lunch at her school. after school each day, she buys the same snack. hannah spends $28.75 for lunch and snacks each week. the equation and solution model the situation. 5(4.50 + x) = 28.75; x = 1.25 what does the solution, x = 1.25 represent?

It is given that she spend $4.50 on lunch each day and she buys same snack. Here x represents the amount spend on the snacks . So 5(4.50+x) represents total amount spend on both lunch and snack for the 5 days which is equal to 28.75 . And on solving for x, the solution is x=1.25 . So Hannah spend $1.25 on snack .

Variable A variable is a quantity that may change within the context of a mathematical problem or experiment. Typically, we use a single letter to represent a variable.

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%

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.
