Jack ate 3 chocolate squares after school. Each chocolate square had a mass of 8 grams.How many grams of chocolate did Jack eat in all?
Answers
Answer:
24 grams
Step-by-step explanation:
Since there are three of them, I multiply by the mass, which is 8, and get 24 grams. Hope this helps!
You can get this answer my multiplying 8x3 because he ate three pieces and each of the three had eight grams.

Jacob: 2x + 3y = 18.25
Zachary: 4x + 2y = 27.50
ok now you have to use these 2 equations to get the answer
4x + 2y = 27.50 ---> 2y = 27.50 - 4x ---> y = 13.75 - 2x
2x + 3y = 18.25
2x + 3(13.75-2x) = 18.25
2x + 41.25 - 6x = 18.25
-4x + 41.25 = 18.25
-4x = -23
x = 5.75 One bag of popcorn is $5.75
4x + 2y = 27.50
4(5.75) + 2y = 27.50
23 + 2y = 27.50
2y = 4.50
y = 2.25 One drink is $2.25
Answer:
Popcorn costs: $5.75, and drink costs: $2.25.

The given expression -8 ÷ 343 can situationaly be written in power notation as -8 ÷ 7^3. This transformation changes '343' to '7^3' since 343 is 7 cubed.
Explanation:
The expression -8 ÷ 343 cannot be directly written in 'power notation', as the concept of'power notation' commonly refers to writing an expression in the form of a base value raised to an exponent.
Power notation is typically represented as a^n, where 'a' is the base and 'n' is the exponent. However, '343' can be written in power notation since it is 7 cubed (7^3).
So, while we should clarify the details, one way to write the expression could be -8 ÷ 7^3.

Okay, the price before was $256, then it goes down to below 20. I think the answer is $12.80, because I said 256 ÷ 20 = 12.8, which can be turned into $12.80
Brainliest if it is correct!
price drop is following this pattern
256, 128, 64, 32, 16 . . . .
so you can see 16 is the price which is less than 20 $. you can also solve it by using GP

Answer:

Step-by-step explanation:
To evaluate the expression 20 - {3 × 8 - 5 - (3 - 25 ÷ 5)}, follow the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders (i.e., powers and square roots, etc.), Multiplication and Division (left-to-right), and Addition and Subtraction (left-to-right):
Inside the innermost parentheses, we have:
3 - 25 ÷ 5
= 3 - 5
= -2
Now, the expression becomes:
20 - {3 × 8 - 5 - (-2)}
Next, perform the multiplication and subtraction inside the innermost braces:
3 × 8 = 24
5 - (-2) = 5 + 2 = 7
The expression becomes:
20 - {24 - 7}
Continue inside the braces:
24 - 7 = 17
Now, the expression becomes:
20 - 17
Finally, subtract:
20 - 17 = 3
So, the value of the expression is 3.
Following the steps of the BODMAS rule, the expression simplifies to -1.
The question involves arithmetic operations such as subtraction, multiplication, and division. The correct order of these operations is dictated by the BODMAS rule, which stands for Brackets, Orders (powers and square roots, etc.), Division and Multiplication (left-to-right), Addition and Subtraction (left-to-right).
According to this rule, begin by calculating within the deepest set of brackets: 25 ÷ 5 = 5. Your expression now becomes: 20 - {3 × 8 - 5 - (3 - 5)}, which simplifies to 20 - {3 × 8 - 5 - -2}. The next step is to calculate the multiplication: 24 - 5 - -2, which further simplifies to 20 - {24 - 5 + 2}, which becomes 20 - {21}, leading to a final result of -1.
