2. Write an integer to represent owing your friend $10.
–10 ***
–2
2
10
3. Write the sum as a product, then simplify the product.
(–8) + (–8) + (–8) + (–8) (
2(–8) + 2(–8) = –30
4(–8) = –32 ****
4(–8) = 32
5(–8) = –40
4. What is the value of the expression below?
|-4 -3| - |6 -2|
-11 ***
-3
3
5. Which word phrase could represent the variable expression 3d + 5? Let d = Beth's age.
five more than Beth’s age times three ***
three times Beth’s age minus five
five times Beth’s age plus three
three minus Beth’s age times five
4 is wrong
5 is wrong.
Sorry. I left out an ption D on #4.
Would the answer be 11? on four?
5. C or B?
For number four think about it, all you have to do is (4 - 3) - (6 - 2) so that =
1 - 4 which equals -3 so for number four the answer is -3
I don't agree that the answer to #4 is -3.
To answer these questions, follow these steps:
2. To represent owing your friend $10, you would use the integer -10.
3. To write the sum as a product, you would multiply the number by the number of times it appears. In this case, you have (-8) four times. So, (-8) + (-8) + (-8) + (-8) can be written as 4(-8). Simplifying the product gives you -32.
4. To calculate the value of |-4 -3| - |6 - 2|, you need to perform each subtraction separately, then find the absolute value of each difference, and finally subtract the two results. |-4 - 3| is equal to |-7|, which is 7. Similarly, |6 - 2| is equal to |4|, which is also 4. Subtracting 4 from 7 gives you the result of -3.
5. The variable expression 3d + 5 represents a quantity involving Beth's age, where d is Beth's age. Among the given options, "five more than Beth’s age times three" best represents 3d + 5.
