If each journal weighs about 280 grams what will be the total weight of three journals is: 840 grams
Using this formula
Total weight=Number of journal × Weight of each journal
Where:
Number of journal=3
Weight of each journal=280 grams
Let plug in the formula
Total weight=3×280 grams
Total weight=840 grams
Inconclusion if each journal weighs about 280 grams what will be the total weight of three journals is: 840 grams

If we have the expression 2b = -3, then the value of the expression 1 - 4b is 4.
Step 1: Solving for 'b'
We are given the equation 2b = -3. To isolate 'b,' we need to get rid of the coefficient 2 attached to 'b'. To do that, we'll divide both sides of the equation by 2:
2b / 2 = -3 / 2
b = -3/2
Step 2: Substitute 'b' in the expression 1 - 4b
Now that we have the value of 'b' as -3/2, we can substitute it into the expression 1 - 4b:
1 - 4(-3/2)
Step 3: Simplify the expression
To simplify the expression, we'll perform the multiplication first:
1 + 6/2
Next, we add 1 and 6/2:
1 + 3 = 4

Answer:
Step-by-step explanation:
2b= -3, what is the value of 1 – 4b?
2b= -3
b = -3/2
Then 1 - 4b
= 1- 4(-3/2)
= 1+12/2
= 1+ 6
= 7
Scott had 150 cookies and sold 2/3 of them.
Dawn sold 46 cookies.
What percentage of the cookies sold were sold by Dawn?
Mike's score on the sixth test can be found by subtracting the total score after five tests from the total score after six tests (534 - 455), which yields a score of 79.
In order to solve this problem, we need to understand how averages work. The total score after five tests is 91*5, which amounts to 455. After the sixth test, the total average dropped to 89. To find the total score after six tests, you multiply 89*6, which gives us 534. The score for the sixth test can be found by subtracting the total score after five tests from the total score after six tests. So, 534 - 455 = 79. Therefore, Mike scored 79 on his sixth test.
