Step-by-step explanation:
Answer:
Step-by-step explanation:
To find:
Given:
Isolate the term of p, from one side of the equation.
Combine like terms.
Add the numbers from left to right.
-p+2p+3p=4p
7p+4=4p+9
Then, you subtract by 4 from both sides.
Solve.
7p=4p+5
Subtract by 4p from both sides.
7p-4p=4p+5-4p
Solve.
Divide by 3 from both sides.
3p/3=5/3
Solve.
p=5/3
Divide is another option.
5/3=1.6666
So, the final answer is 3p=5.
I hope this helps, let me know if you have any questions.
Answer:
49
Step-by-step explanation:
10 more than means 10 greater than = + 10
So you simply add 10 to 39
39 + 10 = 49
integer to represent the total temperature change.
Answer:
I think the integer that represents the change in temperature is -15.
The expression representing the temperature change is 3 * -3, and the total temperature change, calculated from this, is -9 degrees.
In this problem, we are given that the temperature dropped 3 degrees every hour for a total of 3 hours. To find the total temperature change, we must multiply the number of hours by the change in temperature every hour. So, the expression to represent this situation is 3 * -3.
To find the total temperature change, we plug in the given numbers into the expression. This results in -9. The negative sign indicates a drop in temperature. So, the integer representing the total temperature change is -9 degrees.

To solve for 'b' when 'a' = 21 in a direct variation relationship where 'a' = 7 when 'b' = 2, first determine the constant of proportionality. Then, insert 'a' into the formula and solve for 'b'. The solution of 'b' would be 6.
In this scenario, we are given that a varies directly as b, which means we can state this relationship as a = kb, where k is a constant of proportionality. Initially, we're given that a = 7 when b = 2. From this, we can find that k = a / b, so k = 7 / 2 = 3.5. Therefore, our direct variation equation is a = 3.5b.
When a = 21, we can substitute this into the direct variation equation and solve for b. Thus, 21 = 3.5b, and by dividing both sides by 3.5, we can find that b = 6.
