Answer: First degree equation
Step-by-step explanation:
For each hour from 5pm , the temperature decreases 5F. So, let the variation of time t , the constant -5, and the final temperature, T:
T=5t-5 .: for 5pm , variation is 0,so T in F is -5.
Answer:
A
Step-by-step explanation:
<u>Two variables would be proportional to each other if their ratios are equal. </u>
Here we are going to check BAGS and PRICE.
If the ratio for all 3 columns are same, then they are PROPORTIONAL.
All are and same. Thus, they are proportional. Answer choice A.
** We could have also divided price by bags, all would have still be the same [5] **
Let's assume x= greater number and y= smallest number.
Given, a greater number is seven less than five times a smaller number. Which can be transformed into an algebraic equation as follows:
x= 5y-7 ..... (1)
Now the sum of two numbers is 41. So,
x+y= 41 ...(2)
Now we can plug in x=5y-7 in equation (2). So,
5y-7+y=41
6y-7=41
6y-7+7=41+7 Add 7 to each sides of the equation.
6y= 48
Divide 6 to each sides.
So, y=8
Next step is to plug in y=8 in equation (1). So,
x=5(8)-7
=40-7
=33.
So, the numbers are 8 and 33.
