Answer:
28°F
Step-by-step explanation:
We can find the change in temperature by subtracting 44 from 72:
72 - 44 = 28
So, the change in temperature was 28°F
The system of equations x+y=46 and 15x+9y=396 could be used to find the number of boxes of each item sold.
Step-by-step explanation:
Given,
Cost of one box of raspberry scones = $15.00
Cost of one box of lemon poppy seed muffins = $9.00
Total boxes sold = 46
Total revenue earned = $396
Let,
x be the number of raspberry scones sold.
y be the number of lemon poppy seed muffins sold.
According to given statement;
x+y=46 Eqn 1
15x+9y=396 Eqn 2
The system of equations x+y=46 and 15x+9y=396 could be used to find the number of boxes of each item sold.
It’s B bc $2.50 divides by 10 is $0.25 and that means you take $0.25 and times it by 18 and get the price
Let us write the inverse variation in the given in an equation form,
a = k / b
where k is the constant of proportion.
If the value of b is double, there should be a corresponding change in a.
(x)(a) = k / 2b
(x)(a) = (1/2)(k/b)
The value of x is 1/2. Therefore, the value of a is halved.
