Answer:d=0.8x+1
Step-by-step explanation:
To solve 0.5(2d-6)=0.2(4x-10)
Open the brackets
We get
d-3=0.8x-2
To make d the subject of formular
d=0.8x-2+3
d=0.8x+1
Mrs. Smith donated $20
The constant proportionality is $1 because no matter what, Mrs. smith will donate $1 for each mile. So if Sam were to only walk 1 mile, mrs. smith would donate $1. Or seen as a 1:1 proportion.
<u> P = 2(L +W)</u>
Divide each side of the equation by 2 : P/2 = L + W
Subtract W from each side : <em> P/2 - W = L</em>
Answer:
3.8888888888889
Step-by-step explanation:
Answer:
-17 degrees
Step-by-step explanation:
Given that:
Initial temperature = 2 degrees
Final temperature = -15 degrees
To Determine:
The change in temperature.
Solution:
First of all, let us have a look at the method for calculating the change in any quantity.
Let the initial quantity =
Let the final quantity =
Change in quantity = Final quantity - Initial quantity =
Here, we are given the quantity as temperature.
where degrees and
degrees
Therefore, the change in temperature = -15 - 2 = <em>degrees</em>
