Equation 1. N+D=500
equation 2 5N+10D=3000
This is for equation 1
N=500-d
Substitute into equations 2 and solve for D
5N+10D=3000
5(500-D)+10D=3000
2500-5D+10D=3000
5D=500
D=100
Lets go back the equation 1
N=500-D
N=500-100
N=400
there are 400 Nickles and 100 Dimes
The correct answer for this question is this one:
<span>- A adjacent angles
-D supplementary angles
The relationship that describes angle 1 and angle 2 is that they are adjacent angles -- at the same time they are also supplementary angles.</span>
Hope this helps answer your question and have a nice day ahead.
Answer:
1/400
Step-by-step explanation:
3/1200 = 1/400
1) Sample space would consist of the 1200 names of the students
2) out of those 1200 outcomes, this event composes of three outcomes which are:
1) Sophie
2) Hannah
3) Ethan
1. a. 0=0, 4x=4x, -18=-18
b. 3
2.a. 0=-2, 2= 0
b. 2
