Answer:
the solution is (-8, 4)
Step-by-step explanation:
Let's use the addition/subtraction method here to eliminate one variable:
-x+y=4
x+3y=4
Combining these two equations results in
4y = 8, so that y = 2. Substituting y = 2 into the second equation, we get:
x + 3(2) = 4, or x = -2.
Then the solution is (-8, 4)
Answer:
32 minutes.
Step-by-step explanation:
Hello there!
Add the time of the movie to the time they arrived:
10:15+48=11:03
Then subtract this number from 11:35
11:35-11:03=32 minutes
:)
Rewrite 15 1/4% as 15.25%. To obtain the desired fraction, divide this 15.25% by 100%:
0.1525
This could be reduced to 61/400, which was obtained by first writing 0.1525 as 1525/10000.
Answer:
7z + 5 + 6z - 9 (Add 7z and 6z, subtract 9 from 5)
<em>13z - 4 </em>(Can't be simplified further)
