Answer:
pp
Step-by-step explanation:
X + y + z = 2
x - y + 5z = 6
cancelando +y com -y:
x + z = 2*(-5)
x + 5z = 6
-5x -5z = -10
...x +5z = 6
---------------------
-4x = -4 *(-1)
4x = 4
x = 4/4
x = 1
x + z = 2
1 + z = 2
z = 2 - 1
z = 1
x + y + z = 2
1 + y + 1 = 2
2 + y = 2
y = 2 - 2
y = 0
S: {x, y, z} = {1, 0, 1}
Answer: x= 2.5, y = 10
Step-by-step explanation:
<u><em>I'm going to assume that these photocopies are proportional in relations to each other.</em></u>
If they're proportional, you can set up two proportions:
And cross-multiply:
Then solved for x and y:
Answer:
Step-by-step explanation:
Smith=24
Munoz=32
Park=20
Total votes=24+32+20=76
Ratio of votes for Munoz to Smith
32:24
=4:3
Ratio of votes for Park to Munoz
20:32
=5:8
Ratio of votes for Smith to total votes
24:76
=6:19
Ratio of votes for Smith to Munoz to Park
24:32:20
=6:8:5
