Answer:
5,000
Step-by-step explanation:
1,267 + 3,894 = 5161
X+3x-11=4
4x=4+11
x=15/4
x=3.75
Answer:
15 49-cent stamps
Step-by-step explanation:
We can solve this problem with the equations <em>0.49(x) + 0.21(y) = 9.45 </em>and <em>x - 5 = y</em>. Well, 0.49(15) + 0.21(10) = 9.45, so we know that there are 15 49-cent stamps and 10 21-cent stamps. The question is asking for the number of 49-cent stamps, so we can tell Travis bought 15 49-cent stamps.
Hope this helps! Plz give me brainliest, it will help me achieve my next rank.
Cancel by elimination
4x+y=2
x-y=3
5x=5 because the Ys cancel out because it is positive and negative
x=1 when you divide by 5 on both sides to find x
then plug 1 in for x in a equation then solve
4(1)+y=2
4+y=2
y=-2 when you subtract 4 on both sides
(1,-2)
