26*5x = 849 * 57
130 x = 48393
x = 48393 / 130
x = 372.25</span>
3x+12=39
Minors 12 on both side
3x=27
Divide 3 on both side
X=9
Answer:
B
Step-by-step explanation:
Angles in a triangle add up to 180
Take 45 + 90 then subtract the answer from 180
The amount of money found under the couch cushion is $1.99
Simultaneous equations
Jamar=J
Josh=j
4J=j
20+J=2j
Then
4J=j
-4 (J)=-4(2j-20)
So
0=-7j+80
7j=80
j=80÷7
