Answer:
x= 1
y= -2
Step-by-step explanation:
1. y+3x=1 subtract 3x from both side to get y= 1-3x
2. Put the new found y value in the equation
3x-4(1-3x)=11
3. Distribute the 4
3x-4+12x=11
4. Add 4 to both sides
3x+12x=15
5. Add the x's
15x=15
6. Solve for x
x=1
7. Plug in the x in the y equation y= 1-3x
y=1-3(1)
8. Solve for y
y= -2

Answer:the answer is c
Step-by-step explanation:
C is your hypotenuse and a/b are the legs A = 5 B = 12 OR A = 12 B = 5 Either work. I'll stick with the first one. c^2 = 12^2 + 5^2 c^2 = 144 + 25 c^2 = 169 c = sqrt 169 c = 13 Ans: 13 inches (dont forget your units!)
Answer:
D. divide 12 from both sides
Step-by-step explanation:
12x = 60,
Divide each side by 12
12x/12 = 60/12
x = 5
