Final answer: x=-11
1. distribute 4(x+9)
5+4x+36=-3
2. combine like terms
4x + 41 = -3
3. subtract 41 from each side
4x = -44
4. divide 4 from each side
x=-11
Answer:
S=194, L=75 L+S=269, 4L+1S=$494
Step-by-step explanation:
112
160 divided by 10 equals 16
16 x 3 =48
160- 48= 112
That should be right.
-3x - 4y - 2z = 0
x + 3y + 2z = 1
-2x - y = 1
-4x - 4y - 2z = 10
3x + 4y +2z= 0
-x = 10. x = -10
-2(-10) - y = 1
20 - y = 1
-y = -19
y = 19
-10 + 3(19) + 2z = 1
-10 + 57 + 2z = 1
47 + 2z = 1
2z = -46
z= -23
check: 2(-10)+2(19)-23=-5
-20+38-23=-5
-43+38=-5
-5=-5
We know that 1 yard equals 3 feet, therefore, we have:
65(3) + 2
= 195 + 2
= 197
therefore, 65 yards and 2 feet equals 197 feet
