Answer:
x+18
Step-by-step explanation:
Combine Like Terms:
=4x+3+−3x+15
=(4x+−3x)+(3+15)
=x+18
16. The open circle is excluded and closed is included.
x≤-6
x>2
17. The open circle is excluded so the inequality would be: -3<x<2
Answer:
First equation : 3, 0, -3, -6
Second equation : 2, 2.5, 3, 3.5
Step-by-step explanation:
What the first equation is basically saying is subtract 3 each time.
What the second equation is basically saying is add 0.5 each time.
Then we just add/subtract to find the first four terms.
Jill = x
Jack = x + 1 1/3
X = 5 1/2
Solving Equations
5 1/2 +1 1/3
=6 5/6
Answer = 6 5/6 hours
Answer:
Widyh = 8 units
Step-by-step explanation:
Perimeter = 2/width+length)
then:
48 = 2(W+L)
W = L-8
W = Width
L = Length
then:
48 = 2((L-8)+L)
48 = 2(2L88)
48 = 2*2L - 2*8
48 = 4L - 16
48 + 16 = 4L
64 = 4L
L = 64/4
L = 16
W = L-8
W = 16-8
W = 8
Check:
48 = 2(16+8)
48 = 2*24
