Answer:
1/6, 1/6, 630
Step-by-step explanation:
1/6*n-7≤98
1/6*n≤98+7
1/6*n≤105
n≤105*6
n≤630
Answer:
Step-by-step explanation:
t = 158 Corresponding angles
t + s = 180 They are supplementary angles
158 + s = 180 Subtract 158 from both sides
s = 180 - 158
s = 22
As a note, all angles in this situation are either 158 or 22.

Step-by-step explanation:
you had putten 5 cities not 3
Answer:
1. 8/24
2. 9/27
3. 5/15
4. 10/30
5. 2/6
6.1/3
Step-by-step explanation:
Start with 1/3 then multiply that by the number that is given.
#1)
Answer:
x=1 and y=12
Explanation:
y=5x+7
y=2x+10
This system should use substitution because the value of y is given in terms if x.
Substitution:
5x+7=2x+10
Solve:
3x=3
x=1
Substitute x to solve for y by plugging x into one if the original equations(doesn’t matter which one is used).
y=5x+7
y=5(1)+7
y=5+7
y=12
#2)
Answer:
x=-8 and y=2
Explanation:
y=2x+18
9y=-2x+2
This system also uses substitution. The value of y us already given in terms if c in the first equations, so we will substitute in the second equation.
Substitute:
9(2x+18)=-2x+2
Solve:
18x+162=-2x+2
20x=-160
x=-8
Now that we have the value if x, plug it into one of the original equations(doesn’t matter which equation) and substitute to find y.
y=2x+18
Substitute:
y=2(-8)+18
Solve:
y=-16+18
y=2
