Let the first page = x
The second page would be x + 1
Add them together to equal 347
X + x + 1 = 347
Combine like terms:
2x + 1 = 347
Subtract 1 from both sides
2x = 346
Divide both sides by 2:
X = 173
The smaller page number is 173
The larger page number is 174
Answer:
48
Step-by-step explanation:
(204-x)/2=78
or, 204-x=156
or, x=204-156
or, x=48
Remember that straight lines are 180°. For #1 angle 1 would be 40°, since 140°+40°=180°
Answer:
Step-by-step explanation:
100-15=85
85 % of x=19,320
x=19,320 ×100/85≈22729.41
X - 3y = -1
-x - 3y = 1
---------------add
6y = 0
y = 0
x - 3y = -1
x - 3(0) = -1
x = -1
one solution...and that is (-1,0)
