Answer:
97
Step-by-step explanation: 65+43=108
108-11=97
Answer:
y = 7/6x + 4/3
Step-by-step explanation:
find slope first
change in y over the change in x
-1-6/-2-4 = -7/-6 = 7/6
to be extra sure use this formula to find the y-intercept or b
y - 6 = 7/6 (x -4)
you can plug in either point
solve for y and you have the equation in slope intercept form or y=mx+b
Answer:
9+11i
Step-by-step explanation:
The numbers are 3 and 18
Step-by-step explanation:
Step 1: Given details are sum of numbers = 21, let the numbers be x and y. Form equations out of the given details.
⇒ x + y = 21 ---- (1)
⇒ y = 6x --------- (2)
Step 2: Substitute (2) in (1)
⇒ x + 6x = 21
⇒7x = 21
⇒x = 3
- Step 3: Find the value of y using x
⇒ y = 6 × 3
⇒ y = 18
Answer:
18 sides.
Step-by-step explanation:
The interior and exterior angles sum to 180 so:
I + E = 180
also I - E = 140 (given)
So, adding to eliminate E:
2I = 320
I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.
Since the sum of all exterior angles in a polygon = 360 degrees
- the number of sides = 360 / 20 = 18.
