Answer:
x = (c-2)/b
Step-by-step explanation:
5(c - bx) = 10
c - bx = 2
c - 2 = bx
(c - 2)/b = x
Question:
Lisa walks at an average speed of 6 km/h for 15 hours.
Dan completes the same distance in an hour. Calculate Dan's average speed.
Answer:
Step-by-step explanation:
Given
Lisa:
First, we calculate the distance covered by Lisa:
So, Dan distance can be represented as:
--- Dan completes the same distance as Lisa
-- Time to complete the distance
Dan's average speed is:
<em>Hence, Dan's average speed is 90km/hr</em>
Answer:
y = 4x + 2
Step-by-step explanation:
You would use point slope to solve this. y-y = m(x-x) m represents the slope. With your numbers it would look like this ------> y-6 = 4(x-1)-----> distribute the 4 -----> y-6 = 4x - 4 ------> add six on both sides ------> they cancel out on the left ------> y = 4x + 2. Hope this helped!!!!
the sum of the interior angles of a quadrilateral is 360°
[360 - (40 * 2)] : 2 =
280 : 2 =
140°
-------------------------------
140 + 140 + 40 +40 = 360°
