Answer:

a = \frac{67}{110}

Step-by-step explanation:

Given

44a - 0.5 = 33 - 11a ( add 11a to both sides )

55a - 0.5 = 33 ( add 0.5 to both sides )

55a = 33.5 ( divide both sides by 55 )

a = \frac{33.5}{55} ← multiply numerator/ denominator by 2

a = \frac{67}{110} ← exact solution

Barbara, Mark, and Carlos participated in the third heat of “The Big Race”. Barbara thought she could win with a 3 meter head st
steposvetlana [31]
Distance to travel = 20 m.
Let us determine the time, t, that each participant took to complete 20 m.

Barbara:
Average speed = (3 m)/(2 s) = 1.5 m/s
t = 20/1.5 = 13.3 s

Mark:
t =  5 s

Carlos:
y = x + 1
where
y = 20 m
x = time, t
Therefore
t =x = y - 1 = 20 - 1 = 19 s

Summary:
Barbara:  13.3 s
Mark:       5 s
Carlos:     19 s

Answer:
The winner is Mark

What is the y-intercept for the graph of 7x – 3y = –5?
AysviL [449]
2 ways to find the y int.

(1) put the equation in y = mx + b form and the y int will be in the b position
7x - 3y = -5
-3y = -7x - 5
y = 7/3x + 5/3....so 5/3 is ur y int

(2) another way is to sub in 0 for x and solve for y
7(0) - 3y = -5
-3y = -5
y = -5/-3
y = 5/3...ur y int
