The number is x
x of 55% = 94
x * (55/100) = 94
x = 9400 / 55
x = 170.91
I think it’s 32
Step-by-step explanation:
The answer is 10-2i. Solve whats it the second parenthesis, remove the first parenthesis, and then add the 2 (from -3+1)
Answer:
y = 0.47x + 25
y1 = 41.45 and not 55.55
Step-by-step explanation:
Given that:
x = number of brochures
y = total. Cost
Total cost of 35 brochures = $41.45
Total cost of 65 brochures = $55.55
The ordered pairs :
(x1, y1) ; (x2, y2)
x1 = 35 ; y1 = 41.45 ; x2 = 65 ; y2 = 55.55
(35, 41.45), (65, 55.55)
The slope :
Slope (m) = change in y / change in x
m = (y2 - y1) / (x2 - x1)
m = (55.55 - 41.45) / (65 - 35)
m = 14.1 / 30
m = 0.47
The y intercept :
y - y1 = m(x - x1)
y - 41.45 = 0.47(x - 35)
y - 41.45 = 0.47x - 16.45
y = 0.47x - 16.45 + 41.45
y = 0.47x + 25
Lila incorrectly chose 41. 45 as y1
