156. you basically just need to multiply 78 by 2
Answer:
73.07%
Step-by-step explanation:
Given that,
Actual value of sold cookies = 26
Assumed value of sold cookies = 45
We need to find Gabby's percent error. The percentage error in a value is given by :
Error = ](Assumed value - Actual value)/Actual value]× 100
So,

So, Gabby's percent error is equal to 73.07%.
An equation represents a line that passes through (-2, 4) and has a slope of 2/5 is y-4 = 2/5(x+2)
<h3>Equation of a line</h3>
The equation of a line in point-slope form is expressed as;
y-y1 = m(x - x1)
where
m is the slope
(x1, y1) is any pint on the line
Substitute the given parameter
y - 4 = 2/5(x-(-2))
y-4 = 2/5(x+2)
Hence an equation represents a line that passes through (-2, 4) and has a slope of 2/5 is y-4 = 2/5(x+2)
