A student answers
Marina CMI [18]
So, we have the percentage she gets which is, 90% and the number of questions she answers correctly, which is 27

To find the number of questions in the exam, make an equation
(90% = \frac{90}{100} = 0.9)
\frac{90}{100} = \frac{27}{x}
cross multiply and equate them
90x = 27 x 100
90x = 2700
divide by 90 on either sides to isolate x in order to find the answer
\frac{90x}{90} =  \frac{2700}{90}
90 and 90 cancels out
x = 30
So your final answer will be, there were 30 questions in the exam paper.

Answer:

B. y + 7 = -6/5 (x+3)

Step-by-step explanation:

Use the given slope and point to substitute into the point-slope formula  y − y 1 = m ( x − x 1 ) .

Slope-intercept form:  y = − 6 /5 x − 53 /5

Point-slope form:  y + 7 = − 6 /5 ⋅ ( x + 3 )
