48$ sense 12+12+12+12= 48 if added right or you can do 12*4= 48
BD=90 DF=110 meaning BF=200
200/5x
X=40
What subject is this? ill comment the answer when i know
Answer:
52
Step-by-step explanation:
This can be
solved by solving the slope of the line. First let y be the rating of the test
and x be the number of incorrect answers. Slope can be solved using the formula:
M = ( y2 –
y1 ) / ( x2 – x1)
M = ( 90 –
98) / ( 5 -1 )
M = -2
<span>So the model
has a negative slope</span>
