Answer:
215 mm
Step-by-step explanation:
1 cm = 10 mm
21.5 cm * (10 mm)/(1 cm) = 215 mm
Answer: 215 mm
Since we have that the slope is m = 7/9 and the y-intercept is b = 12, we can write the equation of the line in slope-intercept form:

to find three coordinate points, we can use arbitrary values on x to get the y-coordinate. To make things easier, let's use x = 9, 18 and 27:

therefore, the line with slope m = 7/9 and y-intercept 12 passes through the three points (9,19), (18,26) and (27,33)
Answer:
The possible number of hours the chemistry club can rent the meeting room is 7 hours.
Step-by-step explanation:
h=hours
19+4h=47
Subtract 19 from both sides of the equation.
4h=28
Divide 4 from both sides of the equation.
h=7
The possible number of hours the chemistry club can rent the meeting room is 7 hours.
Hope this helps :)
Answer:
=−2x^2−9x−10
Step-by-step explanation:
would you like an explantion or are you good
The answer is 280 because if you multiply 400 by .3 you get 120 and if you subtract 120 from 400 you get 280
