Answer:
2 students.
Step-by-step explanation:
add together all of the students and then subtract that from 40.
20+15+3 = 38
40-38 = 2
Answer:
28 inches
Step-by-step explanation:
To find the value of x you put them into an equation of: (x+6) = (3x+2), this would let you find that x=2, since 2+6 = 6+2. Once you've plugged that in all you need to do is add together all the sides, and since side A and side B are both 8 you do 12+16 to get the perimeter of 28 inches.
Answer:
x = 17
Step-by-step explanation:
A triangle's sum is 180 degrees, hence
6x + 10 + x + 17 + 4x - 34 = 180.
11x + 10 + 17 - 34 = 180
11x - 7 = 180
11x = 187
x = 17
hope this helps and is right!! p.s. i really need brainliest :)
Answer:
y= -9x+14
Step-by-step explanation:
the equation of a straight line is y=mx+c
m is the slope
And we are given a y and x term
So we substitute these into the equation:
5= -9(1) + c
rearragne to find c
14= c
so the full equation is:
y= -9x+14
