Answer:
m = 8
Step-by-step explanation:
5(m+5)=7m+9 (distribute & evaluate parenthesis)
5(m)+5(5)=7m+9
5m + 25 = 7m + 9 (move all m-terms to one side and constants to the other)
5m - 7m = 9 - 25 (evaluate both sides)
-2m = -16 (divide both sides by -2)
m = (-16) / ( -2) = 8
Same height when both equations are equal
-16x^2 + 74x + 9 = -16x^2 + 82x
82x - 74x = 9
8x = 9
x = 9/8
x = 1.125
x = 1.13 ---->rounded to nearest hundredths of seconds
answer
1.13 seconds
Answer:
y=3/4x-4 and ignore this stuff ejdndjsienensmsk
The answer is 150 because
5*30
shortcut: 5*3=15
add the zero from the 50
150 is your answer..
Start with an equation summing all the angles in this triangle:
180 = <M + <N + <P
we are given <M and <N but not <P. But, since MN=NP, the angle <P is the same as the angle <M (isosceles, make a drawing to see). So
180 = 2<M + <N
180 = 2(3x+1) + x-11
180 = 7x - 9
x = 27
<P = 3*27+1 = 82 degrees
