T = 2D + 5
5 + 2x should be your answer
hope this helps
Answer:
a) x=-15
b) x= 27
c) x=14
Step-by-step explanation:
a) x/-3+1=6 x/-3=5 (-3)x/-3=5(-3) x=-15
-1 -1
b) 3-x/9=0 -x/9=-3 (-9) -x/9=-3(-9) x=27
-3 -3
c) x/-2+4=-3 x/-2= -7 (-2)x/-2= -7(-2) x=14

Step-by-step explanation:
LM = MN
11x - 21 = 8x + 15
x = 12
LM = 11(12) - 21 = 132 - 21 = 111
MN = 8(12) + 15 = 96 + 15 = 111
LN = 111 + 111 = 222
Answer:
b = 33 miles
Step-by-step explanation:
The illustration forms a right angled triangle. The opposite side of the triangle is where we are looking for . The adjacent side is the radius 4000 miles.
5280 ft = 1 mile
735 ft = ? miles
cross multiply
735/5280
miles = 0.13920454545 miles
The hypotenuse side is the height of the building + 4000 miles = 0.140 + 4000 = 4000.14 miles
using Pythagoras theorem
c² = a² + b²
c = 4000.14
a = 4000
4000.14² = 4000² + b²
b² = 4000.14² - 4000²
b² = 16001120.0196 - 16000000
b² = 1120.0196
b = √1120.0196
b = 33.4666938911
b = 33 miles
