Answer:
x=71
Step-by-step explanation:
All exterior angles add up to 360
x+x-6+x+4+x+2+x+5=360
combine all the x's
5x-6+4+2+5=360
add all the numbers
5x+5=360
isolate 5x by cancelling out 5
5x+5-5=360-5
simplify
5x=355
isolate the variable
5x/5=355/5
simplify
x=71
z is inversely proportion to x
⇒ z = k/x where k is a constant.
<u>Find k:</u>
Whe x = 16, z = 0.875
16 = k/0.875
k = 16 x 0.875
k = 14
Therefore z = 14/x
<u>When x = 21, find z:</u>
z = 14/21
z = 2/3
Answer: z = 2/3 or 0.67 (nearest hundredth)
Answer:
c=37
Step-by-step explanation:
Answer: 20.57142857
Step-by-step explanation:
148 = 3x + 3 + 4x + 1
Step one: combine like terms
148 = 7x + 4
Step 2: Subtract the 4 over to 148
144 = 7x
Step 3: Divide 7 on both sides
20.57142857 = x
