(180-30)/2 would be the equation and the answer is 150/2
Answer:
2950
Step-by-step explanation:
i just subtracted 3,000 with 50
The angles of a quadrilateral add to 360, so we can solve for x by adding the 4 angle measures together and setting it equal to 360:
90 + 140 + (x - 10) + (x - 20) = 360
Combine like terms:
230 + 2x - 30 = 360
200 + 2x = 360
200 - (200) + 2x = 360 - (200)
2x = 160
Divide both sides by 2:
2x/(2) = 160/(2)
x = 80
Answer: 0.28
Step-by-step explanation:
Let´s name the proportion of orders
- with no optional features: "N"
- with one optional feature: "O"
- and the proportion of orders with more than one optional feature: "M"
<em>The sum of all of these proportions is equal to the total quantity of orders.</em>
Therefore,
N + O + M = 1
Then, substracting N and O on each side of that equation,
the proportion of orders with more than one optional feature (M) is:
M = 1 - N - O
M = 1 - 0.38 - 0,34
M = 0.28
