Answer:
96
Step-by-step explanation:
The sum of the external angles of any convex polygon is 360°. Then the value of x° is ...
x° = 360° -130° -134°
x° = 96°
The value of x is 96.
Answer:
y = -3x + 4
Step-by-step explanation:
sorry im late
but all you have to do is isolate the y
so to do that we have to get rid of the 3x
3x + y = 4
in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y
3x + y = 4
-3x -3x
y = -3x + 4
and now y is isolated
Answer:
88.8%
Step-by-step explanation:
1.) 30-18= 12 which is the number of member that had an average of 84
2.)Then multiply 12 times 84 = 1008
3.) You multiply 18 by 92 which equals 1656
4.)Add 1008 and 1656 together and get 2664.
5.)Divide 2664 / 30 and you get the average of 88.8
Hope this helps :)

Answer:
9 labours
Step-by-step explanation:
In order to solve this, we must know which kind of proportionality is this. There are two types of proportions, direct and indirect/inverse proportions. In direct proportion, if one quantity increases, the other quantity also increases.
In indirect proportion, if one quantity increases, the other decreases and vice versa.
As per this question, we know if the number of labour increases, the number of days to complete a work decreases, thus proving that this is an indirect/inverse proportion.
6 labours => 12 days
x labours => 8 days
Since its an inverse proprotion, multiply 6 with 12, and x with 8.
8x = 6 × 12
x =
∴ x = <u>9 labours</u>
