Answer:
1:12−3z
2:6n
3:11c
4: 12-3z
Step-by-step explanation:
1:
9 - z +3 - 2z
(9+3)+(−z−2z)
<u>12−3z
</u>
2:
n +5n
<u>6n</u>
3:
12c - c
<u>11c</u>
4:
9 - z + 3 - 2z
(9+3)+(−z−2z)
<u>12-3z</u>

Answer:
b= 10 miles/hr and c= 5 miles/hr
Step-by-step explanation:
Let it's downstream and upstream speed be d and u respectively
also speed of the boat be b and speed of stream be c.
as per question d = 150/10= 15 miles/hr
and, u= 150/30= 5 miles/hr
also we know d= b+c = 15.....i and u = b-c= 5....ii
solving i and ii we get b= 10 miles/hr and c= 5 miles/hr
The value of x from the diagram is 18degrees
An angle is a line where two or more lines meet.
The magnitude of two lines is known to be parallel if they have the same magnitude.
From the diagram shown, we can see that line BC is parallel to line ED
This shows that the following are true:
- <C = <D
- 8x and 2x are supplementary
If the two angles are supplementary, then:
8x + 2x = 180
10x = 180
x = 180/10
x = 18 degrees
Hence the value of x is 18degrees
