Answer:
5,-1
Step-by-step explanation:
edited.... I gave 1/3 AC earlier (misread the Q)
This means AC is divided into fourths
x from 6 to 2 is -4 1/4th of this added to 6 is
6 - 1/4 * 4 = 5
y from 1 to -7 is -8 1/4th of this added to 1 is
1 - 1/4 * 8 = -1
Answer:
cos B = a/c
tan A = a/b
sin B = b/c.
Step-by-step explanation:
Sin = opposite / hypotenuse
cos = adjacent/ hypotenuse
tan = opposite/adjacent.
We want to subtract 8x + 3 from -2x+5. We can create an expression to represent this.
-2x + 5 - (8x + 3).
After this, lets distribute the - sign (think of this like expanding something with -1).
-2x + 5 - 8x - 3
Lastly, we just need to combine like terms.
-2x + 5 - 8x - 3
Combine the 5 and -3 to get 2.
-2x + 2 - 8x
Combine the -2x and -8x to get -10x.
-10x + 2
The final answer to the question is therefore A.
Answer:
120 bricks = 10 kg
120 bricks × 10 kg = 1200 kg
1200 kg + 9000 kg = 10200 kg
