Answer:
y = 14
Step-by-step explanation:
∠BCF and ∠EFH are same side interior angles and are supplementary, hence
5x - 66 +2x + 50 = 180
7x - 16 = 180 ( add 16 to both sides )
7x = 196 ( divide both sides by 7 )
x = 28
∠BCF = 5x - 66 = (5 × 28) - 66 = 140 - 66 = 74
∠ACD = ∠BCF ( vertical angles ), hence
9y - 52 = 74 ( add 52 to both sides )
9y = 126 ( divide both sides by 9 )
5+11i-16-4i+9i
5-16+11i-4i+9i
-11+7i+9i
-11+16i
First, get the like terms together. Then add or subtract until its simplified. Simplified is -11+16i.
D = 0 , Dx = 4 , Dy = -6 , Dz = 2
As per<u> cramer's rule</u>,
D = | 7 6 4 | = 0
| 3 3 3 |
| 4 4 4 |
Dx = | 10 6 4 | = 4
| 1 3 3 |
| 2 4 4 |
Dy = | 7 10 4 | = -6
| 3 1 3 |
| 4 2 4 |
Dz = | 7 6 10 | = 2
| 3 3 1 |
| 4 4 2 |
As Doris Day said: Good morning to you
Answer 27/2
Let s equal the cost per shirt.
First, we are going to multiply the cost of one shirt to the sale of 25%
0.25s
Second, we are going to multiply by 3 since you are buying 3 shirts.
* 3
Put together.
0.25s * 3
Best of Luck!
