Answer:
D. 6
Step-by-step explanation:
Suppose the triangles are similar:
The side lenghts would be proportional as follows
XZ/DF = XY/DE
12/8 = 9/x cross multiply expressions
12x = 72 divide both sides by 12
x = 6
Answer: 26/3 or 8 2/3
Step-by-step explanation:
In the addition or subtraction of fraction, first, you have to convert all of them into improper fraction if they are mixed; then, you need to find the LCD (Least Common Denominator).
<u>Converting fraction:</u>
5 3/4=23/4
2 11/12=35/12
<u>Finding LCD:</u>
4 and 12 is 12
<u>Converting fraction into common denominator:</u>
23/4=69/12
35/12=35/12
<u>Solve:</u>
5 3/4 + 2 11/12
=69/12 + 35/12
=104/12
<h2>=26/3</h2>
Answer:
y = -2/3 + 18
Step-by-step explanation:
2x + 3y = 18 ----- here is the equation...
-2x - 2x ----- bring the 2x to the other side
3y = -2x + 18 ----- now you have to divide everything by 3 to get y by itself
y = -2/3 + 18 ----- Done!
Answer:
6y+4
Step-by-step explanation:
-(2x-3y) +5x +2 -3x +3y +2
(-2x -3x +5x) (3y +3y) (2 +2)
0 +6y +4
6y +4
