16y=6x+42
16/16y=6x/16+42/16
y= 3x/8 + 21/8
I think the answer would be 25.11 , hope this helps .
The answer is 5/4 because that’s what you multiply the left triangle dimensions by to get the right triangle dimensions
Answer:
B.11.4
Step-by-step explanation:
The sum the 3 angles of a triangle add to 180 degrees
5x+8x+2x+9 = 180
15x+9 =180
Subtract 9 from each side
15x+9-9 =180-9
15x = 171
Divide by 15
15x/15 =171/15
x =11.4
Answer: 3.5 in
Step-by-step explanation
∡DOC=90°
DC=7
OC=5
Using Pytagora equation:
DO=√DC²-OC²
DO=√49-25
DO=2√6
Use Equation for area of triangle:
area of ΔDOC=a*Ha/2
DC=a=7
Ha=x---hight of ΔDOC
Area of ΔDOC=DO*OC/2
2√6*5/2=5√6
5√6=7*x/2
10√6=7*x
x=10/7√6
x=24.5/7
X=3.5 in
