Answer:
.62
Step-by-step explanation:
first move the decimal 3 places to make it a whole number and now we have 4960, now we divide 4960 by 8 giving us 620, now we move the decimal 3 places back and it gives us the decimal .62.
x=3, y= -2
Multiplying :
(4x+3y =6)*-3
(3x+5y =-1)*4
-12x -9y= -18
12x+20y= -4
Add the equations
20y-9y = -4-18
11y = -22
y= -22/11 = -2
3x +5* -2= -1
3x -10 = -1
3x = 10-1
x= 9/3 =3
15+7+(-2)=22-2=20 hunx
Answer:1
Step-by-step explanation: solving for d
16.4
Step-by-step
BCD= 15
3x-15+?=180
3x=180
x=60
3(60)-15=180
180-15=165
