Answer:
Each daylilies cost $7
Step-by-step explanation:
Step one:
let roses be x
and daylilies be y
so
8x+15y=193--------------1
also
3x+12y=117--------------2
we can solve equations 1 and 2 by substitution
8x=193-15y
x=(193-15y)/8
put x= (193-15y)/8 in 3x+12y=117
3((193-15y)/8)+12y=117
(579-45y)/8+12y=117
579-45y=8(117-12y)
579-45y=936-96y
collect like terms
579-936=-96y+45y
-357=-51y
divide both sides by -51
y=-357/-51
y=7
Hence each daylilies cost $7
put y=7 in eqn 1
8x+15(7)=193
8x+105=193
8x=193-105
8x=88
x=88/8
x=11
rose cost $8
The value of x
3x°+46°+(2x-1°)=180°(angle sum of △)
5x+45=180°
5x=180°-45
x=135÷5
x=27
x is 27
put x into angle B,we have
2(27)-1
=53
thus angleB is 53°

Answer:
240
Step-by-step explanation:
ok, so first you look closely at the problem. convert pounds to ounces, since you dont have enough to do it the other way. so if 1 pound is 16 ounces, 3 pounds is 48. he has 48 ounces. if 10 ounces makes 60, 40 ounces makes 240. now you have 8 left. now im not sure about this part, but if you took the 8 left over, and if 10 ounces makes 60, 8 ounces makes 48 more.
