Answer:
in the space of x we'll equate it to 5-y
2(5-y)+3y=12
10-2y+3y=12
-2y+3y=12-10
y=2
subt y into first equation (x=5-y)
x=5-2
x=3
The correct answer is B
325-45=280
8x35=280
6 roses + 4 carnations + 8 tulips = $14
that would be 12 flowers, so each flower would be less than $1, which seems feasible.
Almons:walnuts:rasins=1:2:3
x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y
3x=z
subsitute
12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts
2x=y
2(1/3)=y=2/3
2/3 pounds of almonds
3x=z
3(1/3)=z
1=z
1 pound of rasins
1/3 pound walnuts
2/3 pound almonds
1 pound rasins
Answer:
Prime
Step-by-step explanation:
- As there is no common between 5y and 7 except 1 as factor.
- Hence its not factorable
