Answer:
it is all of them because
Step-by-step explanation:
the first on is 8.94..
2,15.81
3,2.44
4,13
they all are rational number
When x = 3 z = 57 57/3 = 19
19*8 = 152
So when X is equal to 8, Z is equal to 152.
Answer:
(2, -2)
Step-by-step explanation:
First, you make 2 equations.
-6 + x = -4 (The -6 is from point A and the -4 is from point M)
3 + y = 1 (The 3 is from point A and the 1 is from point M)
Then you subtract -6 from each side of the first equation and subtract 3 from each side of the second equation.
You should get:
x = 2
y = -2
P is the cost of a pound of peanuts and F is the cost of a pound of dried fruit
0.5p+0.75f=6.5
0.75p+0.25f=4.5
Rearrange
0.5p=-0.75f+6.5
Simplify
P=-1.25f+13
Substitute
0.75(-1.25f+13)+0.25f=4.5
simplify
-0.9375f+9.75+0.25f=4.5
<span>-0.6875f+9.75=4.5
</span>-0.6875f=-5.25
f=7.636364
Round
F=$<span>7.64 per pound
</span>
Plug in
0.75p+0.25(7.64)=4.5
Simplify
0.75p+<span>1.91=4.5
0.75p=</span><span>2.59
</span>p=3.453333
Round
P=$3.45 per pound of peanuts
Final
P=$3.45 per pound of peanuts
F=$7.64 per pound of dried fruit
