Answer:
$3.24
Step-by-step explanation:
2.16 / 12 = 0.18
0.18 per egg
0.18 x 18 =3.24
18 eggs = $3.24
For this case we have the following system of equations:
We multiply the first equation by -1:
We have the following equivalent system:
We add the equations:
Equality is not fulfilled, so the system of equations has no solution.
Answer:
Option C
<span>323° in radians
= 323 x pi / 180
= 5.6
answer is
</span><span>B. 5.6</span>
(-3,7)
5(-3)+2(7)=-1
-15+14=-1
Step-by-step explanation:
Equations:
Quantity:: d = n + 3
Value::: 10n + 5d = 615 cents
-------------------------------------------
Modify::
d - n = 3
d + 2n = 123
--------------------------------------------
Subtract and solve for "n"::
3n = 120
n = 40 (# of nickels)
d = n+3 = 43 (# of dimes)
