Answer:
Step-by-step explanation:
3*(4x - 3) = 63 Divide both sides by 3
4x - 3 = 63/3
4x - 3 = 21 Add 3 to both sides
4x = 21 + 3
4x = 24 Divide by 4 on both sides
4x/4 = 24/4
x = 6
Note: The perimeter is the sum of all three sides. One side is 4x - 3 All 3 sides must be 3*(4x - 3)
The
correct answer is:
TrueExplanation:
1.
(Straightforward)
2.
(log to base of itself is always 1)
3.
(Using log power property)
Hence the correct option is True.
x+y=3
+ x-y=1
2x=4
x=2
x+y=3
2+y=3
-2. -2
y=1
(2,1)
Y=250+2x is the amount she spends
y=12x is the amount she makes
If the amount she spent = the amount she makes then she break even
250+2x=12x
250=12x-2x
250=10x
So x = 250/10=25 necklaces she needs to sell to break even
Answer is 25 necklaces
