Answer:
$512
Step-by-step explanation:
If each crown is 2 dollars, then 256 x 2 would be the answer. The answer would be 512.
Answer:
g = 
Step-by-step explanation:
Given
2(g - h) = b + 4 ← distribute parenthesis on left side
2g - 2h = b + 4 ( add 2h to both sides )
2g = b + 4 + 2h ( divide both sides by 2 )
g = 
Let x= months
So 50x is the total amount he pays after x months. You went to add 100 to this because there's a fixed cost of 100 for the phone
So you have the expression 100+50x which is the amount he pays after x months
Since he has a limit of 300,
100+50x < 300
Answer:
x = -1
Step-by-step explanation:
When an exponent is negative, you have to move it to the denominator (or to the numerator if it's already on the denominator). Since the answer is
, you know that the 2 has been raised to the power of 1 (any number to the power of 1 is the same number), so you just make it negative. Hope that helps!
