Answer:
D
Step-by-step explanation:
To find a situation for 60−15x≥7, look for a story where 60 is a constant value that is decreasing by 15 for a number of times and where equal to or at least 7 is an option.
A. x would be weeks and it would decrease by 7x. This is not it.
B. 15 songs packages would have x be the number of packages not the price. This is not it.
C. This doesn't work either because if you want to owe them less than 7 it would have the sign < not >.
D. You have 60 to spend and you decrease it by $15 for each hat you buy till you save $7. This is it.
Answer:
63,029
Step-by-step explanation:
60,000+3,000=63,000
63,000+20=63,020
63,020+9=63,029
2x+6 is the base
Then the equation is logarithm of 144 on basis 2x + 6 = 2
Then [2x + 6]^2 = 144
Now expand the square binomial
4x^2 + 24x + 36 = 144
4x^2 + 24x + 36 - 144 = 0
4x^2 + 24x - 108 = 0
Divide by 4
x^2 + 6x - 27 = 0
Factor: (x + 9 ) (x - 3) = 0
x = -9 and x = 3
The only valid is x = 3, because x = -9 yields 2x + 6 = - 12 and the logarithm function cannot have negative basis.
Then the answer is x = 3.
Answer:
(4/x)-1
Step-by-step explanation:
The quotient of 4 and the number x means we are dividing 4 by x, so we get 4/x
Then we have the 'one less than' part, meaning we subtract one from (4/x), so we get (4/x)-1

Answer:
k=38
Step-by-step explanation:
add 22 to itself to cancel it out and add it to the 16 as well and you will get k
