Hi there!
Your question:
8.5 + 49(1-2.5k)=24.5
My answer:
8.5 + 4(1-2.5k) = 24.5 >>>>>>> first, you have to distribute
8.5 + 4 - 10k = 24.5 >>>>>>>> now, we are going to combine like terms.
12.5 - 10k = 24.5 >>>>>> now, we are going to subtract 12.5 on both sides
-10k = 12 >>>>>>>>> finally, divide -10 on both sides
k = -1.2
Hope this helps you!
The answer is the option D: D)none of the above.
The explanation is shown below:
By definition, a terminating decimal must have finite numbers of digits and it must be a rational number, which means that it can be written as a simple fraction whose numerator and denominator must be integers.
Keeping the information above on mind,you have that the option A does not have finite digits, and the options B and C can't be written as a simple fraction. Therefore, the answer is the option D.
Answer:
the answer is b
Step-by-step explanation:
(24)(.25)=6 dollars more per hour
24+6=30
If this is just factoring, x^2 + x - 90 turns into this:
(x - 9)(x + 10)
If your trying to solve for x, we take the factored expression and set it equal to 0.
(x - 9)(x + 10) = 0
Set each binomial into two equations.
x - 9 = 0 and x + 10 = 0
Solve for x and we get two answers.
x = 9
x = -10
