Hey download photomath it works great u take a picture of your math problem and itll give u the steps n the answer
Fh. = 40h + 120, fh. = $200
200 = 40h + 120
200 - 120 = 40h
80 = 40h
80/40 = h
2 = h
h = 2 hours.
Answer:
the solution is (-4, 2)
Step-by-step explanation:
6x + 8y = -8
x + 4y = 4
... can be solved using elimination by addition and subtraction, among other methods. Multiply the second equation by -2 to obtain
6x + 8y = -8
-2x - 8y = -8
Combining these results in
4x = -16. Thus, x = -4.
Substituting -4 for x in x + 4y = 4 results in
-4 + 4y = 4, or 4y = 8, or y = 2
Then the solution is (-4, 2)
Answer:
B, D, C, A
Step-by-step explanation:
The question is asking to put the photographers into least to greast.
For the best case, I suggest you change them into decimals and put them in order.
Photgrapher A: 2/5 = 0.4 = 40%
Photographer B: 4% = 0.04 = 4%
Photographer C: 0.29 = 29%
Photographer D: 27/100 = 0.27 = 27%
Now put them into least to greatest.
Photographer B, Photographer D, Photographer C, And Photographer A
