Hamburgers cost $3 and hotdogs cost $2. The total cost of buying b hamburgers and d hotdogs can be expressed by C=3b+2d. How can
Temka [501]
C = 3b+2d is the same as 3b+2d = C

Let's isolate d. To do this, we first need to subtract 3b from both sides

3b+2d = C
3b+2d-3b = C-3b
2d = C-3b

Then divide both sides by 2

2d = C-3b
2d/2 = (C-3b)/2
d = (C-3b)/2

Take note of the parenthesis as they are very important. We want to divide ALL of C-3b over 2. We don't want to just divide -3b over 2.

The answer choices you have aren't 100% clear but I have a feeling your teacher meant to say d = (C-3b)/2 instead of d = C-3b/2 for choice A

If that assumption is correct, then the answer is choice A.

Given that 7 x − 2 y = 35 Find y when x = − 9
Sergio [31]

so x = minus 9

then

7 × (-9) - 2y = 35

-63 - 2y = 35

-2y = 35 plus 63

-2y = 98

- y = 49

y = -49

Will mark brainliest if correct
lord [1]

Answer:

mean =  \frac{9 + 4 + 4 + 1 + 0 + 6 + 4}{7}  =  \frac{28}{7}  = 4

mean \: deviation =  \frac{ |9 - 4| +  |4 - 4|  +  |4 - 4|   +  |1 - 4| +  |0 - 4| +  |6 - 4|   + |4 - 4| }{7}  =  \frac{5  + 0 + 0 + 3 + 4 + 2 + 0}{7}  =  \frac{14}{2}  = 7
