Solve for c. a(c−b)=da(c−b)=d c=d − abbc=d − abb c=ab − dac=ab − da c=d + abac=d + aba c=d − aba
Contact [7]

For this case we have the following equation:

a (c - b) = d

We want to solve the equation for the letter c.

To do this, we apply the distributive property:

ac-ab = d

Then, applying addition property of equality we have:

ac = d + ab

Then applying division property of equality we have:

c = \frac {d + ab} {a}

Answer:

The value of c is:

c = \frac {d + ab} {a}

The bill from your plumber was 134. The cost of labor was 32 per hour. The cost of materials was 46. How many hours did the plum

2.75 hours.

The equation would be 32x + 46 = 134. So we subtract 46 from 134 and get 88. Now we have to divide that by 32 to get the total of 2.75 hours

The perimeters of the triangles shown are equal.Find the side length of each triangle.
Anna11 [10]
I’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54
