Make x the subject: a(x-b) = x

Mathematics
1 answer:
umka21 [38]3 years ago
5 0

Answer:

x = \frac{ab}{a-1}

Step-by-step explanation:

Given

a(x - b) = x ← distribute parenthesis on left side

ax - ab = x ( subtract x from both sides )

ax - x - ab = 0 ( add ab to both sides )

ax - x = ab ← factor out x from each term on the left side

x(a - 1) = ab ← divide both sides by a - 1

x = \frac{ab}{a-1}

The sum of 3 consecutive integers is 78. What is the integer closest to zero?
vova2212 [387]

Answer:

25

Step-by-step explanation:

Let n be the first integer.

Then the second integer will be (n + 1).

And the third will be (n + 2).

The sum is 78. Therefore:

n+(n+1)+(n+2)+78

Solve for n. Combine like terms:

3n+3=78

So:

3n=75

Therefore:

n=25

Therefore, the first integer is 25.

So our sequene is 25, 26, and 27.

The integer closest to zero will thus be 25.

The verticals of a right triangle are (0, -6), (6, -3), and (x, -6). Find the value of x.
Nataly [62]
(0,-6), (6, -3), and (6,-6)

If you plot them on a graph there are only two point options (in green and purple) since it's a right triangle but you have to use the one that has -6 as the y value
