Which property states that if a = b and b = c, then a = c?

1 answer:

6 0

Transitive.

Associative is (a + b) + c = a + (b + c)

Commutative is a + b = b + a

Reflexive is a = a

Thus, transitive is the correct answer.

Hope this helps!

Answer:

x = -10/13

Step-by-step explanation:

10x + 7 = -3x - 3

Add 3x to both sides

10x + 3x + 7 = -3x + 3x - 3

13x + 7 = 0x - 3

13x + 7 = -3

Subtract 7 from both sides

13x + 7 - 7 = -3 - 7

13x + 0 = -10

13x = -10

Divide both sides by 13

13x ÷ 13 = -10 ÷ 13

1x = -10/13

x = -10/13

Can you guys help me? :-(

Answer:

$\frac{9}{10}$

Step-by-step explanation:

Find the LCD because like last time, you cannot add or subtract fractions with different denominators.

LCD = 10

Since the second fractions stayed at the same denominator, you will only have to multiply the first fraction.

$\frac{2 * 2}{5 * 2}$

$\frac{4}{10}$

$\frac{4 + 5}{10}$

$= \frac{9}{10}$

We can distribute the negative to get 8 + 6i + 2 - 7i, and we can simplify that to get 10 - i.
