Please help me. -1/15 + (-3/5)

Mathematics
1 answer:
goblinko [34]3 years ago
8 0

Answer:

-\frac{2}{3}

Step-by-step explanation:

-1/5 + (-3/5)

Least common multiple of 15 and 5 is 15. Convert -\frac{1}{15} and \frac{3}{5} to fraction with a denominator of 15.

-\frac{1}{15} -\frac{9}{15}

Since -\frac{1}{15}  and \frac{9}{15} have the same denominator, subtract them by subtracting the numerators.

\frac{-1-9}{15}

Subtract 9 from -1 to get -10

\frac{-10}{15}

Reduce the fraction \frac{-10}{15} to lowest terms

-\frac{2}{3}

have a nice day!

Calculate the value of b.<br>(b-15)<br>3b°<br>(2b + 45°<br>Diagram not drawn accurately​
e-lub [12.9K]

Answer:

b = 30

Step-by-step explanation:

The sum of the 2 angles above the line will equal the angle below the line

3b + b - 15 = 2b + 45

4b - 15 = 2b + 45 ( subtract 2b from both sides )

2b - 15 = 45 ( add 15 to both sides )

2b = 60 ( divide both sides by 2 )

b = 30
