Answer:

\frac{29}{35}

Step-by-step explanation:

So in order to add these two fractions they need to have the same denominator

  • So make them have the same denominator we need to find a common factor between the two numbers, 5 and 7
  • The first common factor between the two is 35
  • So we need to manipulate both fractions so both of their denominators are 35

In order to make \frac{2}{5} into a fraction with the denominator of 35, the denominator must be multiplied by 7. And whatever is done to the bottom also needs to be done to the top

  • We need to multiply \frac{2}{5} by \frac{7}{7} which then makes this fraction \frac{14}{35}

In order to make \frac{3}{7} into a fraction with the denominator of 35, the denominator must be multiplied by 5. And whatever is done to the bottom also needs to be done to the top

  • We need to multiply \frac{3}{7} by \frac{5}{5} which then makes this fraction \frac{15}{35}

Now that we have two fractions with the same denominator, we can add the fractions by adding their numerators: \frac{14}{35}+\frac{15}{35}=\frac{29}{35}

The measures of the angles of a triangle are 2x+10, 3x, and 8x-25 what is the triangle
umka2103 [35]

Answer:

40,45,95

Step-by-step explanation:

The sum of the angles of a triangle are 180

2x+10 + 3x + 8x-25 = 180

Combine like terms

13x - 15 = 180

Add 15 to each side

13x - 15+15 =180 +15

13x = 195

Divide by 13

13x/13 = 195/13

x =15

The angles are

2x+10 = 2(15)+10 = 30+10 = 40

3x = 3(15) = 45

8x-25 = 8(15) -25 = 120-25 = 95
