Answer:

10a and 5a+2a+3a

Step-by-step explanation:

6a + 4a = 10a

10a = 10a

9a is not equal to 10a

10+a is not equal to 10a

5a+2a+3a = 10a

6a - 4a is not equal to 10a

a^10 is not equal to 10a

Hope this helps! :)

(7x-5)+(3x-15)=180°

10x-20=180

10x=200

x=20

(3x-15) + E = 180

3(20)-15 + E = 180

45 + E = 180

E = 135°

FG = EH = 2(y+1)

Answer:

2.- 100

Step-by-step explanation 1:

$\frac{7}{25} + \frac{3}{4} = \frac{28}{100} + \frac{75}{100} = \frac{103}{100}$

↑ As we can see, the only common multiple between 4 and 25 that is given to is 100.

Step-by-step explanation 2:

$\frac{(7 * 4) + (3 * 25)}{4 * 25} = \frac{28 * 75}{100} = \frac{103}{100}$

↑ Another way of knowing the answer is by using a fraction solving method. As we can see, the denominator is once again 100.

Hope it helped,
