Well first you find the common denominatior of 1/7 and 4/9 which is 63 so then you see how many times does 7 go into 63 so this is part where you multiply 7 and 9 which gives you 63 and then you do how many times 9 go into 63 which is 7 so then you will take 7 times the 4 which is 28 so now your fractions should be 9/63 and 28/63 then now your next step is to add the 9 and 28 which is now 37/63 and you ask yourself and you divide that by any number to get a smaller number which is no so that is your answer
Answer:
a
Step-by-step explanation:
because they are vertical angles they are equal to each other so we write the equation 132=5x+7
step 1 subtract each side by 7
125=5x
step 2 divide each side by 5
x=25
She can add 35 and 9 which equals 44
3. r^2 + 2r - 35 4. a^2- 11a + 28
(r + 7)(r - 5) (a - 7)(a - 4)
5. m^2 - 6m - 7 6. m^2 - m - 2
(m + 1)(m - 7) (m - 2)(m + 1)
7. n^2 - 4n + 3 8. b^2 - 4b - 5
(n - 3)(n - 1) (b - 5)(b + 1)
