Me which answer correctly inserts grouping symbols so this expression has a value of 25? 12 - 7 + 2 • 4 + 6 a. (12 - 7) + 2 • (4 + 6) b. (12 - 7 + 2) • (4 + 6) c. (12 - 7) + (2 • 4 + 6) d. 12 - (7 + 2) • (4 + 6)

Its A

(12 - 7) + 2 • (4 + 6)

= 5 + 2 . 10

= 5 + 20

= 25

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
