Answer:

k=57

Opposite angles are equal

\\ \rm\longmapsto -k+15=k-99

\\ \rm\longmapsto -k-k=-99-15

\\ \rm\longmapsto -2k=-114

\\ \rm\longmapsto 2k=114

\\ \rm\longmapsto k=\dfrac{114}{2}

\\ \rm\longmapsto k=57

Advocard [28]

9514 1404 393

Answer:

  a, c, b

Step-by-step explanation:

Collect terms, subtract the constant, divide by the y-coefficient.

(a) 4y + (y - 1) = 29   ⇒   y = 6

(c) (2y + 3) - 4 = 9​   ⇒   y = 5

(b) 4y - y + 1 = 13   ⇒   y = 4 . . . . . this equation is not what you have written

<em>Additional comment</em>

The second equation suffers from a typo, so your answer may vary.

Jasmine has a bag of 48 peanuts. She eats 3/4 of the bag during the baseball game. How many peanuts does she have left? Explain
rosijanka [135]

Answer:

12

Step-by-step explanation:

If she eats 3/4 of the bag, that means she has 1-3/4 = 4/4 -3/4 = 1/4 of the bag left

The bag has 48 nuts. Take the number of nuts times the 1/4 she has left

48 * 1/4 = 12

She has 12 nuts left
