Answer:
a
Step-by-step explanation:
it is a because the shape is moving to the side
77/5=99/x
77x=5*99
77x=495
x=495/77
x=6.4
she needs to study 6.4 hrs to get 99
45/X + 63/X= 108/X = Y, X= 108 divided by 2 = y, y=54
J ---- P --- K
JP = 2x
PK = 7x
JK = 27
2x + 7x = 27
9x = 27
x = 27/9
x = 3
The value of P is 3.
JP = 2x = 2(3) = 6
PK = 7x = 7(3) = 21
