Answer:
Option D
x+4x>55
Step-by-step explanation:
Let the age of Julio be x
The age of Julio's father will be 4x
The sum of their ages is
x+4x
The sum is no less than 55 to mean it's greater than 55 hence
x+4x>55
Answer:
Step-by-step explanation:
12 x + 4 y = 42 .............1
16 x + 8 y = 64 .............2
Eliminate y
multiply (1)by -2
Multiply (2) by 1
-24 x -8 y = -84
16 x 8 y = 64
Add the two equations
-8 x = -20
Answer:
1) one
2) zero
Step-by-step explanation:
e/sinE = g/sinG
10/sin64 = 9/sinG
sinG = 0.8089146417
G = 53.99
j/sinJ = k/sinK
3/sin129 = 8/sinK
sinK = 2.072389241
