Answer:
-6
Step-by-step explanation:
Are you sure that z + 2+ z is correct? x and y do not appear here.
z + 2+ z simplifies to 2z + 2, and so, if z = -4, z + 2+ z has the value
2(-4) + 2, or -6.
Answer: 7 inches
Step-by-step explanation:
4 times 1 3/4 is 7
X=2
subtract 5x on both sides
-2x=-4
divide by -1 on both sides
2x=4
divide by 2 on both sides
x= 2
I guess itz B because with the rest, a number can be added to get exactly 50. Example C. y= 50x. x could be 1 which is still 50 and D. y=50-x and x could be 0 which is still 50 whiles A. y=50 remains 50
