These are the ones that I could solve
Answer:
D
Step-by-step explanation:
all the options seems similar..but i can find the D more suitable
So Sally gets payed <span>$32,448 a year and gets paid the same amount each week. To figure how much she gets payed a week, divide her salary by 52 weeks since there are 52 weeks in a year. Then we divide how much she makes a week by 40 to see how much she gets payed an hour since she works 40 hours each week:
</span><span>32,448/52 = 624
624/40 = 15.6
Sally makes $15.60 an hour.
</span>
Infinitely many is the first one, because you can convert one equation into another one (3x-3y=-18---> x-y=-6, ---->y=x+6)
second one is one solution, because
y=-4x+11 and y=11+6x,--->-4x+11=11+6x, -4x-6x=0, x=0
third one
y =-2x+5 and y=-7-2x ,-2x+5=-7-2x, --->5=-7 false , no solutions
