Answer:
X= -9
Y=7
Z=119
X=-70
Y=0.8
z=4.667
Step-by-step explanation:
X=-18-6= -24/3= -9
Y=24+11/5= 35/5= 7
Z=10+7=17*7=119
X=-2-5=-7*10=-70
Y=19-7=12/15=0.8
Z=-2+4=2*7=14/3=4.667
Its 89 because 9 times 2 is 81 and 10 times 2 is 100 there nothing to multiple 2 by something to get 89
The best thing to do us to find the difference between $150 and $100. The difference is $50. You've then got to divide $150/$50 and thus gives you 3.333, therefore, the percentage decrease is 33%
Hope this helps :)
