No, they are not equivalent because if you distribute the -0.5 in the expression -0.5(3x+5) you will get -1.5x-2.5 which is not the same as -1.5+2.5
Theoretical probablity=desiredoutcomes/totalpossibleoutcomes
desired=number of white marbles=20
total possible=red+blue+white=30+50+20=100
so theoretical probablity=20/100=2/10=0.2=20%
Answer:
0.45pound
Step-by-step explanation:
Since it's given Maggi buys 3/4 pounds of blueberry,it's means 3/4*1 .i.e. 0.75 pound and he uses 3/5 of 0.75 pound then it would be 3/5*0.75 .ie 0.45 pound
X would equal 70°.
For every triangle, all interior angles add up to 180°. This means that we can add together 42 and 68 to get 110°. Because the sum of all interior angles in a triangle must be 180°, we subtract 110 from 180 to see how much more we need, which gets us 70°.
I hope this helps!
