No they are not.
48/2 = 24, 60/3=20.
24/=20. (24 does not equal 20)
So you need to do substitution. First solve the easier equation for 1 variable.
x+y=-1 now subtract x to get y=-x-1. Then plug this into the top equation to get 2x+7(-x-1)=2. Next distribute to get 2x+-7x-7=2. Now combine like terms to get -5x=9 so x=-5/9. Now you have to plug this back into the original equation to get y. 2(-5/9)+7y=2, so -10/9 +7y=2. No move terms around to get 7y=28/9 then divide by 7 to get y= 4/9
The triangle BAC has two known measurements 30 and 90 so add those together and subtract by 180
30 + 90 = 120
180 - 120 = 60°
Answer:
where are the statements...
mention the statements first
4500 divided by 75 is 60 so 1% = 60 undergraduates so 60 times 100 = 100% which is 6000 undergraduates.
