You would need to make them eliminate so I would multiply the entire first one by 2.5 to make the X's cancel out. So you would end up with -5X+7.5Y=17.5. The X's would cancel and you would be left with 15.5Y=15.5. So Y=1. Then replace Y into one of the equations. I'm going to use the top again. -2X+3(1)=7. Subtract 3 from both sides to get -2x=4. Divide both sides by negative 2 to get X=-2. So the solution would be (-2,1)
Answer:
0.43
Step-by-step explanation:
3.84/8= 0.43
Answer:
k=70
Step-by-step explanation:
two ways to do this
the sum of k+110 has to equal 180, so k=70
52+58+k has to equal 180, so k=70
<span>you have to take arctan(0) to find the value of theta.
tan^-1 (x)=theta </span>
For this, look at the 6th digit (hundred-thousands). If that digit is more than or equal to 5, then the next digit is rounded up. Since it is, the answer becomes 35,000,000.
Answer: 35,000,000
