The answer is 68 because if it rose between the times it would mean you minus 7 from 75
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.
2.8a^2=55
a^2=55/2.8
a= square root of 55/2.8
Answer:
1.89x + 5.19y = 31.62.
Step-by-step explanation:
Let the pagke of hot dags be x
Let the pakage of hamburgers be y
Now they total up tp 8 packages.
xEliminate the cost
x+y=8
y=8-x
Cost of hotdogs = $1.89
Cost of hamburgers = $5.19
1.89x+5.19y=31.62
1.89x+5.19(8-x)=31.62
1.89x+41.52-5.19=31.62
-3.3x=--9.9
x=3
y=8-3
y=5
