Step-by-step explanation:
53.56 / 1.3 = 41.2
Answer:
Step-by-step explanation:
16. 180=8x+2x
x=10°
17a. 180=(180-126)+2x+(180-6x)
x=14°
17b. 180=4x+x+65
x=23°
Answer:
(2,9)
Step-by-step explanation:
To do this you have to solve one of the equations for a variable.
-x+y=7
2x+3y=31
Because the first equation doesn't have any numbers attached to the variables I decided to solve for the y in that equation.
-x+y=7
y=x+7
With this now one would have to plug this into the second equations:
2x+3(x+7)=31
Use the distributive property.
2x+3x+21=31
simplify.
5x+21=31
Isolate the x.
-21 -21
5x=10
solve for the x.
x=2
Plug the x into one of the equations and solve for y.
-x+y=7
-2+y=7
isolate the y.
+2 +2
y=9
This is the point of solution.
Answer:
Step-by-step explanation:
square root of 15 is 3.8=irrational
square root of 21 is 4.58=irrational
square root of -9 is doesn't have a real square root
square root of 14 is 3.7 =irrational
