It’s 32!

5a = 5 x 4 = 20
2b = 2 x - 6 = -12

20 - -12 = 32 ( two negatives make a positive!)

Nonamiya [84]

Answer:

49.12 square inches

Step-by-step explanation:

Area of a circle = Pi x r^2

= 3.14 x 16

= 50.24

Half the circle = 25.12 squared inches

Area of a triangle = base x height /2

= 6 x 8 /2

= 24

25.12 + 24 = 49.12 square inches

20x+3=17 help please
jeyben [28]
The objective is to get the variable (x) alone. To do this start be subtracting 3. What you do to one side you have to do to the other so you have to subtract three from the other side of the equal sign as well. So now you have:
20x= 17-3 subtract the 3 to get 20x=14
Now because the 20 is attached to the x In order to get the x alone you have to divide by 20:
20x/20. =14/20 divide 14 by 20

X=.7 or x=7/10
