Answer:
2
Step-by-step explanation:
2x + 4 = 8
subtract 4 from both sides
2x = 4
divide by 2
x = 2
Answer:
area of circle=π
452.1=3.14
452.1/3.14=
143.98=
=r
11.99=r
now ,
diameter=2r
=2*11.99
=23.98
Step-by-step explanation:
Step-by-step explanation:
9x+6+5x+90°= 180°
14x+96=180
14x=180-96
14x=84
x= 84/14
x=6
so, <A=5x=5(6)=30°
<B=9x+6=9(6)+6=54+6=60°
<C = 180-(30+60)=180-90=90°
Let the red beans be 5x and green beans be 9x
Then,
total beans = 5x + 9x =14x
∴ The fraction of beans that are red = No. of red beans / Total beans
= 5x/14x
= 5/14
Step-by-step explanation:
area = ( base 1 + base 2 ) ÷ 2 x height
50 = ( 10 + 15) ÷2 x height
50 ÷ 12.5 = height
height = 4
