Hope this helps..
Step-by-step explanation:
Given equations
2x + 5y = 6 .......i)
2x = 10 - 3y...... II)
Putting 2x = 10 - 3y in equation i
10 - 3y + 5y = 6
2y = 6 - 10
2y = - 4
y = - 4 / 2
y = - 2
Now putting y = - 2 in equation ii
2x = 10 - 3 * ( - 2)
2x = 10 + 6
2x = 16
x = 16 / 2
x = 8
So x = 8 and y = - 2
Hope it will help :)❤
Most of them are +10 because for example 8+10 is 18
Answer:
Area: 28.26ft², Circumference: 18.84ft
Step-by-step explanation:
Area of a circle: πr²
Circumference of a circle: πd (or 2πr)
Since the diameter is 6ft, then the radius is half of that, which is 3ft. This means that our area is:
πr²
π(3)²
π(9)
9π
9(3.14)
28.26ft²
Our circumference is:
πd
π(6)
6π
6(3.14)
18.84 ft
