Answer:
The answer is 18x.
Step-by-step explanation:
2x times 9 is 18x because when you multiply 9 times 2, you get 18 and the x carries over.
Start with 6.106. move the decimal over 7 spots to the right.
Your answer will be 61,060,000.
Answer:
EASY DUBS:
Step-by-step explanation:
2*x-((1/4)*y) = 1 // - 1
2*x-((1/4)*y)-1 = 0
2*x+(-1/4)*y-1 = 0
2*x-1/4*y-1 = 0 // + -1/4*y-1
2*x = -(-1/4*y-1) // : 2
x = (-(-1/4*y-1))/2
x = (1-(-1/4*y))/2
x = (1-(-1/4*y))/2
The surface area of the balloon is 249 in².
<h3>What is the surface area of the balloon ?</h3>
A balloon has the shape of a sphere. The distance round the sphere is equal to the circumference of the sphere.
Circumference of the sphere = 2πr
Where:
- r = radius
- π = pi = 22 / 7
Radius - circumference / 2π
28 / ( 2 x 22/7) = 4.45 inches
Surface area of a sphere = 4πr²
4 x 22/7 x 4.45² = 249 in²

X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8
