1.
( x - 5 ) / x - 1 = ( x + 3 ) / x / · x ( we will multiply both sides by x )
x - 5 - x = x + 3
- x = 3 + 8
- x = 8
x = - 8
Answer: D ) 8
2.
2/(8 x²) = 1/ 8 x / · x
2 / 8 x = 1 / 8
8 x = 16
x = 16 : 8
x = 2
Answer: D ) 2
3.
( x + 4 )/ x + 1 = ( x + 6 ) / x / · x
x + 4 + x = x + 6
x = 6 - 4
x = 2
Answer: B ) 2
4.
1 / 6 = 3 / ( x + 12 )
x + 12 = 18
x = 18 - 12
x = 6
Answer: A ) 6
He bought 19/24 pounds of grapes.
You need to find the common denominators then add.
3/8 = 9/24 - Red grapes
5/12 = 10/24 - Green grapes
10/24 + 9/24 = 19/24.
Therefore, he bought 19/24 pounds of grapes.
Hope this helped! :-)
Answer:
58°
Step-by-step explanation:
65°+57°=122°
180°-122°=58°
Answer:
The force on the book is 250N.
Step-by-step explanation:
Newton's second law states that the equation for the force is:
In which m is the mass, in kilograms, and a is the acceleration, in m/s². F is the force measured in N.
In this question:
So
The force on the book is 250N.
