7
Half of 7 is 3.5
4-3.5=0.5
Answer:
Step-by-step explanation:
length * width * height = 1050 cubic ft
(10x + 5)* (2x -1) * (x +3) = 1050
(10x + 5 )(2x-1) = 10x*(2x - 1) + 5*(2x -1)
= 10x*2x - 10x*1 + 5*2x - 1*5
= 20x² - 10x + 10x - 5 = 20x² - 5
(10x + 5)(2x -1)(x+3) = (20x² -5) *(x + 3)
=20x²*(x +3) - 5*(x +3)
= 20x³ + 60x² - 5x - 15
20x³ + 60x² - 5x - 15 = 1050
20x³ + 60x² - 5x - 15 - 1050 = 0
20x³ + 60x² - 5x - 1065 = 0
By trial and error method , (x -3 ) is a factor
Synthetic method:
3 ( 20 60 -5 -1065
( 60 360 1065
20 120 355 0
20x² + 120x + 355 = 0
Divide the equation by 5
4x² + 24x + 71 = 0 . Solving this equation gives imaginary number. So, ignore these values.
So, value of x = 3
height = 3+ 3 = 6 ft
Length = 10*3 + 5 = 30 + 5 = 35ft
Width = 2x - 1 = 2*3 - 1 = 6 - 1 = 5 ft
Check: length * width * height = 35 * 5 * 6 = 1050 cubic ft
Answer:
71 -h
Step-by-step explanation:
The player had 71 -h hits in the rest of the games.
_____
In case you cannot write down this answer right away, you can figure it this way. Let r represent the hits the player got in the rest of the games. Then the player's total of hits for the season was ...
r + h = 71
Subtracting h from both sides of this equation tells us what r was:
r +h -h = 71 -h
r = 71 -h . . . . . . . hits in the rest of the games
The player had 71 -h hits in the rest of the season.
5x-3/2=3x+8
5x-1.6=3x+8 divide 3/2
5x=3x+9.5 add 1.6 to 8
2x=9.5 subtract 3x from 5x
2x/2=9.5/2 divide to isolate x
x=4.75
hope it helps!
