Answer:
(2x+5)(x+4)
Step-by-step explanation:
After factoring we can find that it equals
(2x+5)(x+4)
Answer :
6. x=28
7.x =6
8. x =9
9. x =9
Step-by-step explanation:
6.
(x+2)/10 = 3
Cross multiply
x+2 = 10 ×3
x+2 =30
Collect like terms and simplify
x =30-2
x = 28
7.
8x +9 -5x= 27
Collect like terms and simplify
8x-5x =27-9
3x =18
Divide both sides of the equation by 3
3x/3 = 18/3
x = 6
8.
10x+8=8x+26
Collect like terms
10x-8x=26-8
2x = 18
Divide both sides of the equation by 2
2x/2 = 18/2
x = 9
9.
2(x-5)+4x=x+35
Use 2 to open the bracket
2 × x =2x
2×(-5) =-10
2x-10+4x =x+35
Collect like terms and simplify
2x+4x-x = 35+10
5x = 45
Divide both sides of the equation by 5
5x/5 = 45/5
x =9
Answer:
3x - 2 = 4x + 5
3x - 4x = 2 + 5 (move the numbers with the variable x to one side, and the normal numbers to the other side. Switch the signs of the numbers you move. 4x became -4x and -2 became 2.)
-x = 7 (simply add the numbers)
x = 7
15 machines * 15 minutes = 500
75 machines * x = 6000
by dividing both equations we have
(75*x)/(15*15) = 6000/500
solving for x
x = 36
it would take 36 min
