1. 4x(-4)x(-5)= 80
2. 5x(-4)-2x(-5) = -10
3. [-4x(-5)]x2= 40
4. -4x2x(-5)= -13
5. 4x(-4)x(-5)x2= 160
6. 3x(-4)x(-5)-5x(-5)= 85
7. -4x(-5)÷2= 10
8. 3x(-4)x2÷4= -6
9. 5x(-5)-(-4)x2= -17

I wasn't sure what the space were so I thought they were mistakes and did the problems as if they were not there but if they were meant to be there then tell me what they were meant to be and I will fix it (If there is no spaces on yours then you are probably thinking that I am going crazy)

4 - 2(x-4)/ 3= 3(2x+5)/2 linear equation in one variable no spamms❌❌❌❌

xxMikexx [17]

Step-by-step explanation:

4-2x+8/3 = 6x+15/2

12-2x+8/3= 6x+15/2 ( taken LCM. of 1,3,3 in LHS)

20-2x/3=6x+15/2

Do cross multiplication

2(20-2x) = 3(6x+15)

40-4x=18x+45

-4x-18x=45+40

-22x= 85

-x= 85/22

x= - 3.86..

Using 5 letters followed by 2 digits, how many passwords are possible?

Deffense [45]

Since there is no condition whatsoever for this arrangement, I can consider the 2 digits and the 5 letters as 7 different objects.

Total permutation (with no repetition):
7 chosen among 7 , that is 7 ! = 5040 arrangements

Total permutation (WITH REPERTITION):

7⁷ = 823 543
