35. You have to plug in all the numbers to the matching variables and solve.

The answer would be 35 

u multiply  the 3 and 3 then multiply the 2 then u take the -2 and then u multiply to get the -6 . then do the same for the other one . then u get 18 +6+6+5=35 

the subtraction signs turn to plus.

D.

If Tony and Michael ate 26 you take that away from 60 which equals 34.

           26-60=34

Can someone help me PLZ! I keep posting the same question and no ones helping me :((((((((((((
kipiarov [429]

Answer:

Multiply x + y = 3 by 3 and add it to -3x - 2y = -7

Step-by-step explanation:

When using elimination to solve a system of equations, you multiply one equation by some number. The reason for doing this is that when you add it to the second equation, you want one variable to cancel out. When one variable cancels out (in this case x), you can solve for the other variable (in this case y). I will show this:

3(x + y = 3) = 3x + 3y = 9

   3x +  3y =  9

+ -3x + -2y = -7

---------------------------

              y  = 2

Now, knowing that y = 2, you can substitute y=2 into either equation to solve for x.

-3x - 2(2) = -7

-3x -4 = -7

-3x = -3

x = 1 | to double check (1, 2) as your answer plug these values into both equations

Finding this solution would not have been possible if not for cancelling out the x's above. The other three are wrong because none of the other options cancels out one of the variables.

What's the pattern for 2,4,7,9
Semenov [28]

Answer:

The pattern is this: I create a function p(x) such that

p(1)=1

p(2)=1

p(3)=3

p(4)=4

p(5)=6

p(6)=7

p(7)=9

Therefore, trivially evaluating at x=8 gives:

p(8)= 420+(cos(15))^3 -(arccsc(0.304))^(e^56) + zeta(2)

Ok, I know this isn’t what you were looking for. Be careful, you must specify what type of pattern is needed, because the above satisfies the given constraints.
