Step-by-step explanation:
Firstly, you have yo multiply out the first bracket by multiplying (2x - 5) by 4. The equation would then look like:
8x - 20 = 5x - 20 + 3x
Then you have to put normal numbers on one side and x-terms on the other. It would look like:
-20 + 20 = 5x + 3x - 8x
Then you should solve the additions and subtractions
0 = 0x
Since ANY number multiplied by 0 is zero, your equation has infinite solutions.
hello :
<span>(-101)+102+(-103)+104+...+(-199)+200
=( </span>(-101)+(-103) +....+ (-199) ) +( (102) + ( 104) +....+(200))
let : A = ( (-101)+(-103) +....+ (-199) )
B = ( (102) + ( 104) +....+(200))
note : the sum n term of arithemtic sequence
S= n/2(u1 + un)
un = u1 +(n-1) d u1 : the first term d : the common diference
in A : u1= -101 d = -2 n = 49...
in B : u1 =102 d=2 n= 49
A = 49/2(-101-199) =-7350
B=49/2(102+200)=4949
(-101)+102+(-103)+104+...+(-199)+200 = A+B =-2401

Answer:
A has 77 grams and B has 12 grams.
Step-by-step explanation:
In order to find the amount of fat in both, we need to set up two equations in standard form. First, we can set up one comparing the two amounts and solve for the constant.
A = 6B + 5
A - 6B = 5
Now we can create one using the difference of the two.
A - B = 65
To solve, we now multiply the second equation by -1 and solve for B.
A - 6B = 5
-A + B = -65
----------------
-5B = -60
B = 12
Knowing this we can plug into the equation and find the value of A.
A - B = 65
A - 12 = 65
A = 77
