Answer:
n= -52/7
Step-by-step explanation:
7(n+8)=4
(7×n)+ (7×8)=4
7n +56=4
7n +56-56=4-56
7n+0= -52
7n=-52
7n/7= -52/7
n= -52/7
Answer:
47.9 gm
Step-by-step explanation:
According to the scenario, calculation of the given data are as follows,
Total butter took = 54.8 gm
Extra butter quantity = 6.9g
So, we can calculate the exact quantity of butter needed by using following formula,
Exact butter needed = Total butter - Extra butter quantity
By putting the value, we get
Exact butter needed = 54.8 gm - 6.9gm
= 47.9 gm
Hence, he need 47.9gm butter.
That is the combination of 10 over 3, which is calculated as the quotient of factorials:
n!/k!(n-k)!
where n = 10 and k = 3:
= 10!/3!(10 - 3)!
= 10!/3!*7!
= (10*9*8)/(3*2*1)
= 720/6
= 120
therefore there a re 120 possible different groups
Answer:
320
Step-by-step explanation:
multiply by 10 and get rid of the decimal
<em>Note: I am assuming the first equation is:</em>
<em>x+y = 3</em>
Answer:
The solution to the system of equations is:
(x, y) = (-2, 36)
Therefore, the x-coordinate of the solution of the system
x = -2
Step-by-step explanation:
Given the system of equations
subtracting the equations
solve -2y for y
Divide both sides by -2
For x+y=34 plug in y = 36
Subtract 36 from both sides
Simplify
Thus, the solution to the system of equations is:
(x, y) = (-2, 36)
Therefore, the x-coordinate of the solution of the system
x = -2
