Answer:
25 grams
Step-by-step explanation:
Good effort, but that's not quite right.
Let's call the daily amount of fiber needed x.
One serving of oatmeal provides 16% of the daily amount, or 0.16 x.
The rest of the daily amount is 21 grams.
Together, they add up to the total daily fiber:
0.16 x + 21 = x
Solving for x:
21 = 0.84 x
x = 25
You need 25 grams of fiber daily.
Let's check our answer. 16% of 25 is 4. 4 plus 21 equals 25. So it checks out.
Answer:
B
Step-by-step explanation:
The answer is: " 8 " .

Explanation:
________________________________
Let "x" represent the "original number".
2(x - 3) = 6 + (1/2)x ; Solve for "x" ;
______________________________________
Multiple the ENTIRE EQUATION (both sides) by "2" ; to get rid of the fraction:
2*{2(x - 3) = 6 + (1/2)x} ;
to get:
4(x - 3) = 12 + x ;
___________________________
Let us expand the "left-hand side" of the equation:
_____________________________________________
Note the "distributive property of multiplication" :
_____________________________________________
a(b - c) = ab - ac ;
a(b +c) = ab + ac ;
______________________________________________
So; "4(x - 3)" = 4*x - 4*3 = 4x - 12 ;
______________________________________________
Rewrite the equation:
_______________________________________________
4x - 12 = 12 + x ;
Subtract "x" from EACH side of the equation; and Add "12" to EACH SIDE OF THE EQUATION;
______________________________________________
4x - 12 - x + 12 = 12 + x - x + 12 ;
to get:
______________________________________________
3x = 24 ;
_____________________________________________
Now, divide EACH side of the equation by "3" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_____________________________________________
3x/3 = 24/3 ;
_____________________________________________
x = 8 .
_____________________________________________
Like terms are terms that have the same variable no matter the coefficient value such as a negative or positive coefficient (number right to left of the variable aka the letter representing an unknown amount of value).
A. 8n : - 4n becuase the have the same variable (N)
B. - 2d: D because they have the same variable and even if d has no coefficient, it still has value, variables with no coefficient always equal 1 no matter the circumstances
C. - b: 17b and -3b2 because they both have the same variable eliminating the coefficients being two different types of numbers (positive and negative). The expressions have to have the same variable.
D: 4y², -3y2,4y, and 4 to the second power. This is because they all have the same variable.
E. 6x2y: 3xy because the variable are specifially xy and they must be in order to be like terms.
abc: all because they have all the letters but are just in different orders of variables. (thats all)
