Answer:
C. 20(1/2)
Step-by-step explanation:
Let's find the value of the expression before looking for the nearest estimate
(19 4/5) (4/6) = 19 *(4/5)(4/6)
(19 4/5) (4/6) = 19(16/30)
(19 4/5) (4/6) = 19(8/15)
(19 4/5) (4/6) = (19*8)/15
(19 4/5) (4/6) = 152/15
(19 4/5) (4/6) = 10(2/15)
A. 16(1/3) =5.33
B. 19(2/3) = 12.667
C. 20(1/2) = 10
D. 20(1)= 20
The nearest to the expression is C. 20(1/2)

Step-by-step explanation:
if the x value doesnt repeat then it is
<em>Answer:</em>
47/48
<em>Explanation:</em>
Since 5 7/8 is so close to 6, it is easier to work this problem by considering the difference.
The serving size is 1/6 of the total amount, so you want to find ...
... (5 7/8) × (1/6)
Following the observation above, we can compute it as ...
... (6 - 1/8) × (1/6) = (6/6) - (1/8)×(1/6)
... = 1 - 1/48
... = <em>47/48</em>
Substitute the numbers in place of the variables. (5)-8(-2)—> 5+16–>21. Answer is 21. Can I get brainliest?
5sqrt(x+7)=-10
Dividing both sides by 5:
5sqrt(x+7)/5=-10/5
sqrt(x+7)=-2
Squaring both sides of the equation:
[sqrt(x+7)]^2=(-2)^2
x+7=4
x+7-7=4-7
x=-3
Replacing in the original equation:
5sqrt(x+7)=-10
5sqrt(-3+7)=-10
5sqrt(4)=-10
5(2)=-10
10=-10 It's not equal, then x=-3 is an extraneous solution
