Answer:
$6
Step-by-step explanation:
Set up a system of equations where b is the cost of a book and m is the cost of a movie:
9b + 5m = 124
4b + 21m = 318
Solve by elimination by multiplying the top equation by -21 and the bottom equation by 5:
-189b - 105m = -2604
20b + 105m = 1590
Add the equations together, then solve for b:
-169b = -1014
b = 6
So, the cost of a book is $6
Answer:
The equation has no solution
Step-by-step explanation:
Since the left side is always > 0, the equation has no solution.
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)
Answer:
Yes, he can buy 8 donuts and 4 energy drinks.
Step-by-step explanation:
If Tension is able to buy 8 donuts and 4 energy drinks, then both inequalities would be valid when we use these numbers as inputs. Let's check each expression at a time:
The first one is valid, since 14 is less than 25. Let's check the second one.
The second one is also valid.
Since both expressions are valid, Tension can buy 8 donuts and 4 energy drinks and achieve his goal of having a caloric surplus of at least 1000 cal.
