Answer: 33 child tickets that were sold.
Step-by-step explanation:
Let x represent the number of child tickets that were sold.
Let y represent the number of adult tickets that were sold.
At the city museum, child admission is $5.40 and adult admission is $9.10. A total sales of $1079.10 was made on Monday. This means that
5.4x + 9.1y = 1079.1 - - - - - - - - - -1
On Monday, three times as many adult tickets as child tickets were sold. This means that
y = 3x
Substituting y = 3x into equation 1, it becomes
5.4x + 9.1 × 3x = 1079.1
5.4x + 27.3x = 1079.1
32.7x = 1079.1
x = 1079.1/32.7
x = 33
y = 3x = 3 × 33
y = 99
Answer:
60

Answer:
198 g
Step-by-step explanation:
Let y = the new weight
the healthy cub gains 7% of its newborn weight per day = 0.07 × 100 = 7 g
after d days
y = 100 + 7 d
after 14 days,
the new born will weigh = 100 + (7 × 14) = 100 + 98 = 198 g
Just use quizlet and you’ll get all the answers
Area=l*b=l*(l-2)=80(given)
so, l^2 - 2l =80
l^2 - 2l - 80=0
l=10 or -8
l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36
