Answer:
Cora's spend will be = $ 16.66
Step-by-step explanation:
Let y be the amount Ben spent
As Ava spent three times Ben will be 3y and half as much Cora(2y)
so the equation becomes
y + 2y + 3y = 50
6y = 50
y = 50/6
y = 8.33
So Cora's spend will be : 2y = 2(8.33) = 16.66 units currency
Note: if currency is in $
Then Cora's spend will be = $ 16.66
It rotates 180 degrees because its like 90 +90+180

4.12 rounded to the nearest tenth is 4.1
Answer:
x > 
Step-by-step explanation:

Add 3 and 1 to get 4.

Use the distributive property to multiply 5 by 9−x.

Subtract 45/5 from both sides.

Since 44/4 and 45/4 have the same denominator, subtract them by subtracting their numerators.

Multiply both sides by -4/5, the reciprocal of -5/4. Since -5/4 is negative, the inequality direction is changed.

Multiply -1/4 times -4/5 by multiplying numerator times numerator and denominator times denominator.
