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.
Answer:
Each pizza costs $12.
Each drink costs $2.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the cost of each pizza.
y is the cost of each drinks.
The Talbot family got 2 pizzas and 4 drinks for $32.
This means that
The Martinez family got 3 pizzas and 8 drinks for $52.
This means that
Using the addition method, multiplying the first equation by -2.
-4x - 8y = -64
3x + 8y = 52
-4x + 3x - 8y + 8y = -64 + 52
-x = -12
x = 12
Each pizza costs $12.
2x + 4y = 32
2x + 4y = 32
4y = 32 - 2x
4y = 32 - 2*12
4y = 8
y = 2
Each drink costs $2.
