Answer:
x=80
Step-by-step explanation:
The sum of interior angles in a quadrilateral is 360°
the square represents a right angle= 90 degrees
124+66+90=280
360-280=80
x=80
Answer:
Step-by-step explanation:
Angle 1 = 1, 3, 5, 7
Angle 3 = 1, 3, 5, 7
Angle 4 = 2, 4, 6, 8
Pretty much just look at the congruent symbols and you can figure it out.
X = nine. Seventy five / 9.75!
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.
