The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50
Elimination method was used.
Step-by-step explanation:
Let,
Cost of one large pizza = x
Cost of one breadstick = y
According to given statement;
4x+y=34.46 Eqn 1
2x+y=18.48 Eqn 2
Subtracting Eqn 2 from Eqn 1
Dividing both sides by 2
Putting x=7.99 in Eqn 2
The cost of 1 large pizza is $7.99 and cost of one breadstick is $2.50
Elimination method was used.

Answer:
Arnett - red car
Bradley - gray car
Church - yellow car
Dawson - silver car
Step-by-step explanation:
1st clue - we know that Bradley and Church can't have the silver car.
2nd clue - we know that Dawson can't have the red or gray car.
3rd clue - we know that Dawson and Arnett can't have the yellow car.
Based on the 2nd and 3rd clue, we know Dawson has the silver car because he can't have the red, gray, or yellow car.
4th clue - we know Bradley can't have the red or yellow car.
That leaves us with the gray car for Bradley because he had lunch with the owner of the silver car (which i consider also a bright color but i don't know if that counts).
so far:
dawson - silver car
bradley - gray car
and we know arnett can't have the yellow car because the owner of hte yellow car thinks he got a better car with his car then dawson and arnett, which leaves us with the red car for arnett.
dawson - silver car
bradley - gray car
arnett - red car
by process of elimination, that means church has the yellow car.
arnett - red car
bradley - gray car
church - yellow car
dawson - silver car
X=ind tickets
y=coup. tickets x = 38 + y ← # of ticket equation
3x + 5y =730 ← $ of equation
3(38+y) + 5y = 730
114 + 3y + 5y = 730
114 + 8y =730
-114 = -114 → 8y =616 = y= 77 → x= 38 +y → x=38 + 77 → x =115
(115,77)
15 individual tickets and 77 couple tickets
Answer:
-203 is the answers for the question
Step-by-step explanation:
please give me brainlest
I only know 9) and 10) sorry but here they are:
9) x=16 because ...
3x+20=5x-12
(-3x) (-3x)
20=2x-12
(+12) (+12)
32 = 2x
(32/2) (2x/2)
16=x
10) x=46
angles in quadrilaterals add to 360’
So you do ...
360-134-134-46= 46
This is all I know sorry. Hope you find some more help :)
