X=price of one jumbo popcorn
y=price of one chocolate chip cookies
$5.00=$5.00(100 cts / $)=500 cts
$6.00=$6.00(100 cts / $)=600 cts
We suggest this system of equations:
x+2y=500
x+4y=600
we solve this system of equations by reduction method.
-(x+2y=500)
x+4y=600
----------------------
2y=100 ⇒ y=100/2=50
x+2y=500
x+2(50)=500
x+100=500
x=500-100
x=400
solution: one chocolate chip cookie cost 50 cts.
Answer:
Right angles is 90° so 90°+30°=120°.A straight line is 180°. So you do 180°-120° which is 60. So A=60°
This is the answer 104.4285714285714
The quotient of 78,600 and 12 is 6,550
I'll do one, you can use it as a basis for your answer.
Subtract 6 from both sides to get X by itself.
Now we divide by 7 for both sides as well.
Now we find the square root of 1 to figure out X.
Therefore, X=1.
my first answer in about a month. hope this helped.
