Let, d be the price of drink and
p be the price of a bag of popcorn
the system of equations is:
5d+2p= 38.75
3d+4p= 37.25
-3(5d+2p)= -3·38.75 multiply both sides by -3
5(3d+4p)=5·37.25 multiply both sides by 5
Solve
-15d -6p = -116.25
15d+20p=186.25 +
--------------------------------
0 +14p = 70
14p=70
p=70/14=5
one bag of popcorn is $5
(8^-3)^-2 (8^8) = 8^n
8^6 * 8^8 = 8^n
8^14 = 8^n
n=14
Answer:
c= -6
Step-by-step explanation:
1) expand the equation to -8c-18=-3c+12
2) add 18 to both sides which then makes it -8c=-3c+30
3) add 3c to both sides which makes it -5c=30
4) then divide by -5 which makes it c=-6
Answer:
6 degrees Celsius
Step-by-step explanation:
It started at 2 degrees Celsius below zero. The next day, it dropped to 12 degrees Celsius below zero. The next day, it rose to 7 degrees below zero. The next day, it increased to 6 degrees ABOVE zero. -7+13=6
Answer:
y=x+12
Step-by-step explanation:
Well the slope is -4/-4 =1
We plug it into the formula, y=mx+b, but m=1
So it is y=1x+b
We know the points, so we plug y and x in which is:
-4=-4*4+b
-4=-16+b
b=12
So the point slope form of that is y=x+12
