If p is the price of a bag of popcorn and d is the price of a drink
2p + 3d = 18.25 Mohamed’s order
4p + 2d = 27.50 Miguel’s order
If we double the first equation
4p + 6d = 36.50
Now subtract the second equation (find the difference between them)
4d = 9.00
d = 2.25
Substitute in the first equation
2p + 3 x 2.25 = 18.25
2p = 18.25 - 6.75 = 11.50
p = 11.50 / 2 = 5.75
Popcorn was $5.75 a bag and drinks were $2.25 each
Answer:
5120
Step-by-step explanation:
divide the entire group into 10 groups where each group has a man and his wife.
number of ways of selecting 9 groups is 10C9 which equals 10 ways
the number of ways selecting 1 person from a group is 2C1 =2 .
So that means the number of ways of selecting 1 person from 9 groups is 2^9=512
number of ways to form the committee is 10*2^9=5120
Can I have brainliest since u did t put a picture :)
4 |x = 5| = 20
First, divide both sides by 4. / Your problem should look like:
Second, simplify

to 5. / Your problem should look like:
Third, break the problem into 2 equations. / x + 5 = 5 and -(x + 5) = 5
Fourth, solve x + 5 = 5. /
Cancel 5 on both sides. /
Fifth, solve -(x + 5) = 5 /
Simplify brackets /

Add 5 to both sides /

Add 5 + 5 /

Multiply both sides by -1 /

x = -10
Sixth, collect the solutions to the problems. / Your problem should look like:

Answer:
x = -10, 0
20000 times a million thousand it equal 20000000000
