Looks good for high school math make sure the teacher sees you're work clearly and know what the numbers are overall you should be good
equation for first figure=2x+y=2
equation for second figure= 4x-y=8
(use formula x/a+y/b=1)
where, a=x component and b= y component..
Answer:

.
voters registered as Democrats 
voters registered as Republicans 
voters registered as Green party 

Probability that first call will be to Democrats

Probability that first call will be to Republican

probability that the first call will be to either a Democrat or a Republican



Hence the probability that the first call will be to either a Democrat or a Republican is 
Answer:
$1.25.
Step-by-step explanation:
We have been given that at a football game Jasmine bought a soft pretzel for $2.25 in a bottle of water for $1.50 she paid with a $5 bill.
First of all let us find how much Jasmine spent on soft pretzel and water bottle by adding the cost of both items.


To find the amount that Jasmine will get as a change we will subtract the amount spent on both items from 5.

Therefore, Jasmine will get $1.25 back as change.
