Step-by-step explanation:
x+y=7 _ eqn1
x-y=3_ eqn2
add eqn1 and eqn2
x+y=7
+ x-y=3
= 2x= 10
x=5
x+y=7
5+y=7
y=7-5
y=2 proved
Answer:
1. Alissa can conclude that there are fewer students at her school that want to visit Japan (7) than Australia (13)
I'm not sure about the 2nd question so you can use it if you want or just wait if someone else gives a different answer

25 - 13 = 12 pets that have a home
Pets that don't have a home is more than the pets that have a home
The statement is not misleading
B: 12.65 feet
if vanessa is already 7.25 feet down, and emily is 5.4 feet further, you would do 7.25+5.4 which is 12.65
The mixed number of it would be 5 42/45 if you're looking for the mixed number (to find the mixed number divide 267 and 45)
Answer: look at explanation
Step-by-step explanation:
1st question: 48 / 60 = 80 %

3rd : If 60% is 48 miles, than 10% is 8 miles. Therefore, 100% (his goal) = 80 miles.
4th: 1/4 of 88 = £22
