Answer:
1
Step-by-step explanation:
since the 2 functions equal each other:
-2x + 3 = 4x - 9
add -2x to both sides
3 = 6x - 9
add 9 to both sides
12 = 6x
divide by 6
2 = x
you have x, now find y, you just need to plug 2 into one of the equations instead of both bc they both equal the same anyway
-2(2) + 3
-4 + 3
-1 = y
Now we'll find x + y, input them and it's 2 + (-1), which is 1
Answer:
26 1/2 is not equivalent to and integer but it can be approximated to 27 which is an integer.
Explanation
An integer is a whole number. It is a number that is not a fraction.
253/2=25+3/2=25+1 1/2=26 1/2
26 1/2 is not equivalent to and integer but it can be approximated to 27 which is an integer.

Answer:

Step-by-step explanation:
Given that Jack did 3/5 of all problems on his weekend homework before Sunday. On Sunday he solved 1/3 of what was left and the last 4 problems. We have to find the number of problems assigned for weekend.
Let the total problems be x


∴ Problems assigned for weekend are

⇒ 
calculation with distribuation would be multipling each fraction by 6 first then add them together
1/2 becomes 3 2/3 becomes 4 3/4 becomes 9/2 now add them together 23/2 or 11 1/2 Now without distribuation you woud add everything togther then mutiply by 6 adding together would give you 23/12 then multiplying by 6 gives you 23/2
