That's a lot of questions. First, they're asking for how much each person pledged. Ivan said he would give $4.25, plus $1.25 per mile. As an expression, that would be 1.25m+4.25 . Vicky said that she would give $5.75, plus $.75 per mile, which would be .75m+5.75 . The second problem asks you to add the two, so add 1.25m and .75m to get the total amount she would earn per mile, which is $2. If I got paid $2 for every mile I biked, I would bike a marathon. Then add the flat payments of $4.25 and $5.75, and you get $10. So, the final equation would be 2m+10.
The last question is asking for you to find an equivalent proportional expression. To find this, you can just dividing by the greatest common factor of the two numbers. I got 2, so the equation would be 1m+5.
Answer:
113 degrees
Step-by-step explanation:
Two angles are called supplementary when they add up to 180 degrees

Yes I’m Pretty sure it is 56 cups
Hope this helps!!
Add 3y to both sides
10x = -150 +3y
subtract -150 from both both sides
10x + 150 = 3y
then divide both sides by 3 (and going to switch the two sides cuz i prefer it that way)
y = (10/3)x + 50
so for graphing you take the y intercept
which is 50 and put a point there
slope (10/3) is rise/over run
so going down and to the left from your y intercept (cuz the slope is positive) count 10 then go over 3
put a point
do it again
then for the other way go up 10 and over 3
that’s graphing
i’ll graph it too but it’ll be sloppy so i figured i’d explain it too
13,000
if it is lower than 500 you round down,if it is higher than 500 you round up
