Ok so the ratio from Joe to Sam is 3:11
Joe = 3x while Sam = 11x
So if Joe = 3x = 33 then 3x = 33 and we use the Division POE (Property of Equality) and divide in both sides by 3. 3x/3 = 33/3, x = 11
Now that we know x = 11 we can use it for Sam, 11 x 11 = 121, Sam has 121 and Joe 33
The Question is how much they have in total so we add them, 121 + 33 = 154, *154 is the answer* ;)
The answer is as follows...i tried to post this on the other question you asked but it didnt attach so i apologise
Expression 1; If your friend bikes 1.5 miles home from school each day for 4 weeks, they bike a total of - miles in that time period. The math I did was multiply 5 by 4 to get 20 school days in 4 weeks, and multiplied 1.5 by 20 to get 30 miles biked in 4 weeks.
Expression 2; If you bike 3.25 miles home from school each day, using the same math shown in the previous expression, substituting 1.5 for 3.25. Using that math, you would bike 65 miles in 4 weeks.
Sarcastic conclusion; You and your friend both get quite the leg day just to get home from school!
Answer:
A solution point is (2,2)
Step-by-step explanation:
Graph the lines. If it is just greater that or less than, use dashed lines. I fits greater than or equal too, or other symbols like that, use a solid line
Use the test point (0,0). If it satisfies the inequality, shade the side of the graph with that point (you can use any test point, not just (0,0)). If it doesn't satisfy, then shade the other side
The Shaded area shared by both lines is the area of the solution
Step-by-step explanation:
2(x+10)=60
x+10=60/2
x=30-10=20
