Answer:
x=3 y=4
Step-by-step explanation:
x+y=7; x + 2y =11
step: solve x + y = 7 for x:
x + y+ -y =7 + -y (add -y to both sides)
x = -y + 7
step: substitute -y + 7 for x in x + 2y =11:
x + 2y = 11
-y + 7 + 2y = 11
y + 7 =11(simplify both sides of the equation)
y + 7 + -7 = 11 + -7 (add -7 to both sides)
y = 4
step: substitute 4 for y in x = -y + 7:
x = -y +7
x = -4 + 7
x = 3 (simplify both sides of the equation)

Please rate brainliest
40 hours. Armando reads 20 pages per 4 hours. 20*10 would get to 200 which is the total amount of pages. So you would multiply the amount of hours by the same amount 4*10 which = 40 hours total.
Answer:
75 feet per hour
Step-by-step explanation:
Here, you are essentially given two points on a graph, only they are not graphed. You can visualize (2, 400) and (6, 700), and use the rate of change formula to find the average rate of change.
Then, simplify until you arrive at your solution.
feet per hour
Pretty sure it’s 4/x-1 if u use synthetic division.
