4x²+22x+28 , you can solve this using FOIL (first, outter, inner, last)
Answer:
x=1, y= 7
Step-by-step explanation:
−5x+2y=9
y=7x
Substitute the second equation in for the first
-5x +2(7x) = 9
-5x + 14x = 9
Combine like terms
9x = 9
Divide by 9
9x/9 = 9/9
x =1
Now find y
y = 7(1)
y =7
Question:
Madison and Allie have a goal to read 3,300 pages together by the end of 3rd quarter. Madison reads 50 page every day Allie reads 10 more pages every day than Madison reads. Write and solve an equation to show how many days it will take them to read 3,300 pages
Answer:
It will take 30 days for them to read 3,300 pages
Step-by-step explanation:
Given:
The total number of pages to be read = 3300 pages
Number of pages Madison reads = 50 page every day
Number of pages Allie reads = 1 0 more pages every day than Madison reads
To Find:
Total Number of days needed to read 3300 pages = ?
Solution:
Let the number days they will take be x
then
Number of pages Madison read per day (x) + Number of pages Allie read per day(x) = 3300
(50)x + (50 +10) x = 3300
50x + 60x = 3300
110x = 5500
x =
x = 30
