Answer:
1)· 5x + 2y = 9. First we solve for y. 2y= 9 -5x. y=(9-5x)/2. Now that we have the value of y. We substitute on the original equation and resolve. 5x + 2y = 95x + 2y = 9 5x + 2(9-5x)/2 = 9 5x + 9 - 5x = 9 9 = 9
That would be x = 1
Now substitute and resolve to find y.
5(1) + 2y = 9
5 + 2y = 9
2y = 4
y = 2
So our answer x=1 and y = 2. (1,2)
Proof :
5(1) + 2(2) = 9
5+ 4 = 9
9 = 9
Step-by-step explanation:
hoped it helped for the first one i didnt now the second one
first off let's convert the mixed fractions to improper fractions.
she already did half a hat, so we can say 
so she only needs enough fabric to make 3 more full hats, we know each one uses 9/7 ft, so
Answer:
3?
Step-by-step explanation:
i think that because it's multiplying by 3.
3*3= 9
5*3= 15
7*3= 21
9*3= 27
This is the only way i could think of helping in some sort of way! I'm sorry if it's wrong! (´。＿。｀)
Have a great day! (´。＿。｀) / (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧
