Absolutely not. The least mixed numbers are 1 and 1/2, and 1 1/2 + 1 1/2 is 3, so no, it is not possible. Hope I helped!
Answer:
<h2>n>8</h2>
Step-by-step explanation:
Step one:
given data
needed amount= $80
the amount already saved= $8
earnings per hour= $9
let the number of hours worked be n
and let y represent the total
the situation represented linearly is
y=mn+c
Step two:
substituting our data to find n
9n+8>80
9n>80-8
9n>72
divide both sides by 9
n>72/9
n>8
Therefore he must work a minimum of 8houees
Answer:
4y - yx(3-7y) + 5 + 2(8-y) equals to 7xy^2 − 3xy + 2y + 21
Step-by-step explanation:
1. Multiply numbers inside the parentheses.
4y - yx(3-7y) + 5 + 2(8-y)= 4y − 3yx + 7y^2x + 5 + 16 − 2y
2. Then combine all like terms
4y − 3yx + 7y^2x + 5 + 16 − 2y
4y - 2y = 2y
2y − 3yx + 7y^2x + 5 + 16
5 + 16 = 21
2y − 3yx + 7y^2x + 21
3. After combining like terms, simplify.
2y − 3yx + 7y^2x + 21
Move y^2
2y − 3yx + 7xy^2 + 21
Move 2y
− 3yx + 7xy^2 + 2y + 21
Reorder - 3yx and 7xy^2 (7xy^2 is more bigger than -3yx)
7xy^2 − 3yx + 2y + 21
4. Final answer = 7xy^2 − 3xy + 2y + 21
