Answer:
Let x represents the week and y represents the amount of money.
As per the given statement:
Diego has $11 and begins $5 each week toward buying a new phone.
⇒ ......[1]
It is also given that Lin $60 and begins spending $2 per week.
⇒ ....[2]
when they have the same amount.
equate [1] and [2] we get;
Add both sides 2x we get;
Subtract 11 from both sides we get;
Divide both sides by 7 we get;
x = 7
Substitute the value of x = 7 in [1] we have;
Therefore, at x= 7 week they have the same amount of money and they have the amount at that time, $ 46

Answer:
2x(x − 3)(x + 3)
x(x + 4)(x + 2)
Step-by-step explanation:
2x³ − 18x
x(2x² − 18)
2x(x² − 9)
2x(x − 3)(x + 3)
x³ + 6x² + 8x
x(x² + 6x + 8)
x(x + 4)(x + 2)
Answer:
7y + 5z + 10
Step-by-step explanation:
2y + 7z - 2z + 4y + 8 + y + 2
Like terms are terms that have the same variable part.
2y, 4y, y are like terms (remember that y is the same as 1y when you add)
7z, -2z are like terms
8, 2 are like terms
2y + 7z - 2z + 4y + 8 + y + 2 =
= 2y + 4y + y + 7z - 2z + 8 + 2
= 7y + 5z + 10
47/8 is an improper fraction so we need to divide 47 by 8 to get an mixed number.
8 go into 47, 5 times because 5*8 equals 40.
47-40 is 7 that is the left over.
5 7/8 is your mixed number.
