Answer:
462 words
Step-by-step explanation:
Maxine types :
294 words ⇒ 7 minutes
Let the known number of words be x.
So,
294 words ⇒ 7 minutes
x words ⇒ 11 minutes
Therefore,
294 ⇒ 7
x ⇒ 11
Now use cross multiplication and find the value of x.
7x = 294 × 11
7x = 3234
Now divide both sides by 7.
x = 462 words.

Answer:
x = 
or 0.706
or 1.735
Step-by-step explanation:
5x + 2y=7 ----->(eq 1)
- 2x + 6y=9 ----->(eq 2)
Multiply (eq 1) with 3
3×(5x + 2y) = 3×7
15x + 6y = 21 ----->(eq 3)
substract (eq 3) from (eq 2)
- 2x + 6y - (15x + 6y) = 9-21
- 2x + 6y - 15x - 6y = 9-21
- 2x - 15x + 6y - 6y = 9-21
-17x = -12
x = -12 ÷ -17
x =
put x = in (eq 1)
