Answer: Y = 9

Step-by-step explanation:

Y & X

Y = KX

K = Y / X = - 15 / - 5 = 3

X = 3

K= 3

Y=?

Y = KX = 3 x 3 = 9

Therefore, when X = 3, Y = 9

solmaris [256]
If 6 is placed at the right end of AB, so the number is AB6. 
the value of the three-digit number formed is 294 more than AB, means that if AB6 - 294 = AB <span>

</span>AB 6 
- 2 9 4 
AB <span>

</span>6 - 4 = B = 2 <span>

</span>If B = 2, then the tens digit is 2 - 9 (which can't be) so 12 - 9 = 3 = A <span>

Maxine types 294 words in 7 minutes. How many words does Maxine type in 11 minutes?<br> 352 words
WINSTONCH [101]

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.

Hope this helps you :-)
