Answer:
73
Step-by-step explanation:
647 - 574
1.) subtract 7 -4 and you get 3 in the ones place.
2.) next you have to do 4 -7 and you can't do that so you take one from the hundreds place and turn the 6 into a 5.
3. make the 4 a 14 and then subtract 14-7 and you get 7 in the tens place
4.) you are then left with 5-5 in the hundreds place which is 0 so your answer is 73
The answer would be 6x(5x-2).
Since both terms have x in them, x will be apart of your answer.
The GCF of 12 and 30 is 6.
So you can factor out 6x from both terms.
Hope this helps!
Answer:
5 quarters and 2 dimes
Step-by-step explanation:
5 quarters make 1.25 + 10 cents = 1.45
X is Kevin; Y is Dan
X = 3Y
X - 4 = 5(Y - 4)
3Y - 4 = 5(Y - 4)
3Y - 4 = 5Y - 20
+ 4 +4
4 cancels each other out.
3Y = 5Y - 16
- 5 -5
5 cancels each other out.
-2Y = -16
/2 /2
Y = 8
X = 3Y;
X = 3 x 8;
Thus,
X = 24;
Kevin(x) is 24
