Answer:
x=−y+19
Step-by-step explanation:
(x+5)(2)+(y−3)(2)=42
Step 1: Add -2y to both sides.
2x+2y+4+−2y=42+−2y
2x+4=−2y+42
Step 2: Add -4 to both sides.
2x+4+−4=−2y+42+−4
2x=−2y+38
Step 3: Divide both sides by 2.
2x
2
=
−2y+38
2
x=−y+19
Answer:
With a 5-digit number, you have 5 choices for the first digit. There will be 4 digits left so you have 4 choices for the second digit. After you have chosen the first 2 digits there will be 3 remaining so you will have 3 choices for the third digit. Hence there are 2 choices for the fourth digit and only 1 choice for the fifth digit. Thus you have made 5 × 4 × 3 × 2 1 = 120 choices and there are 120 possible 5 digit numbers made from 1, 2, 3, 2 and 1
6/16 I BELIVE but i am not too sure
There are many answers for a ratio question, and I do not know the choices but since each number could be divided by 30 I would. Do that to get 1:2:3. Hope this helps.
