Answer:
The answer is infinitely many.
Step-by-step explanation:
5x + 3(x − 1) = 10x − 2x − 3 is simplified to 0=0, which is infinitely many solutions.
Answer:
The answer is 9/10.
Step-by-step explanation:
Step 1: 3/4/5/6. This means, 3/4 is being divided by 5/6 and so you write it in that form. Take this for an example. 2/4 divided by 3 is 2/4/3.
Step 2: 3/4 ÷ 5/6. This is because, we want the question to be easy to simplify. Also, we want to write the division question as a multiplication problem. And this sign ( / ) means to divide.
Step 3: 3/4 × 6/5. This is because in Maths, when a fraction is dividing another fraction, that fraction is reciprocated ( the fraction at the right side.) Reciprocated here means the denominator is made the numerator and the numerator is made the denominator.
Step 4: 3/2 × 3/5. How? We cancelled out. 2 goes into 4 twice and into 6 thrice.
Step 5: 9/10. We multiplied 3/2 × 3/5 to get 9/10.

Answer:
7 melons
Step-by-step explanation:
So we first figure out the unit price of each melon by dividing 7.5 with 3 and you get $2.5 per melon. Then you divide 17.5 by 2.5 and then you should get 7.
Answer:
CD is to DE as CB is to BA
4 is to 6 as 3 is to y
1.5 is to 3 as 3 is to 4.5
AC = AB + BC
AC = AB + 3
Since AB = 4.5 then AC = 7.5
The answer is C
