Answer:

C, none of them are equivalent

BECAUSE

For A, the -4q should be positive 4q to apply

For B, the 2q when distributing with the parentheses should be negative 2q to work with the expression above

Hope this helps!

Answer:

None of these

Step-by-step explanation:

-6 +4q +(-6q)?

Combine like terms

-6 -2q

Factor out -2

-2(q+3)

The first answer given has -6q-4q = -10q

Put a digit in the gap, such that the answer is a whole number:
Makovka662 [10]

Answer: The possible digits are 2,5 and 8

Step-by-step explanation:

3x +486 = 100_

From the equation in the question, we are looking for a digit to put in the gap after 100 to make sure that when we solve the question, x will be a whole number.

Therefore, since it's a single digit required, the possible digits will be from 0 to 9.

Now, from divisibilty tests, for a number from 2 digits upwards to be divisible by 3, the sum of its digits has to be divisible by 3.

Going back to the question, let's divide each term by 3 to get ;

3x/3 + 486/3 = 100_ to give ;

x + 162 = 100_ /3

Now for x to be a whole number, the value on the right hand side must be a whole number.

Therefore, since we know that for a 2 digits and above number to be divisible by 3,it's sum must be divisible by 3. We can plug in any of the digits from 0-9 into the gap and add up.

For 0; 1+0+0+0= 1

For 1; 1+0+0+1 = 2

For 2; 1+0+0+2= 3

Following the same addition pattern for digits 3,4,5,6,7,8and 9, we'll get sum of 4,5,6,7,8,9 and 10 respectively.

Inspecting the above, the only additions that are divisible by 3 are when the digit is; 2,5 and 8

Find two numbers with the sum of 65.twice the smaller number is ten more than the bigger one
melomori [17]

Step-by-step explanation:

To begin, let’s represent both numbers with letters; x for the smaller number and y for the larger one

The question states that both numbers sum up to 65. With that, we can create our first equation:

x+y = 65

You also went on to say that the smaller number multiplied by 2, is equal to the sum of the larger number and 10. Therefore

2x = y+10

We can rearrange the first equation, place it in the second equation and find our answer. So,

Rearranging equation 1, we have y=65-x. Hence:

2x = 65-x +10

3x = 75

x= 75/3 = 25

Substituting this value into equation 1, we have ‘y’ to be 40 {65–25}

Proof: 2*25 = 50 = 40+10
