What number can multiply to 8 but add up to 12

Answers

Answer 1

Answer: I don't think the numbers exist. 6 and 2 don't work because 6 * 2 does not equal 8. If you were solving a quadratic equation by factoring and you needed to find the two numbers, and you can't find them, you can solve the quadratic equation by using the quadratic formula.

Answer 2

Answer: Its 2 and 6
2*6=12
2+6=8

6.5-x
x/25

Answers

time = distance / speed

distance= x
speed = 25 mph

time = x/25

Ten plus eight times a number a equals eleven times another number d minus six solve for a

Answers

Answer:

$a=(11d-16)/(8)$

Step-by-step explanation:

We have been given a word phrase. We are asked to write an equation and solve for 'a'.

Eight times the number 'a' would be $8a$ .

Ten plus eight times a number 'a' would be $10+8a$ .

Eleven times another 'd' would be $11d$ .

Eleven times another 'd' minus six would be $11d-6$ .

Equate both expression:

$10+8a=11d-6$

$10-10+8a=11d-6-10$

$8a=11d-16$

$(8a)/(8)=(11d-16)/(8)$

$a=(11d-16)/(8)$

Therefore, the value of 'a' is $(11d-16)/(8)$ .

So your equation would be 8a+10=11d-6First: you would combine like terms so normally you would take away the smaller number. So to cancel out the negative 6 you added you add positive six to the negative 6 so you would get 0 and whatever you do to one side you have to do to the other so you would do 10 + 6. Your new equation would be 8a+16=11d. Now you do -16 to both sides. So your new equation would be 8a= 11d - 16. Now you divide by 8. So your final equation would be a=11d-2.
