Answer:
Step-by-step explanation:
I don't know if this is what you are looking for but, I would use substitution to solve what x and y are
6x+2y = 1
is the same as -6x-2y= -1 because if you multiply everything by -1 it will equal
6x+2y = 1
so now you have
6x+2y = 1
6x+2y = 1
I would set the equation equal to one variable and substitute.
6x+2y = 1 = 2y = 1 - 6x = y = (1/2) - (6x/2) = y = (1/2) - 3x
now plug in (1/2) - 3x in to one of the y's because they are the same equation
6x + (1/2) - 3x = 1
subtract 1/2
6x - 3x = 1/2
subtract the x's
3x = 1/2
now divide both sides by 3
x = (1/2)/ 3
x = 1/6
now that you know what x equals, plug that into the equation and find y
6(1/6) + 2y = 1
1 + 2y = 1
subtract 1
2y = 0
now divide to find y
y = 0/2
y = 0
so
x = 1/6 and y = 0
Answers:
680 to 578
340 to 289
250 to 212.50
Reasoning:
To find the percent of a number:
If the percentage is less than 100, we place a decimal point in front of the percent. Then, we multiply the percent by the whole.
For example, .15 x 680 = 102. Since 15% is less than 100, we place a decimal point in front of the 15. Then, we just multiplied it by the whole of 680.
We know that 102 = 15% of 680, so since that is the amount of money taken off the total, we subtract it: 680-102=578. Therefore, the new price is 578.
I did this for the rest of the questions, and there are 3 correct answers:
680 to 578
340 to 289
250 to 212.50

Answer:
Which expression is equivalent to ((4^((5)/(4)).4^((1)/(4)))/(4^((1)/(2))))^((1)/(2))?
J = 7 × 6
j = 42
j is 7 times greater than 6, so you have to put j equal to 7 times the number 6 :)
