Step-by-step explanation:
Answer:
first I would combine terms which would give me
-4x-7=-7-4x
then I would get the variable on each side of the equal sign
0=0
lastly I would verify the solution
infinite solutions
Step-by-step explanation:
combining combining like terms would give you negative 4x - 7 which is equal to -7 - 4x. if you were to add 7 on either side and 4 on either side you would get 0 = 0 because this is correct it's infinite solutions
Answer:
I would say that they are different because if x - a has a value to the equation then that means a - x will not have the same value because it may be rearranged to a different equation but that doesn't mean that they will have the same value. that explain why x - a and a - x are not the same
An item that costs $30, when discounted 15 percent, will cost $25.5. The easiest way of calculating discount is, in this case, to multiply the normal price $30 by 15 then divide it by one hundred. So, the discount is equal to $4.5. To calculate the sales price, simply deduct the discount of $4.5 from the original price $30 then get $25.5 as the sales price.
1) Dimensions of rectangle are 14 and 7. Perimeter is:
2*(14+7) = 42.
2)Let the number of students who chose Tiger be x.
Number of students who chose Bulldog is 4*x.
Number of students who chose Lion is 2*x.
7x = 273 -> x=273/7=39.
Answer is 2*x=78.
3) The answer is B).
A and C aren't answers because they start with positive and end with negative numbers and D isn't answer because -6 1/4 is greater than -6,53.
