Assign two variables for each problem, and write the equations. Do not solve.
NemiM [27]
Price of boots is represented as x, price of tennis shoes is represented as y. x-y=44.38 x+y=196.12 Isolate x. (Or y, if you wanted to) x=y+44.38 x=196.12-y Set them equal to each other. y+44.38=196.12-y Solve for y. Then plug it in to either of the two original equations to find x. x=120.24 y=75.86 Note: This is assuming that the boots are more expensive than the tennis shoes. If the tennis shoes are more expensive than the boots, then the prices would be switched. I didn't find this clear in your question.

eXCUSE ME!!! I NEED HELP PRONTO!! BRAINLIEST PLS! in a fraction the denominator is 4 less than the numerator. If 3 is added to b
avanturin [10]

7/5 = 14/10 = 28/20

Numerator = x

Denominator = x-4

Add 3 to both:

x +3 / (x-4+3)

x+3 = 14

(x-4 +3) = 10 = x-1 = 10

x = 11

Check:

11 -4 = 7 ( denominator is 4 less than the numerator.)

add 3 to both:

11+3 = 14

7+3 = 10

14/10 reduces to 7/5

The original fraction would be 11/7

What is the missing base 256 = ^4
Inessa05 [86]
So the problem is 256=x^4 and you need to find x.

You can find x by taking fourth root of 256. The easiest way is to use your calculator. On my scientific calculator, it is 2nd then the button ^ that is \sqrt[x]{}
You get the answer of 4.
