Answer:

x=6

XY=24 units

YZ=18 units

Step-by-step explanation:

we have that

Y is between X and Z

$XZ=XY+YZ$

substitute the given values and solve for x

$42=4x+3x\\42=7x\\x=6$

therefore

$XY=4x=4(6)=24\ units\\YZ=3x=3(6)=18\ units$

Justin has $57.18 in his checking account. He deposits his paycheck of $256.79. He then buys $68.42 in groceries, $50.00 in gas,

aalyn [17]

$57.18 + 256.79 = 313.97

313.97 - 68.42 = 245.55

245.55 - 50.00 = 195.55

195.55 - 31.06 = 164.49
