So you can plug in 15 and now the equation is x - 15 = 30. so then add 15 to 30 and so x is 45. you can plug in the numbers to see if it is correct. 45 - 15 does equal 30 so it is true. x = 45

Mazzeo's Appliance Store requires a down payment of on all install-

Tomtit [17]

Answer:

Norton's

Step-by-step explanation:

Suppose that the down payment of Mazzeo's store = 1/3 on all installment purchases

Whereas Norton's depot required 30% down payment on installment purchases.

1/3 is fractional value of 33.33%.

therefore, Norton's Store's down payment rate is lower than that of Mazzeo's store.

Answer:

X = 20.6 inches

Step-by-step explanation:

Pythagorean Theorem: $A^{2} =B^{2} +C^{2}$

A = 41.2 in, while B = 35.7 in and we are solving for C.

$41.2^{2} = 35.7^{2} +C^{2}$

$1697.44 = 1274.49 + C^{2}$

Now solve for C

$422.95 = C^{2}$

Take the square root

$20.5657482237 = C$
