The price of a pair of shoes after a 25% discount was $18.50. what was the original cost?

1 answer:

7 0

After a 25% discount...means that u paid 75%

so 75% of the original cost is 18.50...
0.75x = 18.50.....with x being the original cost
x = 18.50 / 0.75
x = 24.666 rounds to 24.67 <==

Answer:

Step-by-step explanation:

the shared hypotenuse and congruent legs of the triangle means it is congruent by HL

you might think that SSA is also doable because there is a right angle in both triangles but it is not

a way to remember this is that "there are no donkeys in geometry" because SSA backwards is another word for donkey

Change the decimal to fraction form or mixed number form and reduce if possible 73.437

harina [27]

Answer:

73.437= 74 437/1000

Step-by-step explanation:

73.437 to fraction.

Let's acknowledge the presence of a decimal and how many digit we have after the decimal point.

Actually, the numbers after the decimal point will determine the amount of 10s to be divided with.

What I'm saying is this

73.437= 74 437/1000

In this case, 437 is a prime number

73.437= 74 437/1000

If 4^x+1 = 64, then what is the value of x^4

Olin [163]

$4^{x} + 1 = 64 \\4^{x} = 63 \\ln(4^{x}) = ln(63) \\xln(4) = ln(63) \\x = \frac{ln(63)}{ln(4)}$

$(\frac{ln(63)}{ln(4)})^{4} = 79.78006702$

The value of x⁴ is equal to 79.8006702

What is the answer to this question?

Degger [83]

Answer:

$y = -\frac{19}{9}x + \frac{5}{3}$

Step-by-step explanation:

Given:

19x + 9y = 15

Required:

Rewrite in slope-intercept form, y = mx + b

SOLUTION:

19x + 9y = 15

Subtract 19x from both sides

9y = -19x + 15

Divide both sides by 9

y = -19x/9 + 15/9

$y = -\frac{19}{9}x + \frac{5}{3}$
