Answer:
You use the Pytha. theorem to find the length of the missing side or the hypotenuse
Step-by-step explanation:
a^2 + b^2 = c^2
c^2 = the hypotenuse
Answer:
$21.40
Step-by-step explanation:
List price = $19.95
Sales Tax Rate = 7.25%
Total sales tax = 19.95 x 7.25/100 = $ 1.45
Total cost = 19.95 + 1.45 = $21.40
Answer:
The ratio is 4:12:15.
Step-by-step explanation:
we need to make the first ratio (Sylvia's to John's) comparable to second one (John's to Peter's). Since John is in both ratios, we use his number to make it the same. 3 and 4 can both be multiplied into 12. So, multiply the first ratio by 4 and the second by 3.
![(1:3) * 4 = 4:12\\(4:5) * 3 = 12:15](https://tex.z-dn.net/?f=%281%3A3%29%20%2A%204%20%3D%204%3A12%5C%5C%284%3A5%29%20%2A%203%20%3D%2012%3A15)
Put it together, and you get 4:12:15.
Hope it helps :P
Answer:
the value of x in x? (-8x = 24) - 6x +18 - 122 is x=40
Hope you do good :)
Answer:
x = -8
Step-by-step explanation:
4( 3x +5 ) - 3 = 9x -7
Distribute
12x +20 -3 = 9x -7
Combine like terms
12x+17 = 9x-7
Subtract 9x from each side
12x-9x +17 = 9x-9x-7
3x +17 = -7
Subtract 17 from each side
3x+17-17 = -7-17
3x = -24
Divide each side by 3
3x/3 = -24/3
x = -8
