<span>"If the number is decreased by the number with its digits reversed, the result is 36"
u - 10t =36 -----> (2)
By subtracting the equation we can find t.

-(u-10t=36)</span>
______________
0u +20t = 26 -36
---> 20t = -10
t= -10/20
t= -1/2
Inserting value t in (1)
10t + u = 26
10(-1/2) + u= 26
-5+u=26
u= 26+5 = 31
<span>
Using u and t in the original expression 10t+u express a positive number
10t+u
= 10(-1/2) +u
= -5 + 31
= 26
----> Proves this statement is true

Answer:
(c) 4 left, CCW 90°
Step-by-step explanation:
Any of the image segments is perpendicular to the corresponding pre-image segment, so rotation is 90°. There is no reflection or rotation of 180° involved (eliminates choices A and D.
Points A and D that started in the 2nd quadrant are in the 3rd quadrant after the transformation. This tells you the rotation is CCW, not CW. (eliminates choice B) Even before you figure what translation is involved, the only reasonable choice is C: translation left 4 and rotation 90° CCW.
Let me see if I can decipher that :P
3/(3x)+1/x+4=10/(7x) first we need to make all terms have a common denominator of 21x...
(21+21+84x)/(21x)=30/(21x) multiplying both sides by 21x leaves you with
21+21+84x=30 combine like terms on left side
42+84x=30 subtract 42 from both sides
84x=-12 divide both sides by 84
x=-1/7
Answer:
1 gallon and 1 pint
Step-by-step explanation:
I guess that the actual amount of water needed per player is 1/8 of gallon and not 18 gallons.
You will need to bring 9 x 1/8 = 9/8 = 1 ¹/₈ gallons or 1 gallon and 1 pint
1 gallon = 4 quarts = 8 pints = 16 cups = 128 ounces
or
1 gallon = 3.785 liters
The US is one of the few countries (along with Liberia, and Myanmar) that still uses the imperial system to measure things, e.g. inches, feet, yards, pounds, miles, pints, gallons, etc. The rest of the world uses the metric system, e.g. meters, liters, kilograms, etc.
