Answer:
4
Step-by-step explanation:
Given that three pairs of gloves- a red pair, a blue pair, and a green pair-are in a drawer. The gloves are removed at random without returning any to the drawer.
We have to find the minimum number that must be removed in order to guarantee having a matched pair of gloves
No of different colours = 3 (red, blue, green)
Hence no of gloves that must be removed = 3+1
If 4 gloves are removed, only 3 can be of different colours 1 will have same colour as any one of the three.
So a pair of same colour would be obtained
Answer is 4
X + (2 10)/(30 x)
The gcd of 10 and 30 is 10, so 10/30 = (10×1)/(10×3) = 10/10×1/3 = 1/3:
x + 2/(3 x)
Put each term in x + 2/(x 3) over the common denominator 3 x: x + 2/(x 3) = (3 x^2)/(3 x) + 2/(3 x):
(3 x^2)/(3 x) + 2/(3 x)
(3 x^2)/(3 x) + 2/(3 x) = (3 x^2 + 2)/(3 x):
Answer: (3 x^2 + 2)/(3 x)
or,b²=576-81
or,b²=495
.
step by step explaination
b²=h²- p²
or,b²=24²-9²
or,b²=576-81
or,b²=495
or, b²=root under 5×3×3×11
:. b²=3 root under 55
Correct Question:
Stan ran 
miles, which was 
fewer miles than Matt ran. Four students wrote and solved equations to find m, the number of miles that Matt ran. Which student wrote and solved the equation correctly?
Molly’s work:
Emma’s work:
Alysa’s work:
3 and two-fifths
Maddie’s work:
Answer:
Molly's Work is correct
Step-by-step explanation:
Let S represent distance covered by Stan and M represent the distance covered by Matt;
Given that the distance covered by Stan is miles and it is miles less than that covered by Matt;
This can be represented mathematically as
By substituting for S;
This gives
By collecting like terms
becomes
Reorder
---- This is the correct equation
Solving further to get the distance covered by Matt;
Split fraction
Collect like terms
Add fraction (Take LCM)
Divide Fraction
Hence, the equation of the system is
and the solution is
Molly’s work is correct
