Answer:
length of the longest side is less than 21
Step-by-step explanation:
5n+6n+7n=18n
18n<54
n<54/18
n<3
7*3=21( longest side.
)
Step-by-step explanation:
Let the number be x,
Now,
The difference of a number and 3 is equal to the quotient of 10 and 5.
- (x-3)=(10/5)
- x-3=2
- x=2+3
- x=5
Her total bill is $186 because :
(3x39)+15+(2x27)
Answer: Volume of cylinder is (3.14) x (radius squared) times height, or nr^2h
Step-by-step explanation:
Answer:
There are 42 red colour socks and 44 green color socks
Step-by-step explanation:
Let there are r red socks and g green socks.
ATQ,
He has three times times as many red socks subtracted from four times as many green socks which he believes is 50 socks.
4g-3r=50 ....(1)
Half the number of green socks plus one-third of the number of red socks is 36.
Multiply equation (1) by 2 and equation (2) by 3.
8g-6r = 100 ....(3)
9g +6r = 648 ....(4)
Add equation (3) and (4)
8g-6r + 9g +6r = 100+648
17g = 748
g = 44
Put the value of g in equation (1).
4(44)-3r=50
176-3r = 50
176-50 = 3r
r = 42
Hence, there are 42 red colour socks and 44 green color socks.
