Answer:
2.76
Step-by-step explanation:
you only round up if it is a five or higher
Answer:
y = 6x - 47
or
6x - y - 47 = 0
Step-by-step explanation:
Answer:
y=2x+6 ; x+y=51
Step-by-step explanation:
assuming x is one number and y is the other -
one number (y) is 6 more (+6) than twice another (2x) -
using that knowledge we form an equation -
y=2x+6
the sum (x+y) is 51
using this knowledge we can make the equation -
x+y=51
now you have -
y=2x+6 or 2x-y=-6
x+y=51
using system of equations -
you add the equations -
3x=45
x=15
y=51-x => y=36
hope this helps!!
Hey mate
here is your answer
length and width are given in the ratio are ;(4:7)
area of rectangle = (l×b)
therefore,
4x×7x=700
28x^2=700
x^2=700/28
x^2=25
x=5
length =4x=4×5=20, lenght =20 and width =7x so, 7×5=35 width.....
Answer:
13.9
Step-by-step explanation:
To get the length, or the hypotenuse, you do the equation a^2 + b^2 = c^2
Meaning you multiply those known lengths by themselves, then add them.
169 + 25 = 194
Then you find the square root of 194.
The square root would be 13.9283882772, or when rounded to the nearest tenth, 13.9
