Answer:
7
Step-by-step explanation:
x +4+2x+1+3x-2 = perimeter of triangle.
(6x +3)ft = perimeter
given perimeter = 45feet
hence,
6x + 3 = 45
6x = 42
x = 7
Hope it helped!! plz mark brainliest!! have a good day !! :)
Answer:
x = 11.5
Step-by-step explanation:
Taking the logarithm base 2 will transform this to a linear equation.
2(2x+7) = 3(2x -3)
0 = 3(2x -3) -2(2x +7) . . . . subtract the left side
0 = 2x -23 . . . . . . . . . . . . . simplify
0 = x - 23/2 . . . . . . . . . . . . divide by 2
11.5 = x . . . . . . . . . . . . . . . . add 11.5
The solution is x = 23/2 = 11.5.
_____
<em>Check</em>
This value of x makes the equation become ...
4^(2·23/2 +7) = 8^(2·23/2 -3)
4^30 = 8^20 . . . . . true
<span>find the range. [15(35)]+[12(60)] and this will be your high end. now do it again but at the low end [15(20)]+[12(30)] and this will be your low end. now you have the max amount the price would be and the lowest amount of the price. now look at your answers and see what is within that range and what isn't and there's your answer.</span>
Correlation is what you're looking for. Basically, it means that the two numbers are somehow related. Some examples of correlation would be positive correlation, negative correlation, and no correlation.

Answer:
x = 3
y = 8
Step-by-step explanation:
Since it gives you x, you need to plug in the number given for it into the equation:
y = 3x - 1
y = 3(3) - 1
y = 9 - 1
y = 8
So now you have, x = 3 and y = 8
