So to solve this question the first step should be to make 7 equal to 42. To do this multiply 7 by 6, likewise with x-4.
The new equation should be 42/6x-24 = 42/12.
We now can just get rid of the numerators (top number) to get 6x-24=12.
The next step is to add 24 to both sides which would leave you with 6x=36.
Divide by 6 and the answer should be x=6

Step-by-step explanation:
Heart rate will be represented by 
, minutes will be represented by 
.
Here's the equation I came up with:
We can also rearrange it to look like a point-slope equation. Either way works, it's the same equation.
This works because her heart rate is decreasing by a constant value. The initial heart rate is like the y-intercept, while the amount that it decreases by is the slope.
I hope this helps!

Answer:
A = 110.25
Step-by-step explanation:
add all the equations and equal it to 180 because all triangle angles add to 180:
4x+1 + 3x + 3x-1 = 180
10x =70
/10 /10
x = 7
Insert x into each equation and solve:
3(7)-1 = 20
4(7)-1 = 27
3(7) = 21
and then use A = 1/2 base*height formula:
A= 1/2 21* 20
A= 210
