The answer to (1+_÷7+4)÷8= 4/7 is -3 I believe
Remember you can do anything to an equation as long as you do it to both sides
4x-5=4x+10
minus 4x both sides
-5=10
false
no solution
Looking at the given points on the right side from (0,2) to (1,6) for 1 increase in X ( 1-0=1) the Y value increases by 3 ( 6/2 = 3)
This same increase happens for th other two points: 18/6 = 3
54 / 18 = 3
The rate of increase is 3.
Setup Average Equation:
_____________________
Average=Sum of our 4 numbers + unknown number of x
____________________________________
Total Numbers
15 = 3 + 19 + 8 + 32 + x
______________
5
Cross Multiply
___________
3 + 19 + 8 + 32 + = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:
___________________________________________
x + 62 - 62 = 75 - 62
x = 13
