Your equation is a little messed up comment me the equation you need help with
-4(5g+8s=22.87)
5(4g+7s=18.89)
-20g-32s=-91.48
20g+35s=94.45
3s=2.97
s=.99
7(.99)+4g=18.89
6.93+4g=18.99
4g=13.6
g=3.4
Answer:
x=6
Step-by-step explanation:
its an equilateral triangle so all sides are the same measure
9=3x-9
18=3x
x=6
The inequality would be 3x(4)-5≤67; the solution is x≤6; the graph is attached.
To solve this, first multiply the coefficients of x:
12x-5≤67
Add 5 to both sides:
12x-5+5≤67+5
12x≤72
Divide both sides by 12:
12x/12 ≤ 72/12
x ≤ 6
Plot the points ( -4,2.5), (-3,3), (-2,1.5), (-1,2), (0,1), (1,2), (2,3.5), (3,0.5), (4,2.5) then connect them with a line
