<span>the question is 3 variable equation solution
the three equation will be
5x+4y+7z=152
3x+2y+5z=92
2x+2y+4z=74
solving by elimination we get
x=11,y=12,z=7</span>
Answer:
No. Rob was correct to extend the lines to the origin, but the points should be on a single straight line. He made two straight lines.

Answer:
m∠FJH=60°
Step-by-step explanation:
The complete question is
JG bisects FJH, FJG= (2x + 4)° and GJH = (3x -9)°
What is FJH
we know that
m∠FJH=m∠FJG+m∠GJH -----> equation A
If ray JG is an angle bisector of ∠FJH
then
m∠FJG=m∠GJH -----> equation B
substitute the given values in equation B and solve for x
(2x + 4)°=(3x -9)°
3x-2x=4+9
x=13
Find the measure of angle FJH
m∠FJH=(2x + 4)°+(3x -9)°
substitute the value of x
m∠FJH=(2(13) + 4)°+(3(13) -9)°
m∠FJH=(30)°+(30)°
m∠FJH=60°
Answer
Multiply the divisor and dividend by
✔ 100
The new division problem becomes
✔ 4,860 ÷ 15
The quotient of 48.6 ÷ 0.15 is
✔ 324
Estimating to check, you get
✔ 5,000 ÷ 15 = 333.33
