23/50 you want the denominator to be 100 so you multiply both by 2
then you get
46/100 or you can divide and get .46
to turn it to a percentage multiple by 100
.46 and 46%
Answer:
From not having solution the system changed to have solution
Step-by-step explanation:
step 1
we have
----> inequality A
----> inequality B
Solve the system of inequalities by graph
using a graphing tool
The system has no solution , because the dashed lines are parallel lines
see the attached figure N 1
step 2
we have
----> inequality A
----> inequality B
Solve the system of inequalities by graph
using a graphing tool
The solution is the shaded area between the two dashed lines
see the attached figure N 2
therefore
From not having solution the system changed to have solution
Answer:
c
Step-by-step explanation:
The dots cannot intersect
You missed an operand in the set of parentheses...if it was (x-9) we have:
5(x-9)-23=42 do multiplication indicated on left side...
5x-45-23=42 sum up like terms on left...
5x-68=42 add 68 to both sides
5x=110 divide both sides by 5
x=22 since this answer isn't in your choices the parentheses must have contained (x+9)...uggh :)
5(x+9)-23=42 perform indicated multiplication on left side...
5x+45-23=42 combine like terms on left side...
5x+22=42 subtract 22 from both sides
5x=20 divide both sides by 5
x=4
