Answer:
Answer:
28+66+86=180
180=180
Step-by-step explanation:
Since there is a triangle and the 3 measures from the angles we can find the value of x using the hint given that the sum of the interior angles must be 180°
Write the equation
\begin{gathered}x+(2x+10)+(3x+2)=180\\\end{gathered}
x+(2x+10)+(3x+2)=180
Simplify left side of the equation
\begin{gathered}6x+12=180\\\end{gathered}
6x+12=180
Solve equation for x
\begin{gathered}6x=180-12\\6x=168\\x=28\end{gathered}
6x=180−12
6x=168
x=28
Replace x into the 3 angles and find their respectives values
\begin{gathered}A=x\\A=28\\\\B=2x+10\\B=2*28+10\\B=56+10\\B=66\\\\C=3x+2\\C=84+2\\C=86\end{gathered}
A=x
A=28
B=2x+10
B=2∗28+10
B=56+10
B=66
C=3x+2
C=84+2
C=86
Check if the answers are correct
\begin{gathered}28+66+86=180\\180=180\end{gathered}
28+66+86=180
180=180

Answer:
x>10
Step-by-step explanation:
4(2x + 2) + 12 > 100
Subtract 12 from each side
4(2x + 2) + 12 -12> 100-12
4(2x + 2) > 88
Divide by 4
4/4(2x + 2) > 88/4
2x+2 > 22
Subtract 2
2x+2-2 > 22-2
2x> 20
Divide by 2
2x/2 >20/2
x>10
In linear functions (mx+b), the m is the slope, therefore the -2 is the slope.
Paper route earnings each week=($87.8-$37.8) / 10 =$5
If $5=20% we have to find how money is the 100%.
$5-----------------20%
x------------------100%
x=($5*100%) / 20%=$25
solution: $25.00
