Answer:
Hi there!
Your answers are:
a) x= 10
b) x= 4
c) x= 2
Step-by-step explanation:
a) 5+2x=25
-5
2x= 20
/2
x= 10
<u>Plug back in!</u>
5+2(10)= 25
5+20=25
25=25✓✓✓
b) 14= 5x-6
+6
5x= 20
/5
x= 4
14= 5(4)-6
14= 20-6
14=14✓✓✓
c) 15= 4x+7
-7
8= 4x
/4
2=x
15= 4(2)+7
15= 8+7
15= 15✓✓✓
Hope this helps!

Answer: 120 degrees</h3>
==============================================
Work Shown:
n = number of sides = 6
i = measure of interior angle
i = 180(n-2)/n
i = 180(6-2)/6
i = 180(4)/6
i = 720/6
i = 120
Each interior angle of this regular hexagon is 120 degrees.
-----------------
Alternative Approach:
E = exterior angle
E = 360/n
E = 360/6
E = 60
Each exterior angle of this regular hexagon is 60 degrees
i+E = 180
i = 180-E
i = 180-60
i = 120
We get the same answer.
Answer:
Her average speed was 48..88 mph
Step-by-step explanation:
Use a rule of 3 to find the time she traveled at 60 mph:
60 miles ----------1 hour
40 miles ---------- x
60x = 40
x = 40/60 = 0.67 hours
She traveled 40+50= 90 miles
During 1.25+0.67= 1.92 hours
90/1.92 = 48.88 mph
401,322 is less than 410,322.
