Answer:
120
Step-by-step explanation:
i don't know if you still need help, but the answer is x=180-30-30=120 degrees
(4x + 2) more minutes is spent running on the treadmill than lifting weights
<em><u>Solution:</u></em>
Given that,
your friend spends 6+5x minutes lifting weights
9x+8 minutes running on a treadmill
Therefore,
Time spent on lifting weight = 6 + 5x minutes
Time spent on treadmill = 9x + 8 minutes
<em><u>Write a polynomial that represents how much more time is spent running on the treadmill than lifting weights</u></em>.
Thus we need to find the difference between time spent on treadmill and time spent on lifting weight
Difference = Time spent on treadmill - Time spent on lifting weight
Difference = 9x + 8 - (6 + 5x)
Difference = 9x + 8 - 6 - 5x = 4x + 2
Thus 4x + 2 more minutes is spent running on the treadmill than lifting weights
Step-by-step explanation:
In a equation of a line
y=mx+c
Let's take two points from the graph (0,1) and (4,3)
Slope=m= (3-1/4-0)= 2/4=1/2
C= 1
y=½x+1
Answer:
x = -3
Step-by-step explanation:
3x + 9 = 12x + 36 (rewrite)
3x - 12x + 9 = 36 ------> 3x - 12x = 36 - 9
3x - 12x = 36 - 9 (collect like terms)
-9x = 36 - 9 ( substract)
-9x = 27 (divide both sides for the answer)
-9 -9
x = -3
