a. 60(h)+40=
b 60(3)+40=
180+40=$220
c. 400=60(h)+40=
360=60(h) *divide 60 on each side*
6=h, 6 hours
Answer:
<h2><u><em>
x = 9</em></u></h2>
Step-by-step explanation:
2x-10=8
2x = 10 + 8
2x = 18
x = 18 : 2 =
x = 9
-----------------------
check
2 * 9 - 10 = 8 (remember PEMDAS)
18 - 10 = 8
8 = 8
the answer is good
36/32 = 1.125
36 is 1.125 times the size of 32, or 0.125 time greater than 32.
Y=-7
When a slope is zero the line will be vertical so basically all you need to do is get the Y of your points and use that in your sub intercept equation
15. 6 - -3 = 6 + 3 = 9. Answer: 9 degrees C
16. 7 - -7 = 7 + 7 = 14. Answer: 14 degrees F
17. -1 - -5 = -1 + 5 = 4. Answer: 4 degrees C
18. 5 - -2 = 5 + 2 = 7. Answer: 7 degrees C
19. 130 - -110 = 130 + 110 = 240. Answer: 240 degrees C
