Answer:
HI=1/2*EF
17-3x=1/2*-9x+37
2(17-3x)=-9x+37
34-6x=-9x+37
-6x+9x=37-34
3x=3
x=3/3
x=1
now substitute the value of HI
17-3x
=17-3*1
=17-3
=14
Step-by-step explanation:
Note :HI=1/2*EF because the straight line joining the mid points of two sides of a triangle is parallel to the third side and equal to half of it.
Answer: 34 degrees
Step-by-step explanation:
The starting temperature was -5 degrees at 5am, and after two hours, the temperature was 34 degrees at 7am. The temperature increased by 39 degrees, how did we get this answer?
You add -5 and 39
-5 + 39 = 34
A tip for adding negatives:
When you get a problem similar to -5 + 39, you can actually flip them around if you need an easier understanding. So it would be 39 - 5. Both equations still equal 34 as long as you keep the values of each number!
