2×+7=27
2×-7=27-7
2× =20
2/× =20/2
× = 10
2(10)+7=27
3×+1=28
3×-1=28-1=27
3× =27
3/× =27/3
× =9
3(9)+1=28
27 does not equal 28
so no
42 degrees. Since the Ray is the angle bisector, that means it divides angle DEF into two angles with equal measure. So, divide 84 by 2 to get 42.
Answer:
4... hope this will help
Step-by-step explanation:
What this question is asking us is
A) From -40C to 5 0c How much did it rise
The formula for this would be
Risen Temperature - Initial Temperature
The risen temparauture is 5 so we plug the 5 in first then the 4 so it would look like
5-(-4)=9
And remeber when you have 2 negatives it becomes a positie, 5+4=9
The asnwer for A is 9 degress
B) The tempurater then fell by 7 degress from 5 so we just have to do
5 - 7
which is -2 Celcius
