Answer : Z = 5
Step-by-step explanation :
62 = 9z + 17
-17 -17
45 = 9z
/9 /9
5 = z
Plug it back in :
62 = 9(5) + 17
62 = 45 + 17
62 = 62
Substitute x = 3 in any given equations. I will do in y = - x + 1
Therefore the answer is (3,-2)
Answer:
Step-by-step explanation:
-5.25+2.25 - 3
1-0.5 = 0.5
=-6 =m
y=-6x
Complentary angles add to 90 degrees
a and b are complentary
a+b=90
a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7
m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37
angle a measures 53 degrees
angle b measures 37 degrees
You find the greatest common factor of both numbers. For example 12/18 would be 2/3 because 6 goes into 12 and 18. After finding the GCF you just divide both numbers by it to get the simplified form
