Answer:
86
Step-by-step explanation:
a straight angle is 180
40+54+x=180
94+x=180
x=180-94
x=86!
Answer:
m= 15
Step-by-step explanation:
first you subtract 2/3 from both sides (m/9)+(2/3)-(2/3)= (7/3)- (2/3)
now you will have (m/9)= (5/3)
to get (m) on its own you have to multiply the both sides by 9
(m/9) times 9= (5/3) times 9
m= 45/3 or 15
Answer check:
substitute (m) for 15
(15/9)+(2/3)= (7/3)
first you should simply (15/9), so all of them will have a common denominator
(5/3)+(2/3)=(7/3)
(7/3)=(7/3)
Factor both the top and bottom.
(2(x-6)(x-2))/((x+6)(x-4))
To find zeros, the numerator must be 0. The denominator cannot be 0 because anything divided by 0 is infinity.
(x-6)=0
x=6
(x-2)=0
x=2
Final answer: x=2, x=6
Answer:
The integers are 7 and 14.
Step-by-step explanation:
y = 2x
1/y + 1/x = 3/14
1/(2x) + 1/x 3/14
1/(2x) + 2/(2x) = 3/14
3/(2x) = 3/14
1/2x = 1/14
2x = 14
x = 7
y = 2x = 2(7) = 14
Answer: The integers are 7 and 14.
