Plug in each possible value into the equation.
when m = 5
2k = m + 3
2k = (5) + 3
Simplify
2k = 8
isolate the k, divide 2 from both sides
2k/2 = 8/2
k = 8/2
k = 4
When m = 5, k = 4
-------------------------------------------------------------------------------------------------------------------
2k = m + 3
when m = 7
2k = (7) + 3
2k = 10
2k/2 = 10/2
k = 10/2
k = 5
when m = 7, k = 5
------------------------------------------------------------------------------------------------------------------
2k = m + 3
When m = 9
2k = (9) + 3
2k = 12
2k/2 = 12/2
k = 12/2
k = 6
when m = 9, k = 6
-------------------------------------------------------------------------------------------------------------------

Answer:
68
Step-by-step explanation:
4 + (11 - 3)^2
= 4 + 8^2
= 4 + 64
= 68
Answer:
∠x = 63°
Step-by-step explanation:
The exterior angle added with the measure of ∠BAC will equal 180, since they will form a straight line, so we can calculate the measure of ∠BAC:
128 + x = 180
x = 52
∠BAC = 52°
The angles in a triangle all add up to 180°, so we can set up another equation to find x:
52 + 65 + x = 180
117 + x = 180
∠x = 63°
Step by step:
3 x 9/10
Turn 3 into a fraction
3/1 x 9/10
Now multiply straight across
3x9=27 and 1x10=10
So you get
27/10 or 27/10 or 2.7
This can also be completed by simply turning 9/10 into a decimal and doing
3 x 0.9 = 2.7
