The answer is 3
Add all numbers (21) then divide by 7 (there are seven numbers there)
So the answe is 3
Answer:
$36 left
Step-by-step explanation:
42+37=79
115-79=36
Required expression is x/9 - 7
Answer:
Chemical
Step-by-step explanation:
Notice that if we add the 3 angles in the image, the outcome should be an angle of 180° (the one of the line alone)
With this, we will found that the answer is k = 13
Let's do the math, for the initial information we can write:
(4k - 7)° + 90° + (3k + 6°) = 180°
Where the 90° comes from the right angle, the one written with a little square.
Now we can solve this for k
(4k - 7)° + 90° + (3k + 6°) = 180°
(4k + 3k)° + (-7° + 90° + 6°) = 180°
7°k + 89° = 180°
7°k = 180° - 89° = 91°
k = 91°/7° = 13
So we found that the value of k is 13.
