Answer:
k = -9
Step-by-step explanation:
When a number (coefficient) is next to a letter (variable) that means you multiply. To solve you would to the opposite, which is to divide.
-126 ÷ 14 = -9
So -9 is equal to k.
Hope that helps and have a great day!
Let the second angle = X
The first angle = 2X+42 ( 42 more than 2 times the second angle)
Now you have 2x+42 + x = 90 ( first angle + second angle = 90)
2x + x = 3x
Now you have:
3x +42 = 90
Subtract 42 from both sides:
3x = 48
Divide both sides by 3:
x= 48/3
x = 16
The second angle = 16 degrees.
The first angle = 2(16) + 42 = 32+42 = 74 degrees
Answer: the answer is 28
Step-by-step explanation:
56-28=28
hi
here is the trick
take new value , substract first value, then divise by first value and multiply by 100
so new value = 2.10
first value = 2.45
2.10 -2.45 = - 0.35
-0.35 / 2.45 = - 0.1428
-0.1428 * 100 = - 14.28 %
So decrease is of 14.3 % rounded to the nearest tenth.
