Answer:
34 degrees.
Step-by-step explanation:
Assuming AK is a straight line and being shown angle JDK is right and 90 degrees it can be stated that 4x + (3x-8) = 90 degrees.
Drop the parentheses and get 7x - 8 = 90.
Add 8 to both sides 7x = 98.
Divide both sides by 7, x = 14.
Plug that x value into (3x-8), [3(14)-8] = 34 degrees.
Answer:
A and B
Step-by-step explanation:
4(d-2)
4 times d is 4d
4 times -2 is -8
11000000000
1.1 x 10^10
Billion has 9 zeros.
Let this number be x.
"Six less than seven times a number is equal to -20" can be represented by the equation 7x - 6 = -20. We need to solve for x.
First, add 6 from each side so we can have the variables on a side and the numbers on the other:
7x - 6 + 6 = -20 + 6
7x = -14
Then, you divide each side by 7 so we can get the variable x alone on a side, and its value on the other side:
(7x)/7 = -14/7
x = -2
You can re-check your answer (very important):
7x - 6 = 7 (-2) - 6 = -14-6 = -20
