The answer would be 10. Explanation: So basically you add the two complementary angles and set it equal to the whole thing. So it would look like 4x+46=7x+16. Then, you have to solve for x. To do that, subtract the 4x from both sides and the 16 from both sides. That will leave you with 3x=30. Then, divide by 3, and you get an answer of 10. Hope that helped :)
Answer: x = -7 or x = -4
Step-by-step explanation: When an equation has a squared term in it
such as x² + 11x + 28 = 0, it's called a polynomial equation.
The rule for solving a polynomial equation
is to first set it equal to zero, then factor.
Since this equation is already set equal to zero,
our first step is to factor the left side of the equation.
To factor x² + 11x + 28, we need the factors
of 28 that add to 11 which are 7 and 4.
So we have (x + 7)(x + 4) = 0.
Whenever two terms are multiplied together to equal zero,
this means that either one or the other must equal zero.
So if (x + 7)(x + 4) = 0, then either x + 7 = 0 or x + 4 = 0.
Solving each equation from here, we get x = -7 or x = -4.
So our solution is {-7, -4}.
missing number is 8. there is a pattern with the input and output numbers.
Answer:
3,717,000
Step-by-step explanation:
The calculation of paperback copies is shown below:-
Let us assume hardback copies is x, so paperback copies will be 9x
now the equation is
35,000 + x + 9x = 448,000
10x = 448,000 - 35,000
10x = 413,000
= 41,300
Therefore, the paperback copies are
= 
= 3,717,000
Hence, the paperback copies is 3,717,000
Step-by-step explanation:
what is the problem ? find the slope of the line ?
the slope is the ratio y/x of the y difference and the x difference between 2 points.
I see 2 points with seemingly integer coordinates.
one point is at (2, 6) as you marked it also on the sheet.
the other point is (6, 12).
so, when you go from point 1 to point 2, x changes by 4 units (from 2 to 6) and y changes by 6 units (from 6 to 12).
therefore, the slope is 6/4 = 3/2
