The answer written in scientific notation is B.
Answer:
k= -11
Step-by-step explanation:
Let's simplify step-by-step.
7k−2(3k+1)−9
Distribute:
=7k+(−2)(3k)+(−2)(1)+−9
=7k+−6k+−2+−9
Combine Like Terms:
=7k+−6k+−2+−9
=(7k+−6k)+(−2+−9)
=k + −11
Answer:
x = 16
Step-by-step explanation:
Let the unknown number be x.
Translating the word problem into an algebraic expression, we have;
4x + 9 = 73
4x = 73 - 9
4x = 64
x = 64/4
x = 16
Therefore, the unknown number is 16.
Answer:
slope:7.5, y-intercept:50
Step-by-step explanation:
The basic equation for slope is y=kx+b
In this equation, k stands for slope and b stands for y-intercept.
So in y=7.5x+50, k is 7.5 and b is 50 which equal to slope is 7.5 and y-intercept is 50
We will use the equation 74.06-56.48=? To find the change in prices, aka how much more money was spent. That equals 17.58. So A, Michael spent $17.58 more than Denise.
