I’m trying to do that too and I need an answer haha can someone please help us
Answer:
576 million dollars
Step-by-step explanation:
well, 4/5 of 40 hours is 32 hours. so you multiply 32 hours a week by 18 million per hour you get 576 million dollars that week.
2y-1.5y=2
0.5y=2
y=1
10x-5x=4
x=4/5
First, you find the total of both sides.
42 + 67 = 109
Next, you divide the Total by either of the sides, but since we're looking for the percentage of males, it'd be better to do this.
42/109 = 0.39
Multiply it by 100 to change it into percentage form.
0.39 x 100 = 39%
There your answer is 39%
I think that you assumed that:
2k - 1 = k + 2
However we can't do this, because a square has 4 sides whilst a triangle only has 3 sides.
This means that we can say
4(2k - 1) = 3(k + 2)
We multiply by 4 due to 4 sides of the square, and by 3 due to the 4 sides of the triangle.
Lets expand the brackets, and solve it:
4(2k - 1) = 3(k + 2)
8k -4 = 3k + 6
5k -4 = 6 ( subtract both sides by 3x to collect the x values)
5k = 10 (add both sides by 4 to get the x's alone)
k = 2 (divide both sides by 5 to get what just x is)
So k = 2 units
