First, you would do the parentheses which is multiply 4 to -4x to 7 which leave you with the equation 7x-16+28=118. Then you combine the like terms which gives you 7x+12=118. After that you subtract the number 12 to 118 which the next you divide so the answer is 15.14285714285714 and so on which can be simplified to 15.14 or 15.1

As part of his math assignment, Santos has to estimate the height
ycow [4]

Answer:

105.46 feet

Step-by-step explanation:

We know all three angles (60, 90, and 30), as well as one side, which is adjacent to the 60 degrees. We want to find the side opposite to the 60 degree angle. To do this, we can use tangent, utilizing both opposite and adjacent.

Using tan, we can say that tan(60) = x/58, with x representing the height of the lighthouse (minus 5, because Santos is 5 feet tall and he is measuring the angle from the top of his head). Multiplying both sides by 58, we can get that 58 *tan(60) = x = 100.46. Add 5 to that to get 105.46 feet as your answer.

There are 70 people attending a high school baseball game. The difference between the number of women and men at the game is 18.
nata0808 [166]
Adding the systems of equations together, we get
2x=88
Dividing both sides by 2, we get x, or the number of women, to be 44.
Plugging that into either equation, we get
44-y=18. Adding y to both sides and subtracting 18, we get y, or the number of men, to be 26.
