Answer:
1 Collect like terms.
5(2x-1)+(30+20)
2 Simplify.
5(2x-1)+50
3 Expand by distributing terms.
10x-5+50
4 Collect like terms.
10x+(-5+50)
5 Simplify.
10x+45
Hope this helps!! <3
<span>P= IRT solve for T
To solve for T, you must get T on it's own on one side of the equals sign, with all the other terms on the other side.
IRT means that I and R are multiplied by T.
To get rid of them we must do the opposite of multiply, which is divide.
But because this is an equation, anything we do on one side of the equals sign, must be repeated on the other side.
So if we divide the right side by IR, we must also divide the left side by IR</span>
Answer:
The length of the sailboat is 80 feet.
Step-by-step explanation:
The function
................ (1)
models the maximum speed s in knots for a sailboat with length l in feet at the waterline.
So, using this model we have to find the length of a sailboat with a maximum speed of 12 knots.
Now, from equation (1) we get
⇒ 
⇒ 
feet (Answer)
{The value is round to the nearest foot}
27 = 2x + 3
