Find the area of the room by multiplying the length by the width:
Area of room = 15.5 x 18.5 = 286.75 square feet.
Divide the total area of the room by the area of a box to find the number of boxes needed.
286.75 / 25 = 11.47
Since you can't buy a partial box, round up to the nearest whole number.
You need B. 12 boxes total.
Answer:
13 + 2x = 21 where x is the number of bottles of water
Step-by-step explanation:
pizza plus water = 21
13 + water = 21
Each water is 2 dollars
13 + 2x = 21 where x is the number of bottles of water
Sin is -sqroot3/2, cosine is 1/2, when ever you are given a point, the y value is always sin and x value is always cosine.
Firstly, you've got to expand the brackets, this becomes;
8a-4= -10a+ 50
You've then got to eliminate the -10a and you do this by adding 10a to both sides,
This then becomes 18a-4=50
You've then got to add 4, to eliminate this, which then becomes 18a=54
You've then got to divide both sides by 18, and this becomes 3.
Therefor, a=3
Hope this helps :)
Answer:
y=3x-2 (d)
Step-by-step explanation:
First, we need to look at the y-intercept, we can see that when x = 0, y= -2. So then our equation has to be y=mx+b, and b is -2. next we find our slope, we can see that we go up by 3, then over 1, so our slope is 3/1 or 3. so the final equation is y=3x-2.
Hope this helps!
