Answer:
3 boxes
Step-by-step explanation:
First, we find how many cubes are in each box, then we find how many boxes you need for 140 cubes.
<u>To find the number of cubes in a box we need to find the volume of the figure</u>
the top is 2 wide and 4 long so there are 8 cubes on each layer. Sense it is 8 cubes tall with 8 cubes on each layer the model has 8×8=64 cubes in each box.
<u>Now we divide then round up to find how many full boxes she needs to get 140 cubes or more.</u>
If 1 box has 64 cubes and she needs 140 cubes 140/64=2.187. Now we round up sense he can't buy a fraction of a box and the answer is: She needs 3 boxes
Answer:
y= 3x+4
Step-by-step explanation:
2y-6x=8
add 6x to each side
2y-6x+6x=6x+8
2y= 6x+8
divide each side by 2
2y/2 = 6x/2 + 8/2
y= 3x+4
Answer:
Since =18 is a vertical line, there is no y-intercept and the slope is undefined.
Slope: Undefined
y-intercept: No y-intercept

The intersection of the two equations is (1, 1/5). Since the question is asking for the value of x, x = 1.
The answer is true. An altitude of a triangle is the perpendicular segment from a vertex to the line containing the opposite side.
