Answer:
66 pieces of candy.
Step-by-step explanation:
First I set up the equation: (c/6)-4 = 7
c represents the candy she started with.
6 represent when she split the candy
4 is the number of pieces she has eaten
7 is the number of pieces she has left
after setting up the equation, you want to add four to the other side to get 11
c/6 = 7+4 --> c/6 = 11
Then you want to multiply by 6 to get ride of the fraction to get a total of 66 pieces of candy.
c = 11 x 6 --> c = 66
Answer:
B, C, D, & E
Step-by-step explanation:
All lines intersect the x axis and y axis so we know B and D are correct. All graphs are in the xy plane unless i (
) is involved, or C. It crosses the center (origin) of the entire plane so it crosses the origin, or E.
Answer:
I would say 1 lbs of dog food is equivalent to 4 4/7 meals.
7/8 lbs : 4 meal = 1 lbs : x meals 1 lbs = 8/8 lbs perform cross 7/8 lbs (x) = 8/8 * 4 7x/8 = 8*4 / 8*1 7x/8 = 32/8 7x/8 = 4 8(7x/8) = 8*4 7x = 32 7x/7 = 32/7 x = 4 4/7 meals to 7/8 : 4 = 1 : 4 4/7 7/8 * 32/7 = 4 * 1 224/56 = 4 4 = 4
Answer:
The total volume is 41.1 cubic meters.
Step-by-step explanation:
Volume of the platform is:
1.8m * 1.8m * 10m = 32.4 m^3
Volume of the ramp is half of a prism with same dimensions as that ramp:
0.5 * 6m * 1.8m * 1.8m = 9.7 m^3
Total: (32.4 + 9.7) m^3 = 41.1m^3
This is a way to factoring trinomials (there exist different equivalent methods).
Multiply the trinomial but the term accompanying . This is the second line. Then, you could take the square of the 
, ant try to create a factor () () that will correspond to the expression in the second line. That is, we want 
In ? we put the corresponding numbers that, if we multiply them we will obtain 42, and if we add them we will obtain 13. This numbers are 6 and 7. Then, we have 
The last step is divide by the number that we multipy in the first step.
