Answer: A) 32÷6x5=S
B) 30 sheets of chart paper.
Step-by-step explanation:
we have 32 students.
he puts 6 students into each group.
he gives each group 5 pieces of chart paper.
32/6 will give us the number of groups
32/6 = 5.33
This means that we have 5 complete groups 6 students, and one group with 2 students. (a total of 6 groups)
And each of these groups need 5 pieces of paper, so we have the equation:
(32/6)*5 = S
and S = 26.66
now, for the 5 complete groups we need 5 pieces of paper for each, and 5*5 = 25 pieces of papper.
For the group of 2 persons we have the oter 1.66 ( or 2 if we round up) pieces of papper.
but this is a group, so they also should receive 5 pieces of papper regardless that they are only 2 integrants, then the total number of paper pieces is 30.
Answer:
x=6
Step-by-step explanation:
Since this is a right triangle we can use the Pythagorean theorem
a^2 + b^2 = c^2
where a and b are the legs and c is the hypotenuse
x^2 + (x+2)^2 = (2x-2)^2
FOIL (x+2)^2 = x^2 +2x+2x+4 = x^2 +4x+4
FOIL (2x-2)^2 = 4x^2 -4x -4x+4 = 4x^2 -8x+4
Replacing these in to the equation
x^2 +x^2 +4x+4 = 4x^2 -8x+4
Combine like terms
2x^2 +4x +4 = 4x^2 -8x +4
Subtract 4 from each side
2x^2 +4x +4-4 = 4x^2 -8x +4-4
2x^2 +4x = 4x^2 -8x
Subtract 2x^2 from each side
2x^2 -2x^2+4x = 4x^2-2x^2 -8x
4x = 2x^2 -8x
Subtract 4x from each side
4x-4x = 2x^2 -8x-4x
0 = 2x^2 -12x
Factor out a 2x
0 = 2x(x-6)
Using the zero product property
2x =0 x-6 =0
x =0 x-6+6 = 0+6
x = 0 c=6
Answer:
No
Step-by-step explanation:
A^2+b^2=c^2
8^2+15^2=20^2
64+225=400
289=400
289 does not equal 400 so it is not a right triangle
Answer:
To find distance use this equation and plug the variables you have in it.
Equation: Distance=Rate×Time
Answer: 7 hours.
Step-by-step explanation:
The rental price is 15. Add 5 per hour (5x) and the total must be equal to $50
15+5x=50
Solve for x;
