Dina distributed 120 marbles to three of her friends. Raghu received one-fourth of the marbles. Freya received one - third of the REMAINING marbles. Bineet got half of the REMAINING marbles. Who got the MOST number of marbles?
Answers
120 divided by 4 = 30.
Raghu received 30.
90 remaining,
90 divided by 3 = 30
Frey’s received 30
There are 60 remaining, Bineet got half of the remaining so he now has 30 as well.

Hey there!
5y + 2y + 6 + 2
COMBINE the LIKE TERMS
= (5y + 2y) + (6 + 2)
= 7y + 8
Overall answer: 7y + 8
The QUESTION ANSWER:
Distributive property:
5y + 2(y + 3) + 2
Combining the like terms:
6y - y + 2y + 10 - 4 + 2
Commutative property:
5y + 2 + 6 + 2y
/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
FORMULAS: (for properties for addition)
COMBINING LIKE TERMS:
a + b + a + b
= 1a + 1b + 1a + 1b
= (1a + 1a) + (1b + 1b)
= 1a + 1a + 1b + 1b
= 2a + 2b
DISTRIBUTIVE PROPERTY:
a(b + c)
= a(b) + a(c)
= ab + ac
COMMUTATIVE PROPERTY:
a + b + c
= b + c + a
= c + b + a

Answer:
The first one (5y + 2 + 6 +2y) is Commutative Property.
The second (6y - y + 2y + 10 - 4 + 2) is combining like-terms.
The last one is Distributive Property.

0.400 100
0.505 5
0.449 51
0.530 30
Thus 0.505 is the closest number to 0.5 in decimal terms
As you see the seconds difference is the smallest therefore 0.505 is closest to .0.5

A school band ordered hats for $3 and large T-shirts for $5. They bought 150 items in all for $590. Graph a system of equations to find how many hats and T-shirts the band ordered.
**PLEASE HELP I DONT UNDERSTAND SYSTEM OF EQUATIONS
Answers
The number of hats ordered is; 80 and the number of shirts ordered is; 70.
What is a system of equations?
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Given that the Cost of hats = $3
The Cost of shirts = $5
The total cost of all the items = $590.
Total number of items bought = 150 items.
Let us assume that the number of hats ordered be x.
The number of shirts ordered be y
The equation can formed as;
x+y = 150 -------(1)
3x+5y = 590 ---------(2)
Multiply and subtract eq(2) from eq(1),
3x+3y = 450
-(3x+5y = 590)
-2y = - 140
y = 140/2
y = 70.
Thus, the number of shirts ordered is; 70.
Now Substitute y=70 in eq(1),
x+70 = 150
x = 150-70
x = 80.
Thus, the number of hats ordered is; 80.

If you do it by substitution, you would solve one equation for either variable (the first equation would be easier to solve for either variable) and plug it into the other equation and solve it. So it would look like: y=150-x 3x+5(150-x)=590
If you did it by elimination, you would line the variables in the equations up and make one variable (We'll use x) the opposite of the same variable in the other equation and add the equations together to make the chosen variable cancel out so you could solve for the other variable. So it would look like: 3x+5y=590
+ -5x- 5y=-150
-----------------
-2x=440
x=-220
After you do that, you would plug that answer into one of the original equations and solve for the other variable. So it would look like: -220+y=150
y=370
If you did it by graphing you would simply graph both equations on the same graph and the point that they intersect at would be your answer.
