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.
Step-by-step explanation:
0.4, 0.505, 0.449, 0.48 or 0.53?
if A( -3, 8 ) and B( -7, -6 ).
Answer:
(-5,1)
Step-by-step explanation:
x = (-3+(-7)/2 = -10/2 = -5
y = (8 +(-6)/2 = 2/2 = 1
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
The number of hats ordered is; 80 and the number of shirts ordered is; 70.
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.
