Apply the properties of operations to find equivalent expressions for finding the total cost of the clothes

The total cost = 4x + 2y

The total cost = 2y + 4x

The total cost = 6x + 4y

The total cost = 4y + 6x

Step-by-step explanation:

* Lets explain how to solve the problem

- Meredith bought 4 T-shirts and 2 pairs of pants

∴ The number of T-shirts is 4

∴ The number of pairs of pants is 2

- x is the cost of one T-shirt and y is the cost of one pair of pants

∴ The cost of each T-shirt is x

∴ The cost of each pair pf pants is y

∵ The total cost is the sum of the products of the number of T-shirts

  and the cost of each one and the number of pair of pants and the

  cost of each one

∴ The total cost = (4 × x) + (2 × y)

∴ The total cost = 4x + 2y

- To find the equivalent expression switch the places of x and y

∴ The total cost = 2y + 4x

- Meredith bought 6 T-shirts and 4 pairs of pants

∴ The number of T-shirts is 6

∴ The number of pairs of pants is 4

∴ The total cost = (6 × x) + (4 × y)

∴ The total cost = 6x + 4y

- To find the equivalent expression switch the places of x and y

∴ The total cost = 4y + 6x

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

)=3(6x−9)−8

7x+(8)(x)+(8)(

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.
