The GCF of 16 and 40 is 8.

16/8 = 2

40/8 = 5

We can rewrite this using the distribute property like so:

Using the distributive property:

16 + 40

16 + 40 = 56

We can also add inside the parentheses and multiply and we'll get the same answer.

Apply the properties of operations to find an equivalent expression for finding the total cost of the clothes.

levacccp [35]

Answer:

Total cost of the clothes = 4x + 2y

Total cost of the clothes = 2y + 4x

B. Total cost of the clothes = 6x + 4y

Total cost of the clothes = 4y + 6x

Step-by-step explanation:

Meredith bought 4 T-shirts and 2 pairs of pants. If x is the cost of one T-shirt and y is the cost of one pair of pants, she’ll have to multiply the number of T-shirts by x and the number of pants by y to find the total cost of the clothes.

Write an expression for finding the total cost of the clothes?

Apply the properties of operations to find an equivalent expression for finding the total cost of the clothes?

B. Write an expression for finding the total cost of the clothes if Meredith bought 6 T-shirts and 4 pairs of pants. Also write an equivalent expression for that expression?

Let

x = cost of one T-shirt

y = cost of one pair of pants,

Total cost of the clothes = 4x + 2y

Equivalent expression for finding the total cost of the clothes?

Switch the cost of T-shirt and cost of one pair of pants

Total cost of the clothes = 2y + 4x

B. Total cost of the clothes = 6x + 4y

Equivalent expression for finding the total cost of the clothes?

Total cost of the clothes = 4y + 6x

There is a bag filled with 5 blue and 4 red marbles.

babunello [35]

Answer: 40/81

===========================================

Work Shown:

B = selecting 1 blue

R = selecting 1 red

P(B) = 5/9, since there are 5 blue out of 5+4 = 9 total

P(R) = 4/9, since there are 4 red out of 9 total

P(2 blue) = P(B)*P(B) = (5/9)*(5/9) = 25/81

P(2 red) = P(R)*P(R) = (4/9)*(4/9) = 16/81

The last two equations are valid because we are sampling with replacement. Each selection is independent.

-------------------

P(2 same color) = P(2 blue OR 2 red)

P(2 same color) = P(2 blue) + P(2 red)

P(2 same color) = 25/81 + 16/81

P(2 same color) = (25+16)/81

P(2 same color) = 41/81

-------------------

P(2 different color) = 1 - P(2 same color)

P(2 different color) = 1 - 41/81

P(2 different color) = 81/81 - 41/81

P(2 different color) = (81-41)/81

P(2 different color) = 40/81

Which composition of transformations will create a pair of similar, nol congruent triangles?

Andrej [43]

Answer:

Rotation then dilation.

Step-by-step explanation:

Dilation changes the size. So the result is a similar not congruent triangle. The other transformations move the figure around on the plane.

Answer:

Step-by-step explanation:

We are dealing with similaraty and similar shapes length are in proportion so we are going to set up an proportion.

Length of left triangle small side/ Length of left triangle long side= length of right triangle small side/length of right triangle long side
