Answer:

Step 2: Commutative Property

Step 3: Associative Property

Step-by-step explanation:

According to the Commutative Property of Addition: Two real numbers can be added in either order.

a + b = b + a

Therefore, she used the Commutative Property in Step 2.

In Step 3, she used the Associative Property, in which the grouping of the addends does not change the sum.

What is the image point of (-9,-2) after the transformation T-2,-5

Answers

Answer:

(-11, -7)

Step-by-step explanation:

The original point is (-9,-2)

The transformation you have to do is (x-2 , y-5)

This makes it so that you move the original point 2 units to the left (as a negative sign in the x value is towards the left side where the negative units are) and 5 units downwards (as a negative sign in the y value is on the negative side of the y-axis which is down)

So, your final answer would be (-9-2,-2-5) which is (-11,-7)

Find the surface area of the prism.

Answers

Answer:

326m²

Step-by-step explanation:

Find the area of each side and find the total sum from each individual area:

2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326

So the surface area of the prism is 326m²

Alexis has $115 and he is earning $50 per week at his summer job. Eduardo has $130 and is earning $40 per week at his summer job. Which system of equations could be used to determine how many weeks they must work to earn the same amount?​

Answers

Answer:

Step-by-step explanation:

Alexis earned to equal Eduardo earned in how many weeks

Alexis earned           115 + 50w = Total        w equals weeks

Eduardo earned      130 + 40w = Total        w equals weeks

subtract equations    -15 + 10w =  0

                                            10w = 15

                                             w = 1.5 weeks   they both will have $190

A camera company packs each camera in a cube­shaped box with side lengths of 1/2 ft. Then the company ships the cameras in a container with dimensions of 5 1/2 ft by 7 1/2 ft by 4 1/2 ft. What is the maximum number of camera boxes that will fit in the container?

Answers

The maximum number of camera boxes that can fit in the container is 1485.

What is volume?

Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.

The volume of each camera box is given by the cube of the side length, which is (1/2)³ = 1/8 cubic feet.

The volume of the container is given by multiplying its length, width, and height, which gives:

= 5 1/2 ft x 7 1/2 ft x 4 1/2 ft
= 5.5 ft x 7.5 ft x 4.5 ft
= 185.625 cubic feet

To find the maximum number of camera boxes that can fit in the container, we need to divide the volume of the container by the volume of each camera box:

185.625 cubic feet / (1/8 cubic feet per camera box) = 1485 camera boxes

Therefore, the maximum number of camera boxes that can fit in the container is 1485.

4/5y - 8 = 2/5y + 16

Answers

Answer:

y=60

Step-by-step explanation:

trust

y = 60

Step-by-step explanation:

Step 1: Group all the x terms on the left side of the equation

Subtract y from both sides:

4/5y - 8 = 2/5y + 16

4/5y - 8 - 2/5y = 2/5y + 16 - 2/5y

2/5y - 8 = 2/5y + 16 - 2/5y

2/5y - 8 = 16

Step 2: Group all constants on the right side of the equation

Add 8 to both sides of the equation:

2/5y - 8 = 16

2/5y - 8 + 8 = 16 + 8

2/5y = 16 + 8

2/5y = 24

Step 3: Isolate the x

Multiply both sides by inverse fraction 52

2/5y = 24 5/2

2/5y 5/2 = 24

y = 24 5/2

y = 60
