PLZ HELP QUICK Which property explains why these two expressions are equal - the commutative, the associative, or distributive property of addition?
1 + (2 + 3) = (1 + 2) + 3

Answer:

3°C > - 2°C

Step-by-step explanation:

Ice cream 1 = - 2°C

Ice cream 2 = 3°C

Lower temperatures are colder (cooler) than higher temperature values.

Hence, ice cream at - 2°C is cooler than ice cream at 3°C.

Hence, a temperature of 3°C is higher (greater) than - 2°C. Hence - 2°C is cooler (colder) than 3°C

Hence,

3°C > - 2°C

Answer:

A)53.25

B)35.5

Step-by-step explanation:

86-15=71

add his times and hers

3+1=4

71/4=17.75

17.75*3=53.25

53.25-17.75=35.5

Answer: 46 years old

Step-by-step explanation: If Devaughn is 13 years younger than Sydney,

we can represent Sydney's age as x and Devaughn's age as x - 13.

Since the sum of their ages is 79, we have x + x - 13 = 79.

This simplifies to 2x = 92.

Dividing both sides by 2, we have x = 46.

So sydney is 46 years old.

Answer - A=58 degrees round to the nearest tenth is 60 degrees.

Answer:

terminating

Step-by-step explanation:

if the given fraction is terminating then prime factors of denominator should be 2^n x 5^m where m and n are whole number

5=1x5=2^0x5^1

so it is of form 2^nx5^m

The required, ΔPQS = ΔRQS by SAS (Side-Angle-Side) postulate. Option A is correct.

In geometry, two figures are congruent if they have the same shape and size, and all their corresponding parts (sides, angles, and vertices) are congruent. Congruent figures can be moved, rotated, or reflected without changing their shape or size.

Here,
To prove that ΔPQS = ΔRQS, we need to show that two pairs of corresponding sides and one pair of corresponding angles are congruent.

Looking at the diagram, we can see that:

PQ = RQ (corresponding sides)
PQ = RQ (common side)
∠PQS = ∠RQS (common angle)

To prove that the two triangles are congruent, we can use the SAS (Side-Angle-Side) postulate, which states that if two pairs of corresponding sides and one pair of corresponding angles are congruent in two triangles, then the triangles are congruent.

Therefore, the answer is (A) SAS.

Answer: 1- a square has 4 equal sides so if one side is 9cm then the rest are 9cm, so 9x4= 36cm

2- do the same thing as part 1 but add a power of 2 to it, so 36^2 = 1296cm

Answer:

y=6

Step-by-step explanation:

75-3.5y-4y=4y+6

combine like terms)

75+(-3.5y-4y)=4y+6

75-7.5y=4y+6

add 4y to each side to combine the terms) 75+(-7.5y-4y)=6

75-11.5y=6

subtract 75 from each side to isolate the variable) -11.5y=-69

divide by -11.5 to isolate the variable) -11.5y/-11.5=-69/-11.5

y=6

Answer:

11. y=2x-1

11a. you subtract 2 from the y and 1 from the x and draw your points accordingly to go down or you add 2 to the y and add 1 to the x to go up and plot the points accordingly or you could just draw a graph like i did if you dont wanna do it by math lol. :)

Answer:

Step-by-step explanation:

1). By definition of an exterior angle of a triangle,

  Measure of exterior angle of a triangle is equal to the sum of opposite two interior angles.

  From the figure attached,

  m∠4 = m∠1 + m∠2

2). Property of a triangle states that " sum of interior angles of a triangle is 180°"

   Therefore, m∠1 + m∠2 + m∠3 = 180°

Answer: 75+50x= 105+35x , required equation.

Step-by-step explanation:

Let x = Number of days

Given:  Company "A" charges $75 plus a $50 a day.

Total charge = 75+50x

Company "B" charges $105 plus $35 a day.

Total charge = 105+35x

When both are same , equation becomes

75+50x= 105+35x

So, Required equation: 75+50x= 105+35x

Answer:

∛-27 or -3

Step-by-step explanation:

I don't think you can do anything further to this problem unless we have to solve for something.

If it is 3 square root of the whole thing, then the answer is -3 because

-3 x -3 x -3 = -27

-3 x -3 = negative x negative = positive = 9

9 x -3 = positive  x negative = negative = -27

Answer:

it is the right triangle

Step-by-step explanation:

A set of three integers that can be the length of the sides of a right triangles

Answer:

Yes

Step-by-step explanation:

This is what I think:

This is because the hypotenuse of the triangle is 45m.

27 ^2 + 36 ^2 = 2025

2025 SQAURE ROOT IS 45.

So the square root of the two other measurements squared must be equal to the hypotenuse.

Answer:

100 sq m

Step-by-step explanation:

if you fill in the shape to be a big rectangle it will be 8 x 22 =176 sq m

then the little piece on the left that is taken out is 2 x 2 = 4 sq m

the piece on the right is 6 x 12 = 72 sq m

so subtract them from the big rectangle

176 - 4 - 72 = 100 sq m

Answer:

100m^2

Step-by-step explanation:

To do this we need to break the shape into sections as illustrated in the picture I attached, I color coded the squares to make it easier to explain. Now we just find the area of each shape and add them all together.

Area= base•height

So for the purple shape:

6•2=12

Orange:

8•8=64

Green:

2•12=24

In total:

12+64+24=100

And since it's area it would be in square units which just means it'd look like this:

[tex] {100m}^{2} [/tex]
