Answer:

1.) 22+(33+44)

2.) (5+3)+(1+9)

3.) (-a+d)+(-c+b)

Step-by-step explanation:

Associative property of addition: Changing the grouping of addends does not change the sum. For example,

(2+3)+4= 2+(3+4)

No matter how you rearrange the numbers, they will always add to the same amount.

Rectangle RSUT has diagonals that meet at point x.

Stels [109]

Answer:

x=12.5

y=10

Step-by-step explanation:

Properties of rectangle:

Opposite sides are congruent
All angles are right angles
Diagonals bisect each other
Diagonals are of equal length

so from the properties we came to know that diagonals bisects each other and diagonals are of equal length

Given Rectangle RSUT has diagonals that meet at point X.

⇒ $RX=SX=UX=TX=\frac{1}{2}RU=\frac{1}{2}ST$

⇒ $RX=\frac{1}{2}ST$

⇒ $4x=\frac{1}{2}(100)$

⇒ $x=12.5$

Also $XU=RX$

⇒ $(4)(12.5)=5y$

⇒ $5y=50$

⇒ $y=10$

Which equation is equivalent to 16 Superscript 2 p Baseline = 32 Superscript p 3?.

Mrac [35]

The equation which is equivalent to 16 Superscript 2 p Baseline equal to 32 Superscript p 3 is,

$2^{8p}=2^{5p+15}$

<h3>What is equivalent equation?</h3>

Equivalent equation are the expression whose result is equal to the original expression, but the way of representation is different.

Given information-

The given equation in the problem is,

$16^{2p}=32^{p+3}$

Write both the equation in the form of same base number as,

$(2^4)^{2p}=(2^5)^{p+3}$

The power of the power of a number can be written as product of both the numbers. Thus,

$(2)^{4\times2p}=(2)^{5\times(p+3)}\\2^{8P}=2^{5P+15}$

This is the required equation.

Now if the base is the same at both side of the expression, then the powers can be compared. Thus,

$8p=5p+15$

Solve it further to find the value of p as,

$8p-5p=15\\3p=15\\p=5$

Thus the equation which is equivalent to 16 Superscript 2 p Baseline equal to 32 Superscript p 3 is,

$2^{8p}=2^{5p+15}$

Xian and his cousin kai both collect stamps. Xian has 52 stamps, and kai has 76 stamps. The boys recently joined different stamp

Darya [45]

<em><u>Explanation</u></em>

Xian has 52 stamps and Kai has 76 stamps.

Xian's club will send him 16 new stamps per month and Kai's club will send him 12 new stamps per month.

Suppose, Xian and Kai will have the same number of stamps after $x$ months.

So, the total number of new stamps for Xian $= 16x$ and the total number of new stamps for Kai $= 12x$

So, the equation will be......

$52+16x=76+12x\\ \\ 16x-12x=76-52\\ \\ 4x= 24\\ \\ x=6$

Thus, Xian and Kai will have the same number of stamps after 6 months.

The number of stamps for each of them will be: $52+16(6)=148$
