I agree with the other persons answer.

Answer:

Step-by-step explanation:

Alberto uses the steps below to solve the equation One-half x minus 3 equals 7. Step 1: One-half x minus 3 plus 3 equals 7 plus 3 Step 2: One-half x plus 0 equals 10 Step 3: One-half x equals 0 Step 4: 2 (one-half) x equals 2 (10) Step 5: 1 x equals 20 Step 6: x equals 20.

Which justifies Step 6 of his work? the addition property of equality the identity property of addition the multiplication property of equality the identity property of multiplication.

1/2x - 3 = 7

One-half x minus 3 equals 7.

Step 1: add 3 to both sides

1/2x - 3 + 3 = 7 + 3

One-half x minus 3 plus 3 equals 7 plus 3

Step 2:

1/2x + 0 = 10

One-half x plus 0 equals 10

Step 3: One-half x equals 10

1/2x = 10

Step 4: Multiply both sides by 2

1/2x * 2 = 10 * 2

2 (one-half) x equals 2 (10)

Step 5:

1x = 20

1 x equals 20

Step 6:

x = 20

x equals 20.

identity property of multiplication states that when 1 is multiplied to an equation, the result remains the same.

identity property of multiplication justifies Step 6 of his work

Answer:

a=37

Step-by-step explanation:

22+15=37

Answer:   The solution is: " a = 37 " .

____________________________

Step-by-step explanation:

____________________________

Given the equation:

 a − 15 = 22  ;  Solve for "a" .

Add "15" to each side of the equation;

to isolate "a" on one side of the equation;  

  and to solve for "a" :

a − 15 + 15 = 22 + 15 ;

  to get:

____________________________  

          →   a = 37 .

absolute values definition

Answer:

31.5 units^2

Step-by-step explanation:

Rectangle area (RA) = l × w

Triangle area (TA) = (bh)/2

RA = 3 × 7

RA = 21

TA = (7 × 3)/2

TA = 21/2

TA = 10.5

(Triangles are congruent as shown by the lines on each side of the triangle so I can calculate area of both of them together as I just did)

Add areas together

21 + 10.5 = 31.5

3 ice cream machines will make a total of 480 gallons for the same length of time

4 ice cream machines will make a total of 640 gallons for the same length of time

From the question,

We are to determine the number of gallons of ice cream that could be made.

From the given information,

2 ice cream machines make a total of 320 gallons in a certain amount of time.

If 2 ice cream machines can make a total of 320 gallons

Then,

3 ice cream machines will make a total of x gallons in the same amount of time

x = [tex]\frac{320 \times 3}{2}[/tex]

x = 480 gallons

Hence, 3 ice cream machines will make a total of 480 gallons.

If 2 ice cream machines can make a total of 320 gallons

Then,

4 ice cream machines will make a total of y gallons in the same amount of time

y = [tex]\frac{320 \times 4}{2}[/tex]

y = 640 gallons

Hence, 4 ice cream machines will make a total of 640 gallons.

FAILURE OF THE SCHOOL SYSTEM

Explanation:

The order of ABC and RPQ is important so we can match up the angles like so

Meaning that angle Q = 75 since angle C is this measure.

Answer:

∠ Q = 75

Step-by-step explanation:

The reason,

As we can see that Triangle ABC is congruent to Triangle RPQ, so that means, ∠A =∠R , ∠B = ∠P , ∠C = ∠Q

And ∠C = 75° which means, ∠Q = 75°

Answer:

5x+2y=36-------(1)

2x+3y=43-------(2)

Now ,

from(1)

5x+2y=36

or, X=(36-2y)/5-------------------(3)

now putting the value of x in eqn ----(2)

72-4y+3y=43

or, 72-43=y

:- Y=29✔️✔️

Again .putting the value of Y in eqn-----(3) we get,

;- X=(36-2×29)/5

or, X=(36-58)/5

or, X=. (-22)/5

X= (-22)/5 or 4.4✔️✔️

Answer:

196, 245, 294

Step-by-step explanation:

sum the parts of the ratio, 4 + 6 + 6 = 15 parts

Divide the total by 15 to find the value of one part of the ratio

735 ÷ 15 = 49 ← value of 1 part of the ratio, thus

4 parts = 4 × 49 = 196

5 parts = 5 × 49 = 245

6 parts = 6 × 49 = 294

4.052×106=4052000

Explanation:

The number is written in scientific notation, where we write a number so that it has single digit to the left of decimal sign and is multiplied by an integer power of 10.

In general notation power of 10 is not used and we multiply the number in single digit by the power of 10 to get it in simple standard decimal notation.

Multiplying by a positive power of 10 means moving decimal to right and in case power is negative (this is when the number is less than 1) it meanss moving decimal to left. This is done by the power of 10.

Here we have

4.052×106= 4.0520000×100000= 4052000.

= 4052000

Answer:

-x + 13

Step-by-step explanation:

x - 2x + 13 =

Combine like terms, x and -2x.

= -x + 13

Answer:

13-x

Step-by-step explanation:

x-2x can alsso mean x(1-2). (1-2)=(-1). So x(-1)=-x.

So now you have -x+13, or to make it shorter, 13-x.

Answer: D

Step-by-step explanation:

To find the perimeter of the square, you want to first find the length of each side. Since the figure is a square, we know that each side is equal to each other. We can set the expressions equal to each other to find x.

[tex]\frac{3}{4}x-1=\frac{1}{2}x+7[/tex]           [subtract both sides by 1/2x]

[tex]\frac{1}{4}x-1=7[/tex]                    [add both sides by 1]

[tex]\frac{1}{4}x=8[/tex]                           [multiply both sides by 4]

[tex]x=32[/tex]

Now that we know x, we can plug it into each expression to find teh length of each side.

[tex]\frac{3}{4}(32)-1[/tex]                       [multiply]

[tex]24-1[/tex]                           [subtract]

[tex]23[/tex]

Now that we know each side is equal to 23, we can add all the sides together to find the perimeter.

23+23+23+23=92        or          23×4=92

Since we know that the perimeter is 92 units, the answer is D.
