Together a refrigerator and a desk cost $216. Find the price of each if the refrigerator costs three times as much as the desk

Answer:

3a^2b - 2ab^2 + 8ab

Step-by-step explanation:

just add the like terms

a^b + 2a^2b - ab^2 -ab^2 + 8ab

3a^2b - 2ab^2 + 8ab

The ​addition of the expressions a²b - ab² + 8ab and 2a²b - ab² will be 3a²b - 2ab² + 8ab.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

The expressions are given below.

a²b - ab² + 8ab and 2a²b - ab²

The ​addition of the expressions a²b - ab² + 8ab and 2a²b - ab² will be given as,

⇒ a²b - ab² + 8ab + 2a²b - ab²

⇒ 3a²b - 2ab² + 8ab

The ​addition of the expressions a²b - ab² + 8ab and 2a²b - ab² will be 3a²b - 2ab² + 8ab.

Answer:

If the minimum is 10 and it costs $45 for that you would be going into the negatives as $25 is less then $45 meaning : You do not have enough money to purchase something that is $45. You would need $20 more dollars. If there was no minimum you would only be able to buy 4 with a few dollars left over.

Answer:

the answer to that would be 0.

Step-by-step explanation:

Step-by-step explanation:

Hey there!!!

When you closely see in figure, we find that,

90° and (2y + 5)° are supplementary,

So, 90° + 2y +5°=180° { supplementary angle is always 180°}.

or, 2y = 180°-95°

[tex]y = \frac{85}{2} [/tex]

Therefore the measure of angle y is 42.5°.

Again, (5x-17)° + (3x - 11)° = 180° (They are linear pair).

8x - 28° = 180°

8x = 180°+28°

[tex]x = \frac{280}{8} [/tex]

Therefore the measure of angle x is 26°.

Hope it helps...

Answer: x =168

Step-by-step explanation:I think it would be 80 plus 88 so its 168.  

Answer:

q = 12/13

Step-by-step explanation:

Step 1: Write equation

1 - (13q - 5) = -6

Step 2: Solve for q

Distribute -1: 1 - 13q + 5 = -6

Combine like terms: 6 - 13q = -6

Subtract 6 on both sides: -13q = -12

Divide both sides by -13: q = 12/13

Answer:

A = 21 degrees

Step-by-step explanation:

Here in this question, we are told to calculate the value of angle A.

When two angles are tagged complementary, what this means is that the addition of both angles gives a total of 90 degrees.

Hence;

A + B = 90

This means that;

(x-21) + (2x -15) = 90

x + 2x -21-15 = 90

3x -36 = 90

3x = 90+ 36

3x = 126

x = 126/3

x = 42

But we are told to calculate the measure of A

A = x -21

A = 42-21

A = 21 degrees

Answer:

21

Answer:

y = 2x-3

Step-by-step explanation:

We can use those 2 points given to solve for the slope (m) and for the y-intercept (b) in the equation y = mx+b

Slope:

(3,3) and (4,5)

m = [tex]\frac{y2-y1}{x2-x1}[/tex]

m = [tex]\frac{5-3}{4-3}[/tex]

m = 2

Y-intercept:

y = 2x+b

3 = 2(3) +b

3 = 6+b

b = -3

equation: y = 2x-3

Answer:

No.

Step-by-step explanation:

A composite number has factors in addition to one and itself. The numbers 0 and 1 are neither prime nor composite. All even numbers are divisible by two and so all even numbers greater than two are composite numbers. All numbers that end in five are divisible by five. Therefore all numbers that end with five and are greater than five are composite numbers.

Answer:

x=9.5, y=5.75

Step-by-step explanation:

2x-5=14, 3x+2y=40

focus on 2x-5=14 first:

2x-5=14 (add 5 to both sides) 2x=19(divide both sides by 2) x=9.5

Now subtitute x into the second equation and find y:

3(9.5)+2y=40(simplify) 28.5+2y=40(subtract 28.5 on both sides) 2y=11.5(divide both sides by 2) y=5.75

exterior angle = 18°

to find the number of sides of a polygon:

the formula would be:

360 =  exterior angle

 n

360 =  18

 n

n = 360/18

n = 20

therefore, the number of sides of a polygon is 20
