(7 x 5) - (7 x 3) = 7x( -(
)?

Juan have 7 bill for $1 bills.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Juan has $67 in $5 and $1 bills.

And, He has 19 bills in all.

Now, Let number of $1 bills = x

And, Number of $5 bills = y

Here, Juan has $67 in $5 and $1 bills.

So, We get;

⇒ x + 5y = 67  .. (i)

And, He has 19 bills in all.

So, We get;

⇒ x + y = 19  

⇒ x = 19 - y .. (ii)

Substitute the value of x from (ii) in (i), we get;

⇒ x + 5y = 67

⇒ 19 - y + 5y = 67

⇒ 19 + 4y = 67

⇒ 4y = 67 - 19

⇒ 4y = 48

⇒ y = 12

And, from (ii),

⇒ x = 19 - y

⇒ x = 19 - 12

⇒ x = 7

Step-by-step explanation:

Answer:Inverse operation

Step-by-step explanation: an example is 5 x 5. That equals 25 so take 5 and divide that by 5. Inverse operation is important.  

Here the height and length are the sides of the rectangular wall and we have to find the area.

Area of rectangle is given by:

[tex] = l \times b[/tex]

where l is the length and b is the breadth/width according to the question. Plugging the given values:

[tex] = 110 \times 96 \: {inch}^{2} [/tex]

[tex] = 10560 \: {inch}^{2} [/tex]

The area of the wall is 10560 inch²

Answer:

[tex]3x + y = - 17 - - - eqn(i) \\ 5x - 2y = 13 - - - eqn(ii) \\ by \: elimination \\ (2 \times eqn(i)) + eqn(ii) \\ (6 + 5)x + (2 - 2)y = ( - 34+ 13) \\ 11x = - 21\\ x = - \frac{21}{11} \\ substitute \: for \: x \: in \: eqn(i) \\ - \frac{ 63}{11} + y = - 7 \\ y = - 7 + \frac{63}{11} \\ y = - \frac{ 14}{11} [/tex]

Answer:

Step-by-step explanation:

3 more than 1/3 represents 3 + 1/3 Which would equal 3 and 1/3 or 10/3. This is different than 3 since it equals 9/3. They don’t equal each other due to it being 3 added to 1/3

Answer:

52° and 128°

Step-by-step explanation:

The sum of the angles in a triangle is 180°

So to find the angles, the easiest thing to do is to use that fact.

There is one angle missing in the triangle shown, so to find it you need to subtract (5x-2)° from 180° since the angle is located on a line.

Simplifying that, you get 180°-(5x-2)°.

Now you can use the fact at the top of these instructions.

So you get the equation: 180°=2x°+76°+180°-(5x-2)°

Solving this equation, you get x=26

Plug x into the values that have x in the picture, and you get 52° and 128°

Answer: See explanation

Step-by-step explanation:

1. (x + 6)(x - 4)

x (x - 4) + 6 (x - 4)

x² - 4x + 6x - 24

x² + 2x - 24

2. (2x + 5)(x - 3)

2x (x - 3) + 5 (x - 3)

2x² - 6x + 5x - 15

2x² - x - 15

3. (3x + 2)(2x + 5)

3x (2x + 5) + 2 (2x + 5)

6x² + 15x + 4x + 10

6x² + 19x + 10

4. (2x - 1)(x - 5)

2x (x - 5) + -1 (x - 5)

2x² - 10x + -x + 5

2x² - 10x - x + 5

2x² - 11x + 5

Answer:kathy 0.1. sorry if i am late

Step-by-step explanation:

Step-by-step explanation:

54 = 2 * 3³

72 = 2³ * 3²

To find the GCF of 54 and 72,

we find the highest common powers of their prime factors.

Highest common power for 2: 2

Highest common power for 3: 3²

Hence GCF of 54 and 72 = 2 * 3².

The answer is Option 2.

Answer:

(a-b) = -25

Step-by-step explanation:

(a+b) = -5

a*b=-150

So one of the letters have to be negative as you can only get a negative product from a positive and negative

There is probably a better way to do this, but I just plug in numbers that I think will work

So, (a*b) = -150, (-15*10) = -150

Okay that works so lets try the other one

(-15+10) = -5

This also works, so lets do the third one

(-15-10) = -25
