Rewrite the expression by combining like terms. 3y + 5x2 + 10x + 2x2 + 15x – 3y​

Answer:

1. ∠1 = 120°

2. ∠2 = 60°

3. ∠3 = 60°

4. ∠4 = 60°

5. ∠5 = 75°

6. ∠6 = 45°

Step-by-step explanation:

From the diagram, we have;

1. ∠1 and the 120° angle are corresponding angles

Corresponding angles are equal, therefore;

∠1 = 120°

2. ∠2 and the 120° angle are angles on a straight line, therefore they are supplementary angles such that we have;

∠2 + 120° = 180°

∠2 = 180° - 120° = 60°

∠2 = 60°

3. Angle ∠3 and ∠2 are vertically opposite angles

Vertically opposite angles are equal, therefore, we get;

∠3 = ∠2 = 60°

∠3 = 60°

4. Angle ∠1 and angle ∠4 an=re supplementary angles, therefore, we get;

∠1 + ∠4 = 180°

∠4 = 180° - ∠1

We have, ∠1 = 120°

∴ ∠4 = 180° - 120° = 60°

∠4 = 60°

5. let the 'x' and 'y' represent the two angles opposite angles to ∠5 and ∠6

Given that the two angles opposite angles to ∠5 and ∠6 are equal, we have;

x = y

The two angles opposite angles to ∠5 and ∠6 and the given right angle are same side interior angles and are therefore supplementary angles

∴ x + y + 90° = 180°

From x = y, we get;

y + y + 90° = 180°

2·y = 180° - 90° = 90°

y = 90°/2 = 45°

y = 45°

Therefore, we have;

∠4 + ∠5 + y = 180° (Angle sum property of a triangle)

∴ ∠5 = 180 - ∠4 - y

∠5 = 180° - 60° - 45° = 75°

∠5 = 75°

6. ∠6 and y are alternate angles, therefore;

∠6 = y = 45°

∠6 = 45°.

Answer:

A=630 in^2

Step-by-step explanation:

Triangles: there are two equal triangles so we can treat them as one rectangle

A = 15 * 14 = 210

Rectangle:

A=30 * 14 = 420

A_total = 210 + 420 = 630 in^2

Answer:

(1,2)

Step-by-step explanation:

So, if y= 2x...

2x= 8x-6

-6x= -6

x= 1

y=2x

y= (2)(1)

y=2

Answer: 9 x + 7 /2

Step-by-step explanation:

Answer:

 8 + 9x

Step-by-step explanation:

This is an algebraic expression.  Our job here is to simplify it by combining like terms:  combine the x terms and then combine the constants:

-3x + 5 ¾ + 12x - 2.25, after combining the x terms, is

       5 ¾ +    9x - 2.25

Next, combine the constants.  It's easier to convert -2.25 to -2 1/4 and then

add this 2 1/4 to 5 3/4:  

             8 + 9x

Answer:

12x² + 17x - 5

Step-by-step explanation:

Given

(3x + 5)(4x - 1)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(4x - 1) + 5(4x - 1) ← distribute parenthesis

= 12x² - 3x + 20x - 5 ← collect like terms

= 12x² + 17x - 5

Answer:

3x + 1

Step-by-step explanation:

5x + 2 × 2 = 10x + 4

do this take 16x - 6

you get 6x + 2

then divide by 2 to get the answer 3x+1

Answer:

w = 3x - 5

Step-by-step explanation:

Perimeter of a rectangle formula:

P = 2(l + w)

16x - 6 = 2(5x + 2 + w)

16x - 6 = 10x + 4 + 2w

2w = 16x - 6 - 10x - 4

2w = 6x - 10

w = 3x - 5

Step-by-step explanation:

Answer:

(k - 4) ÷ 9

(k - 4) / 9

Step-by-step explanation:

k decreased by 4 = k - 4

quotient of k decreased by 4 and 9

= (k - 4) ÷ 9 (using division sign)

Or

= (k - 4) / 9 (as a fraction)

Answer:

15 customers

Step-by-step explanation:

Given data

Total Number of customers= 25

60% of 25 customers made an additional purchase

Hence the number of customers that made additional purchase is

=60/100*25

=0.6*25

=15customer

Hence 15 customers made additional purchase

9514 1404 393

Answer:

  Birr 1341.67

Step-by-step explanation:

The tax is 15% of the price (p), so we have ...

  0.15p = 175

  p = 175/0.15 = 1166.67

When the tax is added, the total comes to ...

  1166.67 +175 = 1341.67

The man actually paid Birr 1341.67.
