nekit [7.7K]

Answer:

$160.14

Step-by-step explanation:

15% of 174.45 = 26.16

174.45 - 26.16 = 148.28

8% of 148.28 = 11.86

148.28 + 11.86 = 160.14

Distributive property Use the distributive property to remove the parentheses .{y+10}12=
malfutka [58]

Answer:

12y + 120

Step-by-step explanation:

<u>First of, what is the distributive property?</u>

The distributive property is the property that helps distribute numbers under the parenthesis.

For example, lets use {x+1}4. You distribute the 4 towards the x and the one like this:

4(x) + 1(4)

4x + 4

Now, let's go back to your problem

<u>Solution:</u>

{y+10}12

12(y) +12(10)

= 12y + 120

A quadrilaterals consecutive angles measure (3x+10), (9x+50), (4x), and (13x+10). Determine the value of x.
LuckyWell [14K]

The value of x is 10

Step-by-step explanation:

We know that the sum of internal angles of a quadrilateral is 360 degrees

So,

Given

Angle 1 = A1 = 3x+10

Angle 2 = A2 = 9x+50

Angle 3 = A3 = 4x

Angle 4 = A4 = 13x+10

So,

A_1+A_2+A_3+A_4 = 360\\(3x+10)+(9x+50)+(4x)+(13x+10) = 360\\3x+10+9x+50+4x+13x+10 = 360\\3x+9x+4x+13x+10+50+10 = 360\\29x+70 = 360

Subtracting 70 from both sides

29x+70-70 = 360-70\\29x = 290

Dividing both sides by 29

\frac{29x}{29} = \frac{290}{29}\\x = 10

Hence,

The value of x is 10
