Answer:

x = 2

Step-by-step explanation:

Given

3x + 8x - 2 = 20 , that is

11x - 2 = 20 ( add 2 to both sides )

11x = 22 ( divide both sides by 11 )

x = 2

A right triangle ABC with right angle at B and base BC is drawn. Length of AB is 12, length of BC is 11.5. A similar right trian
expeople1 [14]

Answer:

Option D is correct.

Length of PQ is 36 unit.

Explanation:

If the measures of two sides in one triangle are proportional to the corresponding sides in the another triangle and their including angles are congruent, then the triangles are similar.

Given: Right angle triangle ABC at B , Length of AB = 12 unit and length of BC = 11.5 unit and in right angle triangle PQR at Q , length of QR = 34.5 unit.

Also it is given that  Angle A is congruent to angle P and angle C is congruent to angle R.

To find the length of QR:

It is given that ΔABC and ΔPQR are Similar triangle

then, by the definition of similar triangle:

\frac{PQ}{AB} = \frac{QR}{BC}

Substitute the value of AB, QR and BC to solve for PQ;

\frac{PQ}{12}=\frac{34.5}{11.5} or

PQ = \frac{34.5 \times 12}{11.5}

On simplify:

PQ = 3 \times 12 = 36

Therefore, the length of side PQ is 36 units.

The card that accrues the most interest is the second one, "Cred". To find those amounts multiply the rate by the balance and divide by 12.

The difference between a number b and 7.4 is -6.8
Lera25 [3.4K]

Hello from MrBillDoesMath!

Answer:

b = 0.6


Discussion:

The question can be written as

b - 7.4 = -6.8  =>           (now add 7.4 to each side)

b - 7.4 + 7.4 = -6.8 + 7.4 =>       ( note: -7.4 + 7.4 = 0)

b = 0.6

Thank you,

MrB

Vertex and axis of symmetry f(x)=2x^2-16x-17<br> PLEASE HELP
Law Incorporation [45]
The vertex is at (4, -49) and the axis of symmetry is at x= 4.

To find the vertex of this equation, use this method: ( \frac{-b}{2a})

a=2
b=-16

This will help get your x value and the axis of symmetry. To find the y value of the vertex, insert the x value, 4 to get your y value, -49.

A pie was cut into two equal pieces. Each of the pieces of pie was cut into halves again, and each of those smaller pieces was c
Verdich [7]

3/4

Step-by-step explanation:

If you cut a whole pie into two you get two (2) ½ pieces

1 ÷ 2 = ½

When you cut the two ½ pieces into two you get four (4) ¼ pieces;

½ ÷ 2 = ¼

When you cut the four ¼ pieces into two you get 8 1/8 pieces;

¼ ÷ 2 = ¹/8

Therefore the whole pie at this point is made up of 8 ¹/8 pieces. When two (2) of these pieces are eaten we are left with 6 ¹/8 pieces;

8 – 2 = 6

The portion of the pie left therefore is;

6 * ¹/8 pieces

= ⁶/8

= ³/4
