What would be the equation and how can I solve it

Blababa [14]

If alonzo is x then the equation is

x + (x +3) + 2(x + 3) = 57

Which equals

x + x + 3 + 2x + 6 = 57
4x + 9 = 57
4x = 48
x = 12

This means alonzo is 12 years old and alexis is 3 years older so alexis is 15 years old

Answer = 15 years old

Answer:

see below

Step-by-step explanation:

1. < 4 is the exterior angle of a triangle given

2. <1 + <2 + <3 =180 basic property of triangles

3. <3 + <4 are a linear pair <3 and <4 are adjacent and form a straight line

4. <3 and <4 are supplementary angles supplementary angles are linear pairs

5. <3 + <4 = 180 The definition of supplementary angles are that they add to 180 degrees

6. <1 + <2 + <3 = <3+ <4 Substitute <3 + <4 for 180 in equation from step 2

7 <1 + <2 = <4 Subtract <3 from each side using the subtraction property of equality

The minute hand of a clock is 8 inches long. To the nearest tenth of an inch, how far does the tip of the minute hand travel as

lesya692 [45]

Answer:

The tip of the minute hand travels 20.9 inches.

Step-by-step explanation:

We are given that the minute hand of a clock is 8 inches long. And we have to find that how far does the tip of the minute hand travel as the time progresses from 12:00 to 12:25.

<u>So, firstly we will find the circumference of circle;</u>

Circumference of circle (C) = $2\pi r$ {where r is radius of circle}

= $2 \times \pi \times 8$ {given r = 8 inches long}

= $16 \pi$

Now, as we know that the minute hands completes the full circle in 60 minutes, therefore, the length of the arc between time 12:00 to 12:25 represents $\frac{25}{60}$ which is $\frac{5 }{12}$ of the circumference, that means;
