Determine whether a triangle can be formed with the given side lengths.

Shtirlitz [24]

Answer:

After 5 months the cost of the two phones and monthly service be the same.

Step-by-step explanation:

1st service cost = $50 + $40x, where "x" represents the number of months

2nd service cost = $50x

Now we have to find the number of months the cost of the two phones and monthly service be the same.

Now we have to equivate and find the value of x.

50x = 50 + 40x

Subtracting 40x from both sides, we get

50x - 40x = 50 + 40x - 40x

10x = 50

Dividing both sides by 10, we get

x = 50/10

x = 5

After 5 months the cost of the two phones and monthly service be the same.

Hope you will understand the concept.

Thank you.

Answer:

106 - 8h = 34

Whenever a math question says "when h = 9," they mean you substitute this number where h is in the equation.

106 - 8(9) = 34

106 - 72 = 34

34 = 34

This means the fact that h = 9 is a solution for h.

I hope this helps! I would really appreciate it if you would please mark me brainliest! Have a blessed day!

What is the solution to the proportion x\45 = 8/18 a.x =16 b.x =20 c.x =35 d.x =101.25

exis [7]

Give the solution proportion of the given number
=> x : 45 = 8 : 18
=> Let’s start solving the proportion
=> 45 * 8 = 360
=> 360 / 18 =20
Thus the answer is letter B. X = 20
let’s check if we have correct answer
=> 20 * 18 = 360
=> 360 / 45 = 8
=> 20 * 18 = 360
=> 360 / 8 = 45
Thus, we have the same answer.

<h3>✒️ACCELERATION</h3>

=================================

$\large\sf\underline{Problem:}$

Calculate the acceleration of riding her bicycle in a straight line that speeds up from 4 m/s to 12 m/s in 10 seconds.

=================================

$\large\sf\underline{Answer:}$

$\qquad \qquad \huge \rm = 0.8 \: m/s²$

=================================

$\large\sf\underline{Solution:}$

Here we have a given of,

$\tt{(12\:m/s) \:= \:V_f = (final\: velocity) }$
$\tt{(4\:m/s)\:=\:V_i = (initial \: velocity) }$
$\tt{(10\:sec) \:=\:T = (elapsed time) }$

$\bold{Formula\:||\: Acceleration = \frac{v\: - \:v_0}{t} = \frac{ΔV}{ΔT} }$

Because acceleration has a direction (riding her bicycle in a straight line), it is important to always subtract the final velocity represented as $\bold{V_f}$ from your initial velocity also represented as $\bold{V_i}$ .
