The red lines signify congruency. Meaning, if one angle (say <EFD) is 75 and has one red line and <JAB also has one red line, it means it also equals 75.
Just like <GHF is 130 and has two lines, <JBC also has two red lines, so it also equals 130.

Marco can swim at a speed of 45 m/min. define how long it will take him to swim 200 m he solve the equation 45 times to equal 20
user100 [1]

Answer:

The time taken by Macro to cover 200 m at the speed of 45 meter per minute is 4.44 minutes

Step-by-step explanation:

Given as :

The speed at which Macro swim = s = 45 meter per minute

The total distance cover by Macro = d = 200 meter

Let The time taken by Macro to cover 200 m = t minutes

<u>Now, From formula </u>

Distance = Speed × time

Or, d = s × t

Or, t = \dfrac{d}{s}

Or, t = \dfrac{\textrm 200 meter}{\textrm 45 meter per min }

Or, t = 4.44 minutes

So,  The time taken by Macro to cover 200 m = t = 4.44 minutes

Hence The time taken by Macro to cover 200 m at the speed of 45 meter per minute is 4.44 minutes  . Answer

9.Lawson will pay $612 to three different credit cards: Expert Card, Passport, and US Speedy. He will pay five times as much to
andre [41]

Answer:

$102

Step-by-step explanation:

We need to build a system of equations for this question.

I am going to call x the value Lawson will pay to Expert Card, y the value he will pay to passport and z the value he will pay to US Speedy.

He will pay $612 in all, so x+y+z = 612.

He will pay 5 times as much to Expert Card as US Speedy, so x = 5z.

The passport payment will be only 20% of the total of the other two payments. So y = 0.2(x+z).

Now we have the following system of equations:

1)x+y+z = 612

2)x = 5z

3)y = 0.2(x+z)

And we need to find y.

I will put 2) and 3) at 1). We end up with:

5z + 0.2(5z+z)+z = 612

5z + 1.2z + z = 612

7.2z = 612

z = $85

Knowing z, now we can find y at 3)

y = 0.2(x+z)

y = 0.2(5z+z)

y = 1.2z

y = 1.2(85)

y = $102

Lawson will pay $102 towards the passport credit balance.
