Why do the inequality signs stay the same in the last two steps of exercise 1

2 answers:

The only reason an inequality would change would be because a number is divided or multiplied by a negative number. So if it stayed the same, then it would be because there was no division or multiplication by a negative number. Hope I helped :)

The inequality signs stay the same when you multiply or divide a positive number

They only flip if you multiply or divide a negative number (that is in the divisor place)

hope this helps

Antonio finished the race in 28 minutes and 11.00 seconds. Julio finished 0.08 second faster than Antonio. Pete finished 0.1 sec

Answer:

It took Peter 28 minutes and 10.82 seconds to finish the race.

Step-by-step explanation:

We have that:

$t_{A}$ : Antonio = 28 min + 11.00 s (1)

$t_{J}$ : Julio = A - 0.08 s (2)

$t_{P}$ : Pete = J - 0.1 s (3)

Then, the time at which Pete finished the race is:

$t_{P} = t_{J} - 0.1$ (4)

By entering equations (1), (2), (3) into (4) we have:

$t_{P} = (t_{A} - 0.08) - 0.1$

$t_{P} = 28 min + 11.00 s - 0.18 s = 28 min + 10.82 s$

Therefore, it took Peter 28 minutes and 10.82 seconds to finish the race.

I hope it helps you!

I need help with number 2 don’t understand it. someone help plz.

Sholpan [36]

I would say solve each diameter equation and order them fromleast to greatest, for example

1 Venus- 7.52×10 to the power of 3
So first simplify 10 to the power of 3 which is, 1000. Then you multiply 7.52 by 1000 which gets you 7520.

So solve each equation and order it

7x = 6(x+6)

7x = 6x+36

-6x -6x

x = 36
