Marty was wrong in opening brackets

Answer:

  • Marty is incorrect.

Step-by-step explanation:

<u>Let's check his work by simplifying the given expression.</u>

  • 2(x - 2) - 2(3)
  • => 2x - 4 - 6
  • => 2x - 10

When I compare Marty's result and this result, they are un-equal. Hence, Marty is incorrect.

<u>Marty's mistake</u>

  • Marty must've got the problem wrong because of not understanding the distributive property.
  • He probably forgot to multiply -2 by 2. Instead, he only subtracted 2 when he should've subtracted 4 from 2x.

Using words, explain all steps of dimensional analysis when converting 6.7 hectometers to meters.
9966 [12]
<h2>6.7 hectometers is equal to "670 meters".</h2>

Step-by-step explanation:

We have,

6.7 hectometers

To convert 6.7 hectometers to meters.

We know that,

1 hectometer = 100 meters

⇒ 1 hm = 100 m

∴ 6.7 hectometers

= 6.7 × 100 meters

= 670 meters

∴ 6.7 hectometers (hm) = 670 meters (m)

Thus, 6.7 hectometers is equal to "670 meters".

Alternate interior angles are:
(2x-70) = (x+30)
2x-x = 30+70
x = 100

the angle 5y is supplementary to the other angle.
5y + (100+30) = 180
5y + 130 = 180
5y = 180-130
5y = 50
y = 50/5
y = 10
