1. The rent of a condo unit was ₱1,200.00 for one night, to be shared equally by a group of female friends, who will be having t
zhuklara [117]

Answer:

6 girls were there are first

Step-by-step explanation:

use trial and error. divide 1200 by a random number like 10, and see how much they each had to pay. If we guessed 10, then each girl would hypothetically pay 120 pounds. If four girls left, then 1200/6 would be 200 pounds. there was only a 60 pound increase here, not a 400 pound one.

I checked 1200/6 which equals 200 pounds per girl. If 4 girls left, then it would be 600 pounds for the 2 remaining girls. the rent increased from 200 to 600 which is a 400 pound increase.

Ten less than three times the sum of x and seven is twenty-six.
Orlov [11]

Answer:

<u>x = 12</u>

Step-by-step explanation:

10 - 3 ( x + 7 ) = 26

<em>First Step: Distribute</em>

- 3 to ( x + 7 )

=  10 - 3 x - 21 = 26

<em>Second Step: Combine like terms</em>

10 - 21

=  - 11 - 3 x = 26

<em>Third Step: Add from both sides</em>

26 + 11

=  - 3 x = 37

<em>Fourth Step: Divide from both sides</em>

37 / - 3

<u>x = 12</u>

What is the surface area of a cylinder with a diameter of 8 centimeters and a height of 12 centimeters?
Lostsunrise [7]
The formula for this is A=2 \pi rh+2 \pi  r^{2}.  If the diameter is 8 the radius is 4, so filling in accordingly we have A=2 \pi (4)(12)+2 \pi (16) and A=96 \pi +32 \pi which is A=128 \pi and when you multiply in 3.14 you get that A = 401.92 or B above.
