Please help!!!A triangle has one side that measures 9 units, another side that measures x, and a third side that measures 2 units more than x. The perimeter is 29 units.

Which equation would we use to find the value of x?

x + x + 2 = 29
x + x + x + 2 + 9 = 29
x + x + 2 + 9 = 29
x + x + x + 2 = 29

Answers

The right answer is: x + x + 2 + 9 = 29

Step-by-step explanation:

According to given statement,

Side 1: 9 units

Side 2: x units

Side 3: x+2 units

The perimeter of a triangle is given by

$Side1+Side2+Side3=P\n$

Putting the values we get

$(9) + (x) + (x+2) = 29\n9+x+x+2=29\nx+x+2+9=29$

Hence,

The right answer is: x + x + 2 + 9 = 29

Target sells 24 bottles of water for $3, and 36 bottles of water for $4. Which is the better buy and by how much?

Answers

rate
cost/amount
3/24=1/8, 1 doller per 8 botttles

4/36=1/9, 1 dollar=9 bottles

9>8
9-8=1
if by 'better buy' you mean cheaper price then
24 or $3 is better by 1 bottle per bottle

You should NEVER buy plastic water bottles! only the reusable ones, but if you must know, it's cheaper to buy the 24 pack, because if you divide 24 by $3 you get 0.8 for the cost of each water bottle.
If you divide 36 by $4 you get 0.9 for the cost of eact water bottle.

$a) (7)/(100) + (7)/(10) = (7)/(100) + (7*10)/(10*10) = (7+70)/(100) = (77)/(100) \n \n b) (7)/(10) + (70)/(100) = (7*10)/(10*10)+ (70)/(100)= (70+70)/(100)= (140)/(100) \n \n c)(1)/(10) + (17)/(100) = (1*10)/(10*10) + (17)/(100)= (10+17)/(100) = (27)/(100) \n \n d) (1)/(1) + (4)/(00) =(1*100)/(1*100) + (4)/(100) = (100)/(100) + (4)/(100) = (104)/(100) \n \n$

$e) (11)/(100)+ (8)/(10) = (11)/(100)+(8*10)/(10*10) =(11+80)/(100) = (91)/(100)$
