27.6/2.3 = 12 bags of trail mix

2.3 oz per bag, so for x bags you have 2.3x oz total.
The total amount is given as 27.6 oz, so you have 27.6=2.3x.
<em>set equation </em>27.6=2.3x
<em>simplify by dividing both sides by 2.3 </em>\frac{27.6}{2.3}=\frac{2.3x}{2.3}
solution: x=\frac{27.6}{2.3}=12

Find the length of CU, the triangles are similar.
Otrada [13]

Answer:

CU = 117

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

\frac{WC}{WU} = \frac{CD}{UV}

substituting in values to the ratios

\frac{26}{36x-1} = \frac{24}{132} ( cross- multiply )

24(36x - 1) = 3432 ( divide both sides by 24 )

36x - 1 = 143 ( add 1 to both sides )

36x = 144 ( divide both sides by 36 )

x = 4

CU = 36x - 1 - 26 = (36 × 4) - 27 = 144 - 27 = 117

I feel like it’s either answer 2 or 4. i just don’t understand the -9 part
harina [27]

Answer:

n < 27

Step-by-step explanation:

let the number be n

\frac{1}{3} n - 3 < 6 \\ add \: 3 \: to \: both \: sides \\  \frac{1}{3}n - 3 + 3  <  6 + 3 \\  \frac{1}{3} n  <  \\  9 \\ multiply \: both \: sides \: by \: 3 \\  \frac{1}{3} n  \times 3< 9 \times 3 \\ n < 27

The equation
faust18 [17]

Answer:

best approximate is 78 F. to find x, count number of hours between 5 am and 2 pm (which is 9). Substitute 9 into the equation and solve. hope this helps!

Step-by-step explanation:

y = -  0.37 {x}^{2} + 6.15x + 52.3  \\ y =  - 0.37 ({9}^{2} ) + 6.15(9) + 52.3 \\ y =  - 0.37(81) + 6.15(9) + 52.3 \\ y =  - 29.97 + 55.35 + 52.3 \\ y = 77.68

Len and Faye live 54 miles apart. At the same time, they start biking toward each other on the same road. Len's constant rate is
Aloiza [94]

Answer:

Step-by-step explanation:

Len and Faye live 54 miles apart. At the same time, they start biking toward each other on the same road. Len's constant rate is 7 mph and Faye's is 11 mph. How many hours will it take them to meet? [Remember: D = (r)(t)]

 Answer – 3 hours

 D = (r)(t), Where

‘D’ is the distance covered

‘r’ is the approach rate

‘t’ is the total time spent

 Distance covered, ‘D’ =  miles

Approach rate, “r” = mph + mph 7+11

r =  18

t is unknown

 Solving for t,

 D = (r)(t)

54 = 18t

t = 54/18

t = 3 hours
