Answer:

\bold{\red{\boxed{\blue{ x = 3.9}}}}

Step-by-step explanation:

\frac{2x}{9}  +  \frac{x}{3}  =  \frac{13}{6}  \\  \frac{2x + 3x}{9}  =  \frac{13}{6}  \\  \frac{5x}{9}  =  \frac{13}{6}  \\ use \:  \: cross \:  \: multipication \\ 5x \times 6 = 9 \times 13 \\ 30x =11 7 \\  \frac{30x}{30}  =  \frac{117}{30}  \\ x = 3.9

Answer:

x = 3 9/10

Step-by-step explanation:

2x/9 +x/3 = 13/6

Get a common denominator on the left side

2x/9 + x/3 *3/3 = 13/6

2x/9 + 3x/9 = 13/6

5x/9 = 13/6

Multiply each side by 9/5 to isolate x

5x/9 *9/5 = 13/6 * 9/5

x = 117/30

Divide the top and bottom by 3

x = 39/10

x = 3 9/10

Answer:

  • a)  11, d) 25, e) 14, b) 25, c) 28, f) 33

Step-by-step explanation:

<h3>Given</h3>
  • ΔBDF, with H is the centroid of BDF, DF = 50, CF = 42, and BH = 22
<h3>To find</h3>
  • HE , DE , CH, EF,  HF, BE
<h3>Solution</h3>

As per definition of the centroid, the points C, E and G are midpoints of respective sides and the length of short and long distances from the centroid have ratio of 1/3 and 2/3 of median

  • a) HE =  1/2BH = 1/2(22) = 11
  • d) DE =  1/2DF = 1/2(50) = 25
  • e) CH =  1/3CF = 1/3(42) = 14
  • b) EF =  DE = 25
  • c) HF =  2/3CF = 2/3(42) = 28
  • f) BE =BH + HE = 22 + 11 = 33

The table shows the predicted growth of particular bacterium after various numbers of hours. Write an explicit formula for the s
Oksana_A [137]

Answer:

D

-29

Step-by-step explanation:

Problem 1

In the first hour, the number of bacteria is 22

In the second hour,the number of bacteria is 44

It looks like the formula is some multiple of 22

That means you should pick D

Problem 2

n = 12

a = 15

d = - 4

an= 15 + (n - 1)*d

a12 = 15 + 11*(-4)

a12 = 15 - 44

a12 = - 29
