<h2><em>Solution </em><em>:</em></h2>

<h3>Step by Step explained:</h3>

<h2>1. Multiply the number </h2>

$35 - 12 + \frac{6 - 36}{4 } \\ 35 - 12 + \frac{216}{4}$

<h2>2. Divide the number </h2>

$35 - 12 + \frac{216}{4} \\ 35 - 12 + 54$

<h2>3. Add the numbers </h2>

$35 - 12 + 54 \\ 77$

<h2>Solution : </h2>

Answer:

EF = 22 , AB = 1

Step-by-step explanation:

the midsegment of a trapezoid is equal to half the sum of the parallel bases

EF = $\frac{1}{2}$ (AB + DC ) ← substitute values

x + 6 = $\frac{1}{2}$ (2x - 9 + x + 5) ← multiply both sides by 2 to clear the fraction

2x + 12 = 3x - 4 ( subtract 3x from both sides )

- x + 12 = - 4 ( subtract 12 from both sides )

- x = - 16 ( multiply both sides by - 1 )

x = 16

Then

EF = x + 6 = 16 + 6 = 22

Similarly

EF = $\frac{1}{2}$ (AB + DC ) , that is

x + 3 = $\frac{1}{2}$ (4x - 3 + 2x + 5 ) ← multiply both sides by 2 to clear the fraction

2x + 6 = 6x + 2 ( subtract 6x from both sides )

- 4x + 6 = 2 ( subtract 6 from both sides )

- 4x = - 4 ( divide both sides by - 4 )

x = 1

Then

AB = 4x - 3 = 4(1) - 3 = 4 - 3 = 1

1) A microbiologist measures the length of a bacterium of 0.000163 m and the

sashaice [31]

Answer:

a) The bacterium is longer;

b) The bacterium is 0.1543 mm longer than the yeast.

Step-by-step explanation:

In order to compare the length of the two beings we need to convert them to the same unit. We can do it either way, but we'll choose to convert from meters to milimetres, since we're dealing with small numbers. To do that we need to multiply the length that is in "m" by 1000.

$length_{bac} = 0.000163*1000 = 0.163 \text{ mm}$

a) The bacteria is longer than the yeast.

b) We need to subtract their length in order to find this answer:

$\text{dif} = length_{bac} - length_{yeast}\\\text{dif} = 0.163 - 0.0087 = 0.1543 \text{ mm}$
