Solve for B. <br><br> A = 3(B + C)

Vanyuwa [196]

This is a literal equation
first, divide 3 on both sides $\frac{A}{3} = \frac{3(B+C)}{3}$
Next, subtract C on both sides $\frac{A}{3} -C=B+C-C$

The answer is $B= \frac{A}{3} -C$

$\sf{3. \ \ Given : \dfrac{2}{3} - \dfrac{5}{4} + \dfrac{7}{2}}$

Let us solve the first two fractions : The LCM of 3 and 4 is 12

$\sf{\implies \dfrac{4(2) - 5(3)}{12} + \dfrac{7}{2}}$

$\sf{\implies \dfrac{8 - 15}{12} + \dfrac{7}{2}}$

$\sf{\implies \dfrac{-7}{12} + \dfrac{7}{2}}$

LCM of 2 and 12 is 12

$\sf{\implies \dfrac{-7 + 7(6) }{12}}$

$\sf{\implies \dfrac{-7 + 42}{12}}$

$\sf{\implies \dfrac{35}{12}}$

$\sf{\implies 2 +\dfrac{11}{12}}$

$\sf{\implies 2 \dfrac{11}{12}}$

---------------------------------------------------------------------------------------

$\sf{4. \ \ Given : \dfrac{(2 - 7)^2 + 5}{3}}$

$\sf{\implies \dfrac{(-5)^2 + 5}{3}}$

$\sf{\implies \dfrac{25 + 5}{3}}$

$\sf{\implies \dfrac{30}{3}}$

$\sf{\implies 10}$

You measure 33 turtles' weights, and find they have a mean weight of 48 ounces. Assume the population standard deviation is 14.1

zepelin [54]

Answer:

Confidence interval = 48±4

Step-by-step explanation:

Given:

Mean X = 48

Standard deviation sd = 14.1

Computation:

Z table value of 90% = 1.645

Total number n = 33

Computation:

Margin of error M.E = Z[sd/√n]

Margin of error M.E = 4 approx.

Confidence interval = 48±4

This may help:

There are $\frac{1}{3}$ gallons of lemonade.

Two friends share the lemonade.

What fraction of the lemonade does each friend receive?

To solve you do kcf or keep change flip.

You keep $\frac{1}{3}$ and change division to multiplication.

Then $\frac{2}{1}$ is changed to $\frac{1}{2}$

<span>The answer would be </span> $\frac{1}{6}$

Hope That Helps!
