To find the answer, you need to solve for b.

2(2b + 3) = 12 divide both sides by 3
2b + 3 = 6 divide both sides by 2
2b = 3 subtract 3 from both sides
b = 1.5 divide both sides by 2

b = 1.5 satisfies the equation. if you plug 1.5 in, you get that the equation is true.

Answer:

Everyone is simplifying too far. The answer is A. b = (-3 +- 2 square root 3) / 2

Step-by-step explanation:

+-square root 3 - 3/2 is correct but that is not one of the options.

The sum of 2 fractions is 5/6. Their difference is 1/2. Their least common denominator is 6. The denominator of one is twice the

valentinak56 [21]

Answer:

Step-by-step explanation:

Alright, lets get started.

Suppose the first fraction is : $\frac{a}{b}$

Suppose the second fraction is : $\frac{c}{d}$

The sum of both fraction is given as : $\frac{5}{6}$

$\frac{a}{b}+\frac{c}{d}=\frac{5}{6}$ .......................equation (1)

The difference of both fraction is given as : $\frac{1}{2}$

$\frac{a}{b}-\frac{c}{d}=\frac{1}{2}$ .........................equation (2)

Adding equation (1) and equation (2)

$\frac{c}{d} \ will \ be \ cancelled$

$\frac{2a}{b}=\frac{5}{6}+\frac{1}{2}$

making common denominator

$\frac{2a}{b}=\frac{5}{6}+ \frac{3}{6}$

$\frac{2a}{b}=\frac{8}{6}$

Hence,

$\frac{a}{b}=\frac{2}{3}$

Plugging the value of $\frac{a}{b}$ in equation (1)

$\frac{2}{3}+\frac{c}{d}=\frac{5}{6}$

Subtracting $\frac{2}{3}$ in both sides

$\frac{c}{d}=\frac{5}{6}-\frac{2}{3}$

$\frac{c}{d}=\frac{1}{6}$

Hence both fractions are $\frac{2}{3} \ and \ \frac{1}{6}$ ...................Answer

Answer:

11.82 kilometers in Luis's journey in total

Step-by-step explanation:

As per the statement:

To visit his grandmother

Distance Luis takes a train 6.37 kilometers

Distance Luis takes a car 5.45 kilometers.

We have to find the total distance.

$\text{Total distance} = \text{distance by train}+\text{distance by car}$

Substitute the given values we have;

$\text{Total distance Lui's journey} = 6.37+5.45 = 11.82$ km

Therefore, 11.82 kilometers in Luis's journey in total
