Lesson 7: Solving Equations with Fractions 6th Grade Practice

Mathematics
1 answer:
Nezavi [6.7K]3 years ago
4 0

Answer:

1.C

2. 130, answer not listed

3. A

4. B

5.C

Step-by-step explanation:

To solve equations with fractions, convert from a mixed number to an improper fraction then use the inverse. The inverse of a fraction is multiplying by the reciprocal of the fraction on both sides.

1.

2\frac{1}{4}r=10\\\\\frac{9}{4}r=10\\\\\frac{4}{9} *\frac{9}{4}r=10*\frac{4}{9}\\\\r=\frac{40}{9} \\\\r=4\frac{4}{9}

2.

\frac{h}{26}=5\\\\\frac{26}{1} *\frac{h}{26}=5*\frac{26}{1}\\\\h=130

3.

\frac{6}{7}k=6\\\\\frac{7}{6} *\frac{6}{7}k=6*\frac{7}{6}\\\\k=\frac{42}{6} \\\\k=7

4.

\frac{4}{5}x\\\\\frac{4}{5}*\frac{5}{8}\\\\\frac{20}{40} \\\\\frac{1}{2}

5.

\frac{h}{4/9} \\\\\frac{\frac{16}{3} }{\frac{4}{9} } \\\\\\\frac{\frac{16}{3} *\frac{9}{4}}{\frac{4}{9}*\frac{9}{4}}\\\\\frac{16}{3} *\frac{9}{4}\\\\\\\frac{144}{12} \\\\12

30 people are running for an office to be chosen randomly. You plan to use a 6-sided dice and a spinner. How many sections need
allsm [11]

The number of sections on the spinner so that each person has heir own shape and number is 5

<h3>How to determine the number of sections?</h3>

The given parameters are:

People, n = 30

Die = 6 sided

Let the sections on the spinner be s.

The equation to calculate s is represented as:

People = Die * s

This gives

30 = 6 * s

Divide both sides by 6

s = 5

Hence, the number of sections on the spinner so that each person has heir own shape and number is 5

The power generated by an electrical circuit (in watts) as function of its current x (in amperes) is modeled by: P(x)=-12x^2 +12
Minchanka [31]

Given:

The power generated by an electrical circuit (in watts) as function of its current x (in amperes) is modeled by:

P(x)=-12x^2+120x

To find:

The current that will produce the maximum power.

Solution:

We have,

P(x)=-12x^2+120x

Here, leading coefficient is negative. So, it is a downward parabola.

Vertex of a downward parabola is the point of maxima.

If a parabola is f(x)=ax^2+bx+c, then

Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)

In the given function, a=-12 and b=120. So,

-\dfrac{b}{2a}=-\dfrac{120}{2(-12)}

-\dfrac{b}{2a}=-\dfrac{120}{-24}

-\dfrac{b}{2a}=5

Putting x=5 in the given function, we get

P(5)=-12(5)^2+120(5)

P(5)=-12(25)+600

P(5)=-300+600

P(5)=300

Therefore, 5 watt current will produce the maximum power of 300 amperes.
