Answer:

\frac{16}{28}

Step-by-step explanation:

Question asked:

Select all of the ratios that are equivalent to 4 to 7.

1) 5/8

2) 12/10

3) 8.14

4) 5 to 10

5) 16/28

6) 9 to 16​

<u>Solution</u>:

To know the ratios are equivalent to \frac{4}{7} or not, we have to check each by cross multiplication:-

1) \frac{5}{8}

\frac{4}{7} =\frac{5}{8} \\ \\

By cross multiplication:

4\times8=5\times7\\ \\ 32=35

Not equivalent.

2) \frac{12}{10}

\frac{4}{7} =\frac{12}{10} \\ \\

By cross multiplication:

4\times10=12\times7\\ \\ 40=84

Not equivalent.

3) 8.14 = \frac{814}{100} \ eliminating\ decimal

\frac{4}{7} =\frac{814}{100} \\ \\

By cross multiplication:

4\times100=814\times7\\ \\ 400=5698

Not equivalent.

4) \frac{5}{10}

\frac{4}{7} =\frac{5}{10} \\ \\

By cross multiplication:

4\times10=5\times7\\ \\ 40=35

Not equivalent.

5)\frac{16}{28}

\frac{4}{7} =\frac{16}{28} \\ \\

By cross multiplication:

4\times28=16\times7\\ \\ 112=112

<em><u>Yes, this is equivalent.</u></em>

6) \frac{9}{16}

\frac{4}{7} =\frac{9}{16} \\ \\

By cross multiplication:

4\times16=9\times7\\ \\ 64=63

Not equivalent.

Thus, only \frac{16}{28} is equivalent.

Write an absolute value inequality that
fiasKO [112]

Answer:

All real numbers greater than or equal to -1 and less than or equal to 2

Step-by-step explanation:

Let

A_1 ------> the area of rectangle

A_2 ----> the area of triangle

we know that

\left|A_1-A_2\right|\le 6

<em>Find out the area of rectangle</em>

A_1=4(x+2)=(4x+8)\ units^2

<em>Find out the area of triangle</em>

A_2=(1/2)(4)(5)=10\ units^2

substitute

\left|(4x+8)-10\right|\le 6

Simplify

\left|4x-2\right|\le 6

<em>First case (positive value)</em>

+(4x-2) \leq 6

4x \leq 6+2

4x \leq 8

x \leq 2

<em>Second case (negative value)</em>

-(4x-2) \leq 6

Multiply by -1 both sides

(4x-2) \geq -6

(4x \geq -6+2

4x \geq -4

x \geq -1

therefore

The solution for x is the interval -----> [-1,2]

All real numbers greater than or equal to -1 and less than or equal to 2
