Answer:

option a) 30 : 19

Step-by-step explanation:

$Length = 7 \frac{1}{2} = \frac{15}{2}\\\\Width = 4\frac{3}{4} = \frac{19}{4}$

Ratio of length to width:

$\frac{15}{2} : \frac{19}{4}$

$=\frac{\frac{15}{2}}{\frac{19}{4}}\\\\=\frac{15}{2 } \times \frac{4}{19}\\\\=15\times \frac{2}{19}\\\\=\frac{30}{19}\\\\30 : 19$

Answer:

5. C. {(22, 10), (23, 10), (24, 7), (25, 5)}

6. C. x = -2

Step-by-step explanation:

A relation is not a function if a vertical line intersects a graph of it in more than one place.

5. A set of ordered pairs is not a function if any of the first-values is repeated.

In set A, (22, ) is repeated.

In set B, (23, ) is repeated.

In set D, (24, ) is repeated.

In set C, no first-value is repeated, so the relation is a function.

6. The line x=-2 is a vertical line, so a vertical line intersect it in an infinite number of places. It is NOT a function.

13= -2(x+1) + 7x solve for x

Veronika [31]

Answer:

x=3

Step-by-step explanation:

13= -2 (x+1) +7x (given)

13+-2x - 2 +7x (distributive property of multiplication over addition)

13 + 5x -2 (combine like terms)

15 = 5x (addition property of equality)

3 = x (division property of equality)
