Answer:

21 songs

Step-by-step explanation:

Let's figure out how many are R&B songs first.

We know that 1/4 of the 28 total songs are R&B. Remember that in mathematics, "of" usually means to multiply, so we multiply 1/4 by 28:

1/4 * 28 = 7 songs

So, 7 songs are R&B. This means that since the rest are rap, we can subtract 7 from the total 28:

28 - 7 = 21 songs

What kind of solution is -6(x-2)=-7(x-3)

Firlakuza [10]

Answer:

-6(x-2)=-7(x-3) = False x = 9

Step-by-step explanation:

Solve for x:

-6 (x - 2) = -7 (x - 3)

Expand out terms of the left hand side:

12 - 6 x = -7 (x - 3)

Expand out terms of the right hand side:

12 - 6 x = 21 - 7 x

Add 7 x to both sides:

7 x - 6 x + 12 = (7 x - 7 x) + 21

7 x - 7 x = 0:

7 x - 6 x + 12 = 21

7 x - 6 x = x:

x + 12 = 21

Subtract 12 from both sides:

x + (12 - 12) = 21 - 12

12 - 12 = 0:

x = 21 - 12

21 - 12 = 9:

Answer: x = 9

What is the rate of change between (-8,- 8) and (0,8)

iren [92.7K]

${ \qquad\qquad\huge\underline{{\sf Answer}}}$

We need to find thr rate of change (slope) of the line joining these two points ~

$\qquad \sf \dashrightarrow \: m = \dfrac{rise}{run}$

$\qquad \sf \dashrightarrow \: m = \cfrac{8 - ( - 8)}{0 - ( - 8)}$

$\qquad \sf \dashrightarrow \: m = \cfrac{8 + 8}{0 + 8}$

$\qquad \sf \dashrightarrow \: m = \cfrac{16}{8}$

$\qquad \sf \dashrightarrow \: m = 2$

Slope of the line (m) joining the two points is 2 ~

A rectangular garden has an area of 360 square feet. the length of the garden is 9 feet longer than the width. find the dimensio

rosijanka [135]

$\huge\underline{\frak{ \: \: \: \: \: \: Solution : \: \: \: \: \: \: }} \\ \\$

$\frak {\pink{Let}}\begin{cases} \sf{\red{Breadth \: be \: x}}\\ \sf{\orange{The \: Length = x + 9}}\end{cases} \\$

$\bigstar \: \underline{\textsf{According to the given Question :} }\\ \\$

$:\implies \sf Area = Length \times Breadth \\ \\ \\$

$:\implies \sf 360=(x + 9 ) x \\ \\ \\$

$:\implies \sf 360= {x}^{2} + 9x \\ \\ \\$

$:\implies \sf {x}^{2} + 9x - 360 = 0\\ \\ \\$

$:\implies \sf {x}^{2} + 24x - 15x - 360 = 0\\ \\ \\$

$:\implies \sf x(x + 24) - 15(x + 24) = 0\\ \\ \\$

$:\implies \sf (x + 24) \: (x - 15) = 0\\ \\ \\$

$:\implies \underline{ \boxed{ \sf x = - 24 \: or \: x = 15}}\\ \\ \\$

$\therefore\:\underline{\textsf{Ignoring the negative value, the Breadth of rectangular garden is \textbf{15 ft}}}. \\ \\ \\$

$\bigstar \: \underline{\textsf{Dimensions of rectangular garden :}} \\ \\$

$\bullet\:\:\textsf{The Breadth of rectangular garden = x = \textbf{15 ft.}} \\ \\$

$\bullet\:\:\textsf{The Length of rectangular garden = x + 9 = 15 + 9 = \textbf{24 ft.}} \\ \\$
