Answer:

a = -0.5

Step-by-step explanation:

\rm Solve  \: for  \: a: \\  \rm \longrightarrow - \dfrac{1}{4}a  - 4 =  \dfrac{7}{4}a  - 3 \\   \\  \rm Put \:  each  \: term \:  in  \: - \dfrac{1}{4}a  - 4  \:  over \:  the \\ \rm  common  \: denominator  \: 4: \\ \rm - \dfrac{a}{4}  - 4  = - \dfrac{a}{4}  -  \dfrac{16}{4} :  \\ \rm \longrightarrow  - \dfrac{a}{4}  -  \dfrac{16}{4}  = \dfrac{7}{4}a  - 3 \\  \\  \rm  - \dfrac{a}{4}  -  \dfrac{16}{4}  = \dfrac{ - a - 16}{4}  : \\  \rm \longrightarrow  \dfrac{ - a - 16}{4} = \dfrac{7}{4}a  - 3  \\  \\ \rm Put  \: each  \: term \:  in \: \dfrac{7}{4}a  - 3   \:  over  \: the  \\ \rm common \:  denominator \:  4: \\  \rm  \dfrac{7a}{4}  - 3  =  \dfrac{7a}{4} -  \dfrac{12}{4} : \\   \rm \longrightarrow  \dfrac{ - a - 16}{4} = \dfrac{7a}{4}  -  \dfrac{12}{4}  \\  \\  \rm  \dfrac{7a}{4} -  \dfrac{12}{4}  =  \frac{7a - 12}{4} : \\  \rm \longrightarrow  \dfrac{ - a - 16}{4} = \dfrac{7a - 12}{4}   \\  \\  \rm Multiply  \: both  \: sides  \: by \:  4:  \\ \rm \longrightarrow  \dfrac{ - a - 16}{ \cancel{4}}  \times  \cancel{4}= \dfrac{7a - 12}{ \cancel{4}}  \times  \cancel{4} \\  \\  \rm \longrightarrow -a - 16 = 7 a - 12 \\  \\  \rm Subtract \:  7 a  \: from \:  both  \: sides: \\  \rm \longrightarrow (-a - 7 a) - 16 = (7 a - 7 a) - 12 \\  \\  \rm -a - 7 a = -8 a: \\  \rm \longrightarrow -8 a - 16 = (7 a - 7 a) - 12 \\  \\  \rm 7 a - 7 a = 0: \\  \rm \longrightarrow -8 a - 16 = -12 \\  \\  \rm Add \:  16 \:  to \:  both  \: sides: \\  \rm \longrightarrow (16 - 16) - 8 a = 16 - 12 \\  \\  \rm 16 - 16 = 0: \\  \rm \longrightarrow -8 a = 16 - 12 \\  \\  \rm 16 - 12 = 4: \\  \rm \longrightarrow -8 a = 4 \\  \\  \rm Divide \:  both \:  sides \:  of \:  -8 a = 4  \: by \:  -8: \\  \rm \longrightarrow  \dfrac{ - 8a}{ - 8}  =  \dfrac{4}{ - 8}  \\  \\  \rm  \dfrac{ - 8}{ - 8}  = 1: \\  \rm \longrightarrow a =   - \dfrac{4}{  8}  \\  \\  \rm   - \dfrac{4}{  8}  =  -  \dfrac{1}{2}  :  \\   \rm \longrightarrow a =  -  \dfrac{1}{2}  \\  \\  \rm \longrightarrow a =  - 0.5

It would be d because youing the point slope equation which is (y - y1) = m (x- x1) when distributing the point and the slope into the equation asl well as sinplifying youll get D. Y1 is the value of the y in the ordered pair and x1 is the x value of the ordered pair.

How many different 11-letter arrangements can be made using the letters in the word Firecracker?
zhenek [66]

Answer:

Total number of arrangements = 1,663,200

Step-by-step explanation:

Given:

11 - letter

FIRECRACKER

F = 1

I = 1

R = 3

E = 2

C = 2

A =1

K = 1

Find:

Total number of arrangements = ?

Computation:

Note: Repeated letter will be avoid.

Number\ of\  arrangements = \frac{!11}{!3 \times !2 \times !2}\\\\Number\ of\  arrangements = \frac{!11}{!3 \times !2 \times !2} \\\\Number\ of\  arrangements = \frac{11 \times 10 \times 9 \times 8 \times 7 \times 6 \times 5 \times 4 \times 3}{3 \times 2 \times 2 } \\\\Number\ of\  arrangements = 1,663,200

Total number of arrangements = 1,663,200

Pls help ! i dont understand how to solve this
Mazyrski [523]

Answer:

answer is 4

Step-by-step explanation:

we need to find the width of the larger rectangle: 100/20=5

and then find the scale between them

20/4=5

and use the width to divide by that, and you will get the width for the smaller shape, which is 5/5=1

1*4=4
