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

let's solve ~

\qquad \sf  \dashrightarrow \:  \cfrac{4}{y - 6} +  \cfrac{5}{y + 3}   =  \cfrac{7y - 4}{ {y}^{2}  - 3y - 18}

\qquad \sf  \dashrightarrow \:  \cfrac{4(y + 3) + 5(y - 6)}{(y - 6)(y + 3)}  =  \cfrac{7y - 4}{ {y}^{2}  - 3y - 18}

\qquad \sf  \dashrightarrow \:  \cfrac{4y + 12 + 5y - 30}{ {y}^{2}  +  3y - 6y - 18 }  =  \cfrac{7y - 4}{ {y}^{2}  - 3y - 18}

\qquad \sf  \dashrightarrow \:  \cfrac{9y  - 18}{ {y}^{2}   - 3y - 18 }  =  \cfrac{7y - 4}{ {y}^{2}  - 3y - 18}

\qquad \sf  \dashrightarrow \: 9y - 18 = 7y - 4

[ denominator is same, so numerator must have same value to be equal ]

\qquad \sf  \dashrightarrow \: 9y - 7y =   - 4 + 18

\qquad \sf  \dashrightarrow \: 2y = 14

\qquad \sf  \dashrightarrow \: y = 7

For the 6-day workweek: multiply 4.8 times 6 = 28.8 km.
For July: multiply 27 times 4.8 = 129.6 km.

Hello, I was wondering if someone would be able to help me with this problem I'm on. Thanks :)

<span><span>Price after trade discount = $14,000 - (40% trade discount)

Price after trade discount = $14,000 - ($14,000 * 0.4)

Price after trade discount = $14,000 - ($5,600)

Price after trade discount = $8,400 </span>Price after trade discount = $8,400

2/10 EOM price = $8,400 - (2% discount)

2/10 EOM price = $8,400 - ($8,400 * 0.02)

2/10 EOM price = $8,400 - ($168)

2/10 EOM price = $8,232

So Intel will pay $8,232 on August 5.
Hope this helps.

Math help please show work thanks

Problem 5

d = 29 = diameter

r = d/2 = 29/2 = 14.5 = radius

SA = surface area of sphere

SA = 4*pi*r^2

SA = 4*pi*(14.5)^2

SA = 841pi

SA = 841*3.14

SA = 2,640.74 square inches

To convert from square inches to square feet, we divide by 144. This is because 12^2 = 144.

2,640.74 square inches = (2,640.74)/144 = 18.3 sq ft

<h3>Answer: 18.3 square feet (approximate)</h3>

=====================================

Problem 6

d = 10.7 = diameter

r = d/2 = 10.7/2 = 5.35 = radius

L = 22.3 = slant height

SA = surface area of the cone

SA = pi*r^2 + pi*r*L

SA = pi*(5.35)^2 + pi*5.35*22.3

SA = 147.9275pi

SA = 147.9275*3.14

SA = 464.49235

<h3>Answer:  464.49235 square cm (approximate)</h3>
