Please help!! What is 6(4 - y) = 5 + 3?
Archy [21]

Answer:

<h3>\boxed{ \boxed{ \bold{ \sf{2.6}}}}</h3>

Step-by-step explanation:

\sf{6(4 - y) = 5 + 3}

Distribute 6 through the parentheses

\sf{24 - 6y = 5 + 3}

Add the numbers

\sf{24 - 6y = 8}

Move constant to right hand side and change it's sign

\sf{ - 6y = 8 - 24}

Calculate

\sf{ - 6y =  - 16}

Divide both sides of the equation by -6

\sf{ \frac{ - 6y}{ - 6}  =  \frac{ - 16}{ - 6} }

Calculate

\sf{y = 2.6}

Hope I helped!

Best regards!!

solve this word problem leading to quadratic equation: the area of a rectangle is 60cm². The length is 11cm more than the width.
morpeh [17]

Answer:

Step-by-step explanation:

let : x The length and y the width you have this system :

xy =60....(1)

x = y+10...(2)

put the value for x in (1):  (y+10)y =60

the quadratic equation is : y² +10y - 60 = 0

Δ =b² - 4ac        a = 1        b= 10      c= - 60

Δ =10² - 4(1)(-60) = 324 =18²

y 1 = (-10-18)/2 negatif...... refused

y 2 = (-10+18)/2 =4

the width is 4
