Answer:

The inequality is 55+10x\leq 105

The greatest length of time Jeremy can rent the jet ski is 5 and Jeremy can rent maximum of 135 minutes.

Step-by-step explanation:

Given: Cost of first hour rent of jet ski is $55

          Cost of each additional 15 minutes of jet ski is $10

          Jeremy can spend no more than $105

Assuming the number of additional 15-minutes increment be "x"

Jeremy´s total spending would be first hour rental fees and additional charges for each 15-minutes of jet ski.

Lets put up an expression for total spending of Jeremy.

\$55+ \$ 10\times x

We also know that Jeremy can not spend more than $105

∴ Putting up the total spending of Jeremy in an inequality.

\$ 55+\$10x\leq \$ 105

Now solving the inequality to find the greatest number of time Jeremy can rent the jet ski,

⇒ \$ 55+\$10x\leq \$105

Subtracting both side by 55

⇒ \$ 10x\leq \$50

Dividing both side by 10

⇒x\leq \frac{50}{10}

∴ x\leq 5

Therefore, Jeremy can rent for 60\ minutes + 5\times 15\\= 60\ minutes + 75= 135\ minutes

Jeremy can rent maximum of 135 minutes.

deff fn [24]

Answer:

6 hours

Step-by-step explanation:

Suppose Madison spent x hours on her social project,

then the number of hours spent on other project will be 1/3 of x=x/3

Total hours spend on all projects will be the addition of hours spent on social project and hour spent on other project, i.e

x + x/3 = 4x/3

It si given that this is 8 hours, therefore

4x/3=8

Multiplying both sides by 3:

4x=24

Dividing across board by 4:

x= 6 hours

Rearrange w= 3(2a + b) - 4 to make a the subject
Angelina_Jolie [31]

Answer:

\boxed{a =  \frac{w}{ 6}  -  \frac{b}{2}  +  \frac{2}{3} }

Step-by-step explanation:

Solve  \: for \:  a:  \\  =  > w=3(2a+b)-4  \\  \\ w=3(2a+b)4 \: is \: equivalent \: to \: 3(2a+b)-4= w:  \\  =  > 3(2a+b) - 4=w  \\  \\ Expand \:  out \:  terms \:  of  \: the  \: left  \: hand \:  side:  \\  =  > (3 \times 2a) + (3 \times b) - 4 = w \\  =  > 6a+3b - 4=w  \\  \\ Subtract  \: 3b  - 4 \:  from  \: both \:  sides:  \\  =  >   6a + 3b - 4 - (3b - 4)=w - (3b - 4) \\   =  > 6a = w - 3b + 4 \\  \\ Divide  \: both  \: sides \:  by  \: 6: \\  =  >  \frac{ \cancel{6}a}{ \cancel{6}}  =  \frac{w - 3b + 4}{6}  \\   =  > a =  \frac{w}{6}  -  \frac{3b}{6}  +  \frac{4}{6}  \\  =  > a =  \frac{w}{ 6}  -  \frac{b}{2}  +  \frac{2}{3}
