Answer:

$-3.8-0.5x$

Step-by-step explanation:

A scuba diver is 3.8 meters below the surface of the water.

So, Depth of scuba driver is - 3.8 m

He is descending at a rate of 0.5 meters per minute.

So, Rate = -0.5 m . min

So,Distance traveled in x minutes = -0.05 x

So, The depth after x minutes = -3.8-0.5x

So, an algebraic expression to describe the depth of the scuba diver after any number of minutes is -3.8-0.5x

The variable x represents the no. of minutes .

OF Bisects EOG. M EOF = y+ 30 and M FOG = 3y - 50. Solve for y

Nataly_w [17]

Since it says that OF bisects EOG, it means that the angles on either side have the same measure (i.e. EOF = FOG).

We can use this to solve by setting the expressions equal to each other and solving for y.

y+30=3y-50
2y=80
y=40

Oliver makes blueberry jam every year .The number of pints of jam he makes this year can be represented by the expression 4p-9,w

tia_tia [17]

Answer:

23 pints.

Step-by-step explanation:

We have been given an expression $4p-9$ , where p is the number of pints of jam Oliver made last year. Our given expression represents the number of pints of jam Oliver makes this year.

We are also told that Oliver made 8 pints of jam last year. To find the number of pints of jam made by Oliver this year, we will substitute p=8 in our given expression.

$\text{Pints of jam made by Oliver this year}=4\times 8-9$
