Mathematics
1 answer:
Lisa [10]3 years ago
3 0

Answer:

1060 grams

Step-by-step explanation:

let the weight of the orange be x, then

pineapple weighs 7x, and also x + 870

equating the 2 expressions for the weight of the pineapple

7x = x + 870 ( subtract x from both sides )

6x = 870 ( divide both sides by 6 )

x = 145

The orange weighs 145 grams and the pineapple 145 + 870 = 1015 grams

Total weight of both = 145 + 1015 = 1060 grams

7(1 - y) = -3(y-2)<br> What is the answer
Fynjy0 [20]

Answer:

\huge y =  \frac{1}{4}

Step-by-step explanation:

7(1 - y) = -3(y-2)

<u>Expand the terms in the bracket</u>

That's

7 - 7y =  - 3y + 6

<u>Add 3y to both sides of the equation</u>

7 - 7y + 3y = 3y - 3y + 6 \\ 7 - 4y = 6

Subtract 7 from both sides by the equation

7 - 7  - 4y = 6 - 7 \\  - 4y =  - 1

<u>Divide both sides by - 4</u>

\frac{ - 4y}{ - 4}  =  \frac{ - 1}{ - 4}  \\

We have the final answer as

y =  \frac{1}{4}  \\

Hope this helps you

The total cost, y, for Leah and x friends to go to an amusement park can be modeled by a
Katarina [22]

Answer:

Range of the function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}

Step-by-step explanation:

Given that:

Seating capacity of the car = 6

Entrance fee per person = $45.25

Parking fee per car = $10

Leah is accompanied by x friends.

So, the total cost can be modeled as the following linear function:

y=45.25x+10

Now, the value of x i.e. number of friends going with Leah can be any of the following:

0, 1, 2, 3, 4 or 5 (because maximum capacity of the car is 6).

Leah is also going.

So, total number of people can be 1, 2, 3, 4, 5 or 6.

Therefore, the table of x, y can be:

\begin{center}\begin{tabular}{ c c}x & y \\ 1 & 55.25  \\  2 & 100.50  \\   3 & 145.75  \\ 4 & 191  \\ 5 & 236.5   \\ 6 & 281.50   \\\end{tabular}\end{center}

Here, the value of y is nothing but the range of the function.

Therefore, the range of the linear function is:

{55.25, 100.50, 145.75, 191.00, 236.25, 281.50}
