For membership to an athletic club, it costs $110 to join and $25 per month of membership. Write an equation to show the situati
lord [1]

Answer:

110 + 25x = Total Cost (or any type of variable needed, like a,b,c, etc.)

Step-by-step explanation:

Since the monthly fee occurs more than once, and we don't have the number of months, we put an x to represent the amount of months. The $110 is the one time additional fee for the membership, so it doesn't need a variable.

-5/4 divided by 2 3/5
Alecsey [184]

-5/4 ÷ 2 3/5

Let's turn 2 3/5 into a complete fraction so multiply bottom by two and add it to the top. Take the answer and put it over the original bottom. SO: 13/5

Now KEEP CHANGE FLIP

keep -5/4

change sign to ×

flip 13/5 to 5/13

Thus: -5/4 × 5/13

Simply, multiply

-25/52

Done, hope that helps :)

Find the area of the figure. Explain your reasoning.
Grace [21]

Answer:

Separate it into smaller figures.

Step-by-step explanation:

The figure can be separated into a triangle on the top, and 2 trapezoids on the middle and the bottom.

The area of the triangle is bh/2, which is (4 x 6)/2, which is 12.

The area of the trapezoid in the middle is .5(b1+b2)h, which is .5(6+4)3, which is 15.

The area of the trapezoid on the bottom is .5(6+5)2, which is 11.

Now, add them to get 12+11+15 which is 38.
