The expression 2.5a+2b gives the cost (in dollars) for a DVDs and b CDs at a moving sale. a. The cost for 1 DVD is $ and the cos
Mekhanik [1.2K]

Answer/Step-by-step Explanation:

Given:

a = no. of DVDs

b = no. of CDs

Total cost ($) for DVDs and CDs = 2.5a + 2b

a. The cost for 1 DVD = 2.5(a) = 2.5(1) = $2.5

The cost for 1 CD = 2(b) = 2(1) = $2

b. Total cost for 4 DVDs and 4 CDs:

Substitute a = 4, and b = 4 into the equation.

2.5(4) + 2(4)

10 + 8 = 18

Total cost for 4 DVDs and 4 CDs = $18

c. To find out if $20 would be enough to buy 6 DVDs and 3 CDs, substitute a = 6, and b = 3 into the equation. Solve for the total cost to see if it equals $20 or is less than $20. If it's greater than $20, then it won't be enough.

2.5(6) + 2(3)

15 + 6 = 21

6 DVDs and 3 CDs cost more than $20, therefore, $20 is not enough.

hawnda incorrectly found the distance between -26 and 25 by following these steps: Step 1: |25 – (-26)| Step 2: |25 – 26| Step 3
tekilochka [14]

Answer:

Step 2

Step-by-step explanation:

Step 2 is not correct. It should be abs(25 - - 26) = abs(25 + 26) = 51

Given that Step 2 is accepted (as - 1) then three is OK and and so is 4. But technically they are incorrect as well. I think you are likely to say that step 2 is the problem.

Sla square field has an area of 12,382m², calculate it's side length. show your work​
shepuryov [24]

Answer:

side = 111.274........

Explanation:

area of square = side × side

means we're finding area by finding square of side.

now, we're finding side. so, we'll do the opposite of square, which means square root.

side  =  \sqrt{area}

so,

side  =  \sqrt{12382}

side = 111.274........

Bob has 77 strawberries and blueberries. He wants to divide them into 2 groups so that for every 4 strawberries there are 7 blue
Serjik [45]

Answer:

44 strawberries to 77 blueberries

Step-by-step explanation:

You must change the ration to 4:7 4 strawberries to 7 blueberries.

Then divide from the total to see how many you can have.

I am guessing that you have 77 of each. so that means you can have 44 strawberries to 77 blueberries.

At this point, you've used all your fruit! Time to go get moreE

Hope this helps!
