Question 4:
2x-3
Because we don’t know how much Fernando has that would be where we fill in the variable giving you 2x then 3 dollars less will give you the -3 therefore 2x-3
Question 5:
1/2x+7
Because we don’t know Deb’s age that would be the variable and we are looking for half of Deb’s age giving you 1/2x then the 7 years more giving you the +7 hence 1/2x+7

The circumference of the flotation device above is 62.8 inches . If three flotation devices are lined up end-to-end , then what
Karo-lina-s [1.5K]

Answer: 60 in

Step-by-step explanation:

Hi, to answer this question, first we have to calculate the diameter of one flotation device:

Circumference of a circle C = (3.14) (diameter)

Replacing with the values given:

62.8 =3.14 d

Solving for d (diameter)

62.8 /3.14 =d

20in = d

Now, since the three flotation devices are identical, we simply have to multiply the diameter of one device by 3 , to obtain length of the flotation devices lined up.

20x3 =60 in

Feel free to ask for more if needed or if you did not understand something.

How do you multiply and then use distributive property?
morpeh [17]
It depends on the question given, for example

you can do distributive property will multiplying.

Example 1:

there is two ways on doing distributive property.

I can do 4(8+3)

add 8+3 since it is inside the parenthesis which equals = 11 then multiply the outside on what you added. 4x11= 44

example 2: I can also do it another way. 4(8+3) distribute the 4 by multiplying the 4 with both numbers. 4x8 and 4x3 which equals 32, and 12. add 32+12=44

so either way you will get the same answer. hope I helped.
