Answer:

$\huge\boxed{4t-3}$

Step-by-step explanation:

$\dfrac{1}{5}(20t-15)\qquad|\text{use the distributive property}\ a(b+c)\\\\=\left(\dfrac{1}{5}\right)(20t)-\left(\dfrac{1}{5}\right)(15)=4t-3$

Explain how modeling partial products can be used to find the products of greater numbers ?

liq [111]

You can break large numbers into a sum of a multiple(s) of 10 and the last digit of the number. For example, you can break 26 as 20+6, or 157 as 100+50+7.

Then, using the distributive property, you can turn the original multiplication into a sum of easier multiplications. For example, suppose we want to multiply 26 and 37. This is quite challenging to do in your mind, but you can break the numbers as we said above:

$26\times 37=(20+6)(30+7) = 20\times 30+20\times 7+30\times 6+6\times 7$

All these multiplications are rather easy, because they either involve multiples of 10 of single-digit numbers:

$20\times 30+20\times 7+30\times 6+6\times 7 = 600+140+180+42=962$

Roblem #7

gtnhenbr [62]

Answer:

no solution.

Step-by-step explanation:

1) in order to explain, the given system should be resolved:
$\left \{ {{2y=6x+4} \atop {y=3x-4}} \right. \ < = > \ \left \{ {{y=3x+2} \atop {y=3x-4}} \right.$

2) the both equations have the same slope (it is 3), it means the given lines are parallel, then no solution.

the radius of a cylindrical construction pipe is 2.5 ft. if the pipe is 21 ft long, what is its volume? use the value 3.14 for p

pishuonlain [190]

Answer: The volume of the pipe is 412 cubic feet

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Volume of a cylinder = π x radius² x height (Length in this case)

Replacing with the values given:

V = 3.14 (2.5)² 21 = 3.4 (6.25) 21 = 412.12 = 412 cubic feet (rounded)

In conclusion, the volume of the pipe is 412 cubic feet

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

Answer:

7 X / 2 y

Step-by-step explanation:

let Mel equals to X and female equals to y

therefore ×=y

therefore to make the count proper we have to multiply the male by 7

so 7 x = 2y and the fraction becomes 7 X / 2 y

hope this helps
