Donnell practiced for 7 hours while Marcus practices the piano for 4 hours.
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of hours piano played by Donnell is D while by Marcus is M.
Then,
Since Donnell practiced the piano 3 hours longer than Marcus.
D = 3 + M ⇒ D - M = 3
And,
Together, Marcus and Donnelly practiced the piano for 11 hours.
D + M = 11
By adding
2D = 14
D = 7
And,
M = 11 - 7 = 4
Hence "Donnell practiced for 7 hours while Marcus practices the piano for 4 hours".

Answer:
The three-person trip require more effort (row harder) than the two person-trip
Step-by-step explanation:
The number of persons in the boat determines the mass of the boat
The mass of the boat with three people in total is more than the mass of the boat with only two person's
Mass is a measure of inertia, which is the resistance of a body to accelerate, and therefore, to the application of a force
Therefore, on the three-person trip were three people are in the boat, the boat has more mass, and therefore more inertia and will require more effort (force) than on the two-person trip that has a lesser mass
Answer:
49 kg.
Step-by-step explanation:
We have been given that Ava's dog weighs 56 kilograms. Marty's dog weighs 7/8 as much. We are asked to find the weight of Marty's dog.
To find the weight of Marty's dog, we will multiply 56 by .
Therefore, the weight of Marty's dog is 49 kilograms.
Answer: 28
Step-by-step explanation:
To find the common denominator, you want to find the least common multiple of 4 and 7. The easiest way to do this is to multiply the denominators.
4*7=28
Therefore, the common denominator is 28.
The common denominator of the fractions 8/7 and 2/4 is 28. This is found by multiplying the original denominators together, as this resulting product can be evenly divided by both original denominators.
The question is asking for the common denominator of two fractions, 8/7 and 2/4. A common denominator is a number that both denominators can divide into evenly.
To find this, let's first look at the denominators of your two fractions. We have 7 and 4 as the denominators.
Start by multiplying these two numbers together to give 28. Indeed, both 7 and 4 can divide into 28 evenly (7*4=28, 4*7=28) so, 28 is a common denominator for these two fractions.
Therefore, the common denominator of 8/7 and 2/4 is 28.
