Answer:
Step-by-step explanation:
the way you do it is by checking the letter in every term and seeing which instance has the lowest of that letter (for now pretend the regular numbers, in this case 6 24 and 12, aren't there). Once you do that you'll see that the last term has each variable (letter) to the power of one, so that will be the common factor for the letters. Next, look at the real numbers, and you see that the lowest number each can be divided by is 6. so you have 6abc. I'm tired and I think I explained it in a confusing way, so if you still have questions search up "how to find the greatest common factor in polynomials"
Well first you have to make variables for each number.
1st - x
2nd - y
3rd - z
first sentence says twice first number so 2x. is means equals so =. eleven more than sum of the other two numbers. sum of other two numbers is (y + z) and eleven more than that is (y + z) + 11. So so this sentence says:
2x = (y + z) + 11
second sentence says sum of twice the first and three times third. twice first is 2x and three times third is 3z. their sum would be (2x + 3z). It it says is one more than second number. So = (y + 1). So so this means:
(2x + 3z) = (y + 1)
third sentence says second number (y) is is equal to sum of first and third (x + z). so;
y = (x + z)
now for the work.
We we can easily solve for a by subtracting the first 2 equations. the way to subtract 2 equations is by subtracting one left side of equal sign from the other equations left side and then doing the same with the right side.
So we will subtract the 1st and second equations we made.
So so left sides would be
2x - (2x + 3z)
2x - 2x - 3z
-3z
right side would be:
y + z + 11 - (y + 1)
y + z + 11 - y - 1
z + 10
now put the sides with an equal sign
-3z = z + 10
-4z = 10
z = -2.5
now we can plug in z into the equations and subtract second and third equations. But but we will subtract opposite sides. So so left minus right and right mi is left after we plug in z:
(2x + 3 (-2.5)) - (x + (-2.5))
2x - 7.5 - x + 2.5
x - 5
other one would be
(y + 1) - y
1
So so put an equal sign and get:
x - 5 = 1
x = 6
now plug x and x into 3rd equation
y = x + z
y = 6 + (-2.5)
y = 3.5
now we have values. You can check answer by plugging values into other 2 equations
Answer:
t=15/4 or 3.75
Step-by-step explanation:
t x 3/15 =3/4
t x 3/15 ÷3/15 = 3/4 ÷3/15 (Divide each side by 3/15)
t= 3/4 x 15/3
t=15/4 or 3.75
It’s 2 and easy thank you have nice hope u have fun
Answer: 5h represents the number of hours Rob actually spent on the project.
Step-by-step explanation:
Let Rob planned that he will spend x hours in his project.
According to the question,
He spent 25% more time on his project than he planned.
That is, his actual time = x + 25% of x = 125% of x
Again according to the question,
He spent an extra h hours on his project.
That is, 25% of x = h
x = 4h
Thus, his actual time = 125% of x = 125% of 4h = 
= 5h
Which is the required expression.
