why do terms have to be like terms?
Answer:
Like terms are terms that contain the same variables raised to the same power. Only the numerical coefficients are different. In an expression, only like terms can be combined. We combine like terms to shorten and simplify algebraic expressions, so we can work with them more easily.
.A bucket is filled with 1 3/4 gallons of water. The bucket has a small hole and 1/4 gallon leaks out every hour. How many hours will it take for the bucket to be completely empty? What must you do to the mixed number in order to solve this problem?
Given :
A bucket is filled with 1 3/4 gallons of water.
The bucket has a small hole and 1/4 gallon leaks out every hour.
To Find :
How many hours will it take for the bucket to be completely empty.
Solution :
We know , mixed fraction of form a p/q is given by :
[tex]a\ p/q = \dfrac{(a\times q)+p}{q}[/tex]
So, 1 3/4 = 7/4 .
Let, after t hours bucket is empty.
[tex]\dfrac{7}{4}-\dfrac{1}{4}t = 0\\\\t = 7\ hour[/tex]
Therefore, it takes 7 hours for the bucket to be completely empty.
Hence, this is the required solution.

Which series of transformations will move the triangle in quadrant 1 onto the similar triangle in quadrant three?
Answer:
Its D if you think about it
Step-by-step explanation:in your mind move the triangle on the top right down 6 units and then turn your triangle 90 degrees counter clockwise (quick maths)
The only transformation that will move the triangle in quadrant 1 onto the similar triangle in quadrant three is;
Option D; translation 6 units down and rotation 90° counterclockwise
The y-coordinate of the right angle vertex of the triangle in quadrant 1 is y = -2. Meanwhile the y-coordinate of the same right angle point of the triangle in quadrant 3 is y = -4.
Thus, for the triangle in quadrant 1 to be on the same level with that in quadrant 3, we need to translate the triangle in quadrant 1 downwards by 6 units.
Now, since we want to map this newly translated triangle to the one in quadrant 3 and as such we need to rotate it 90° counterclockwise

A delivery truck drives three routes in one day. The first route is 1223 miles long, the second route is 1034 miles long, and the third route is 1512 miles long. What is the total number of miles the delivery truck drives? Enter your answer as a mixed number in simplest form by filling in the boxes. $$ miles
Answer:
[tex]Total = 38\frac{11}{12}\ miles[/tex]
Step-by-step explanation:
Given
[tex]First\ Route = 12\frac{2}{3}\ miles[/tex]
[tex]Second\ Route = 10\frac{3}{4}\ miles[/tex]
[tex]Third\ Route = 15\frac{1}{2}\ miles[/tex]
Required
Determine the total miles
[tex]Total = First\ Route + Second\ Route + Third\ Route[/tex]
[tex]Total = 12\frac{2}{3} + 10\frac{3}{4} + 15\frac{1}{2}[/tex]
Convert to improper fractions
[tex]Total = \frac{38}{3} + \frac{43}{4} + \frac{31}{2}[/tex]
Take LCM
[tex]Total = \frac{152 + 129 + 186}{12}[/tex]

Answer:
2 (3 y - 4) <- Complete answer, but since you only have those choices it's
6 y - 8
Step-by-step explanation:
Simplify the following:
8 y - 2 (y + 4)
Hint: | Distribute -2 over y + 4.
-2 (y + 4) = -2 y - 8:
8 y + -2 y - 8
Hint: | Group like terms in 8 y - 2 y - 8.
Grouping like terms, 8 y - 2 y - 8 = (8 y - 2 y) - 8:
(8 y - 2 y) - 8
Hint: | Combine like terms in 8 y - 2 y.
8 y - 2 y = 6 y:
6 y - 8
Hint: | Factor out the greatest common divisor of the coefficients of 6 y - 8.
Factor 2 out of 6 y - 8:

Plz HELP with a and b I WILL MARK AS A BRAINLIEST IF YOU CAN HELP ME WITH BOTH A AND B PLZZ
Answer:
a) x = 60
b) b = 110
Step-by-step explanation:
A)
2x and 120 are vertical angles.
vertical angles are equivalent.
2x = 120
divide both sides of the equation by 2
2x/2 = 120/2
x = 120/2
x = 60
B)
b + 20 and 130 are on the same side of the line
(I forgot what the math term is, but they're also equal)
b + 20 = 130
subtract 20 from both sides of the equation
b + 20 - 20 = 130 - 20
b = 130 - 20
b = 110
The output of a function is 5 more than 2 times the input. Find the input when the output is 17.
Answer:
The input when the output is 17 is x=6.
Step-by-step explanation:
Functions
Assume the input is called x and the output is the function f(x). Two times the input is 2x. 5 more than that is 2x+5.
Knowing the output of the function is 5 more than 2 times the input, we can write the function as:
f(x)=2x+5
Now find the input x when the output is 17:
17=2x+5
Swap sides of the equation:
2x+5=17
Subtract 5:
2x=17-5=12
Divide by 2:
x=12/6=6
The input when the output is 17 is x=6.

what is 11x11 ????????????????????
Answer:
121
Step-by-step explanation:
11 x 11
this is what goes on in my head you don't have to this but this is what i do
10 x 10 = 100
10 x 1 = 10
1 x 10 = 10
1 x 1 = 1
100 + 10 + 10 + 1 = 121
The product of the numbers 11 with 11 is 121.
Given are the numbers 11 and 11.
We have to find the product of these numbers.
This can be found in various ways.
We can study the perfect squares from 1 to 20 to know it fast.
Else you can use normal multiplication.
Or another method is,
Split both 11 as 10 and 1 and then find the product with each.
10 × 10 = 100
Then find 10 with 1.
10 × 1 = 10
Then find 1 with 10.
1 × 10 = 10
Then find 1 with 1.
1 × 1 = 1
Total is 100 + 10 + 10 + 1 = 121
Hence the number is 121.
