if TU=6, UV=4x, and TV=7x , what is TV?
Answers
Answer:
14
Step-by-step explanation:
To find TV you must add the length of TU (6) by the length of UV (4x) to find x to find the length of TV(7x).
6+4x=7x
Do inverse operations to solve for x.
6=3x
x=2
Now that we know x is 2, we must substitute 2 in for the x in the equation for TV (7x).
7 × 2 = 14
TU = 14

How can I create equivalent expressions using the distributive property?
THIS IS MY FINAL EXAM TO GO TO THE 7TH GRADE HELP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
Equivalent expressions are expressions that have the same value. Writing equivalent expressions can make them easier to work with and solve.
Sometimes when you are writing equivalent expressions, you will need to use the distributive property. Multiply a number outside of parentheses by each number inside the parentheses.
Look at the steps for 3(2+4t).
3(2+4t) Multiply 3 by each addend.
3(2)+3(4t) To multiply 3 and 4t, multiply 3 and 4. The variable stays the same. So, 3(4t)=12t.
6+12t
So, 3(2+4t) and 6+12t are equivalent expressions.

A painter has 5 1/3 gallons of paint. It takes 4 5/9 gallons for a family room. It's estimated that it will take 6 5/9 gallons to paint the living room. How much more paint does he need to buy?
someone help please
Answers
Answer: The mixed number 5 7/9
We can write the mixed number as 5 & 7/9 to better separate the whole part (5) from the fractional part (7/9)
==================================================
Explanation:
Use this formula
[tex]a \frac{b}{c} = \frac{a*c + b}{c}[/tex]
to convert from a mixed number to an improper fraction.
Here are the steps in converting 5 & 1/3
[tex]a \frac{b}{c} = \frac{a*c+b}{c}\\\\5 \frac{1}{3} = \frac{5*3+1}{3}\\\\5 \frac{1}{3} = \frac{16}{3}\\\\[/tex]
Through similar steps you should also have
[tex]4 \frac{5}{9} = \frac{41}{9}\\\\6 \frac{5}{9} = \frac{59}{9}\\\\[/tex]
---------------
Let's add the amounts needed for the family room and the living room.
[tex]\frac{41}{9}+\frac{59}{9}\\\\\frac{41+59}{9}\\\\\frac{100}{9}\\\\[/tex]
Subtract off the amount the painter already has
[tex]\frac{100}{9} - \frac{16}{3}\\\\\frac{100}{9} - \frac{3*16}{3*3}\\\\\frac{100}{9} - \frac{48}{9}\\\\\frac{100-48}{9}\\\\\frac{52}{9}\\\\[/tex]
This improper fraction is the number of gallons of paint that's missing, i.e. the amount the painter needs to buy.
Converting it to a mixed number gets us:
[tex]\frac{52}{9}=\frac{45+7}{9}\\\\\frac{52}{9}=\frac{45}{9}+\frac{7}{9}\\\\\frac{52}{9}=5+\frac{7}{9}\\\\\frac{52}{9}=5\frac{7}{9}\\\\[/tex]
Note that 52/9 leads to a quotient of 5 and a remainder of 7. The 5 and 7 match with 5 & 7/9
The painter needs to buy 5 full gallons, plus another 7/9 of a gallon. Or we can state it as him needing 5 & 7/9 gallons of paint.

What is? A
3A-10+8+A=2A+5A-11
Answers
Answer:
A = 3
Step-by-step explanation:
[tex]3a - 10 + 8 + a = 2a + 5a - 11\\[/tex]
Steps:
1) Combine like terms
[tex]4a-2 = 7a-11[/tex]
2) Either subtact 7a from 4a or 4a from 7a. ( I did 7a-4a because so i dont have a negiative in front of my variable)
[tex]-2 = 3a -11[/tex]
3) If u did it like me you add 11 to -2 and add 11 to -11 (which cancel out)
[tex]9=3a[/tex]
4) Divide 3a by 3(which is just a) and 9 divided by 3
[tex]3=a[/tex]
4) Check your answer (just plug in 3 for a and solve. You should get 10=10.)

If 19th term of an A.P. is 844 and 844th term is 19 then find the term which is equal to zero?
Answers
Let aₙ be the n-th term of the A.P.
Then for some fixed number d,
[tex]a_{844} = a_{843} + d[/tex]
[tex]a_{844} = (a_{842} + d) + d = a_{842} + 2d[/tex]
[tex]a_{844} = (a_{841} + d) + 2d = a_{841} + 3d[/tex]
and so on.
Notice how on the right side, the subscript of a and the coefficient of d always add up to 844. Follow this pattern all the way down to a₁₉ to get
[tex]a_{844} = a_{19} + 825d[/tex]
We're told that a₁₉ = 844 and a₈₄₄ = 19. Solve for d :
19 = 844 + 825d
825d = -825
d = -1
We can also write aₙ in terms of an arbitrary k-th term, aₖ, using the pattern from before:
[tex]a_n = a_k + (n - k) d[/tex]
Suppose aₖ = 0 for some value of k. Pick any known value of aₙ, replace d = -1, and solve for k :
a₈₄₄ = 0 + (844 - k) • (-1)
19 = k - 844
k = 863
So, a₈₆₃ = 0.

A man walking his dog along a Straight road spots a friend a mile away. They wave at one another and the dog sprints to greet her. As soon as the dog arrives it turns around and runs straight back to its master. Then turns around again and runs back to the girl, who is, of course, nearer now. The dog continues running backs and forth until the two meet. Given that each person walks at a steady 3 mph, and the dog runs a steady 9 mph, what is the total distance the dog runs?
Answers
The distance the dog runs is given by the time it takes the man and the
girl to meet multiplied by the speed of the dog.
Correct response:
The total distance the dog runs is 1.5 milesHow to find the distance ran by the dogGiven parameters;
Initial distance of the friend away = 1 mile
Speed of the man = 3 mph
Speed of the girl = 3 mph
Speed of the dug = 9 mph
Required:

Solution:
[tex]Time = \mathbf{\dfrac{Distance}{Speed}}[/tex]
The time it takes the man and the girl to meet, t, is given as follows;

Type the missing number in this sequence: 1, 5, 5, 25, 125, .....

2. However, this differs from the Fibonacci sequence because instead of adding, we're multiplying. 1 x 5 = 5, 5 x 5 = 25, 5 x 25 = 125. Given this sequence, we have to multiply 25 by 125 next, and the product of that expression is 3,125!
