How to subtract mixed fractions with same denominators.
Answer:Rewrite the problem in vertical form.
Compare the two fractions.
If the top fraction is larger than the bottom fraction, go to Step 3.
If not, in the top mixed number, take one whole and add it to the fraction part, making a mixed number with an improper fraction.
Subtract the fractions.
Subtract the whole numbers.
Simplify, if possible.

Answer:
C: 544
Step-by-step explanation:
4hr x 2 = 8hrs this means the time is just doubled so to solve the equation we do the following
272 x 2 = 544
or
272 + 272 = 544
If f(1) = 7 and f(n) = -3f(n − 1) then find the value of f(6).
Answer:
-1701
Step-by-step explanation:
The recursion relation tells you each term of the sequence is -3 times the previous term. Then the first 6 terms are ...
7, -21, 63, -189, 567, -1701
The value of f(6) is -1701.
_____
Additional comment
The explicit formula for a geometric sequence with first term 7 and common ratio -3 is ...
f(n) = 7×(-3)^(n-1)
Then f(6) is ...
f(6) = 7×(-3)^5 = 7×(-243) = -1701
anna is on a road trip. she uses 3/4 of a tank of gas every 9/2 hours. How many tanks of gas will anna use after 12 hours?
Answer:
Step-by-step explanation:
This is a proportional question. If you learn how to keep things together, they are not only easy to do, they are mechanical: they are all done exactly the same way.
tanks of gas different tanks of gas
========== = ================
hours different hours.
initial tank of gas = 3/4 tank
initial hours = 9/2 = 4.5 hours
final tanks of gas = X
final time = 12 hours.
Solution
3/4 x
==== = ==============
4.5 12
Cross multiply
4.5x = 12*3/4 Combine the right
4.5x = 36/4 Simplify
4.5x = 9 Divide both sides by 4.5
x = 9/4.5
x = 2
So she will need 2 tankfuls.

Find the slope of the line that contains (3,-2) and (4,3).
Answer:
m = 5
Step-by-step explanation:
Recall that "slope" = rise/run.
Moving from the first point to the second, we see a 'run' of 1 and a 'rise' of 5. Thus, the slope of the line containing these two points is
m = rise/run = 5/1, or m = 5

Step-by-step explanation:
area of trapezoid = 1/2 × (a+b) h
where a = long base
b = short base
h = height
given that, a = 8, b = 5, a of trapezoid = 104:
area of trapezoid = 1/2 × ( 8+5) h
104 = 13/2 h
104 * 2 = 13 h
13 h = 208
h = 208 / 13
h = 16.0 ft.
hope this helps you!

Which of the following statements shows the distributive property?
5 + (4 – 2) = 9 + 3
5 + (4 – 2) = 20 – 10
5(4 – 2) = 20 – 10
5(4 – 2) = 9 – 7
Given that u =< 2,12 >, and z =< -7,5 >
If w = u + z, what is the value of || w ||? (answer should be accurate to 3 decimal places
Using the dot product:
For any vector x, we have
||x|| = √(x • x)
This means that
||w|| = √(w • w)
… = √((u + z) • (u + z))
… = √((u • u) + (u • z) + (z • u) + (z • z))
… = √(||u||² + 2 (u • z) + ||z||²)
We have
u = ⟨2, 12⟩ ⇒ ||u|| = √(2² + 12²) = 2√37
z = ⟨-7, 5⟩ ⇒ ||z|| = √((-7)² + 5²) = √74
u • z = ⟨2, 12⟩ • ⟨-7, 5⟩ = -14 + 60 = 46
and so
||w|| = √((2√37)² + 2•46 + (√74)²)
… = √(4•37 + 2•46 + 74)
… = √314 ≈ 17.720
Alternatively, without mentioning the dot product,
w = u + z = ⟨2, 12⟩ + ⟨-7, 5⟩ = ⟨-5, 17⟩
and so
||w|| = √((-5)² + 17²) = √314 ≈ 17.720

How do you find the sum of the exterior angle measures of any convex polygon?
If the polygon is regular, how do you find the measure of each exterior angle in the polygon?
Answer:
If a polygon is convex, then the sum of the measures of the exterior angles, one at each vertex, is 360° .
Consider the sum of the measures of the exterior angles for an n -gon.
N=180n−180(n−2)
Distribute 180 .
N=180n−180n+360 =360.
Step-by-step explanation:
The border around a picture has the same width all the way around. The perimeter of the picture is 123 cm and the perimeter of the outside of the picture frame is 191 cm. Find an equation that can be used to find to find the width of the border around the picture?
Answer:
2x +2y= 123, or
8a +2x +2y= 191
Step-by-step explanation:
Perimeter of rectangle= 2(length) +2(width)
Let the length and the width of the picture be x and y respectively.
Perimeter of the picture= 2x +2y
2x +2y= 123 -----(1)
Let the width of the border be a.
Length of picture frame= a +x +a= 2a +x
Width of the picture frame= a +y +a= 2a +y
Outer perimeter of the frame= 191
2(2a +x) +2(2a +y)= 191
Expand:
4a +2x +4a +2y= 191
8a +2x +2y= 191 -----(2)
Substitute (1) into (2):
8a +123= 191
8a= 191 -123
8a= 68
a= 68 ÷8
a= 8.5 cm
Thus the width of the border is 8.5 cm.

A businessman bought a personal computer for $10,768. Calculate the selling price of the personal computer if he made a profit of 12 percentage
Answer:
$12,060
Step-by-step explanation:
LET selling price be rep by x
since he made a profit of 12%, we then add to 100%
100% + 12% = 112%.
to find the selling price, we multiply cost price by 112%
112% x $10768 =
112 / 100 x $10,768
= 1.12 x $10,768 = 12,060
selling price = $12,060.
