An easy way to do this is instead of dividing, multiply the denominator by 5. You get 15. You can say Im just making a coincidence, but try it yourself!
(1/3)/5 is basically multiplication. You may have heard the saying, "division with fractions is multiplication". Thats true. Turn 5 into 5/1 and multiply. 5/1x1/3.
you get 1/15. Hope it helps
Also you have to flip 5/1 to 1/5 and then multiply hehe. thats how you get 1/15

Triangle TAG is graphed as shown
Which of the following transformations will move triangleTAG so that point G is at the origin?
Answer:
The transformation is (x,y) to (x-2,y-6)
Step-by-step explanation:
First of all, we note the coordinates of the point G
The coordinates of the point G is (2,6)
To bring this to the origin, we are looking at bringing it to the point (0,0)
To do this, we subtract 2 from the x-value and 6 from the y value
So what we have is that;
(x-2) and (y-6)
(x-2, y-6)
The length of each side of an equilateral triangle is 74 mm, correct to the nearest millimetre.
Calculate the smallest possible perimeter of the triangle.
Answer:
222mm
Step-by-step explanation:
The perimeter of a triangle is the sum of all of the sides. This triangle is equilateral, which means that all sides are equal and in this case, each side is 74mm. So to find the perimeter of this triangle add each, 74+74+74, which equals 222. Therefore, the answer must be 222mm.
Answer:
the answer is 222 mm.

Answer:
2. x=5
y=10
3. x=21
y=4
Step-by-step explanation:
2. 13y=20x+3y 10y=20x
8x+y=180-13y 14y=180-8x
y=2x plugging that into 14y=180-8x 28x=180-8x 36x=180 x=5
plug x into 10y=20x 10y=100 y=10
3. 3(x+y)=(4x-9) 3x+3y=4x-9 x=3y+9
5x=180-4x+9 9x=189 x=21
plug 21 into x=3y+9 21=3y+9 12=3y 4=y

Abigail drew a scale drawing of the oldest house in her town. The actual house is 64 feet long. Abigail's scale drawing is 8 inches long. What scale did Abigail use to draw the house? 8 inches equal 1 foot 8 inches equal 18 foot 1 inch equals 18 foot 1 inch equals 8 feet
Answer:
1 inch equals 8 feet
Step-by-step explanation:
Given that;
Abigail drew a scale drawing of the oldest house in her town.
The actual length of the house = 64 feet long
Abigail scale drawing = 8 inches long
The scale he used in drawing the house is determined by choosing a perfect scale:
i.e
If 8 inches is used to draw an actual length of a house which is 64 feet long,
Then 1 inch should be able to draw (64 feet * 1 inch)/ 8 inches
So, 1 inch should be able to draw 8 feet long
The scale used to draw the given house is required.
The scale used to draw the diagram is 1 inch equals 8 feet.
Scale diagramsActual length of the house = 64 feet
Scale drawing length = 8 inches
So,
[tex]64\ \text{feet}=8\ \text{inches}[/tex]
Now, the inches to feet is required.
So, we divide both sides with 8.
[tex]\dfrac{64}{8}\ \text{feet}=\dfrac{8}{8}\ \text{inches}\\\Rightarrow 8\ \text{feet}=1\ \text{inch}[/tex]
So, 1 inch in the diagram is 8 feet of actual length.

Given f of x equals 6 1 minus x , what is the value of f of negative 6 ?
Answer:
answer will be 67
Step-by-step explanation:
f(x) = 61 - x
x = -6
hence we substitute the value of x in f(x)
f(-6) = 61 - (-6)
= 61 + 6
= 67
The value of the function f(x) = 6(1 - x) at x = -6 will be given 42.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The function is given below.
f(x) = 6(1 - x)
The value of the function at x = -6 will be given as,
f(-6) = 6[1 - (-6)]
Simplify the equation, then we have
f(-6) = 6[1 - (-6)]
f(-6) = 6(1 + 6)
f(-6) = 6 × 7
f(-6) = 42
The value of the function f(x) = 6(1 - x) at x = -6 will be given 42.

determine whether g(x)=x2-5x+2 has a minimum of maximum
Answer:
g(x) has a minimum
Step-by-step explanation:
Given a quadratic in standard form
g(x) = ax² + bx + c ( a ≠ 0 )
• If a > 0 then vertex is a minimum
• If a < 0 then vertex is a maximum
Given
g(x) = x² - 5x + 2 ← in standard form
with a > 0 , thus

Anna is trying to figure out how much her 10-mile taxi ride is going to cost. It costs $5 to be picked up by the taxi, and each mile costs an extra $2. Which equation should Anna use to calculate her cost?
y= 2x+5
y= 5x+2
y= x^2+5x+10
y=(2)^x
Answer:
y=2x+5
because y is the final cost, x is the amount of miles times 2 since each mile costs $2, and an addition $5 for the taxi-pickup
