4.2 is also equal to 42/10 which is equal to 21/5. In order to find how many trips you will be dividing fractions (21/5) / (3/5). Although this may seems difficult, because the denominators are the same, it simplifies to 21/3 which is equal to 7 (A)

Is 1/8 grader than or less than 2/5
Oduvanchick [21]

\large\text{Hey there!}

\mathsf{Is\ \dfrac{1}{8}\ greater\ than\ or\ less\ than\ \dfrac{2}{5}\ ?}

\large\text{Personally, if you convert your fractions into decimals it can be easier to}\\\large\text{to answer your question. Or you could even match it with the LCD}\\\large\text{if it is easier for you!}

\mathsf{\dfrac{1}{8}=0.125} \\\\\mathsf{\dfrac{2}{5}=0.40}

\large\text{The\ LCD (Lowest Common Denominator) is 40}

\mathsf{Match\ your\ fractions\ with\ your\ LCD}\\\\\boxed{\mathsf{\dfrac{1}{8}}}\boxed{\mathsf{\dfrac{2}{5}}}\\\boxed{\mathsf{\dfrac{5}{40}}}\boxed{\mathsf{\dfrac{16}{40}}}

\large\text{We compared }\mathsf{\dfrac{1}{8}\ \&\  \dfrac{5}{40}.}\large\text{ We also compared }\mathsf{\dfrac{2}{5} \  \& \ \dfrac{16}{40}}

\mathsf{Both\ \dfrac{2}{5} \& \ \dfrac{16}{40}\ are\ LESS/ SMALLER\ than\ \dfrac{1}{8} \ & \ \dfrac{5}{40}}

\boxed{\boxed{\large\text{Thus your answer is: \boxed{\mathsf{\dfrac{1}{8} \ is\ GREATER\ than\  \dfrac{2}{5}}}}}}}\huge\checkmark

The length of a square is increased by 2 inches. The perimeter of the original square is ten inches more than the length of one
Lapatulllka [165]
Let x be the length of one side of the smaller square
Let y be the length of one side of the larger square
4x would be the perimeter of the smaller square, as it has 4 sides
Therefore 4x = y + 10, as the perimeter of the smaller square is 10 inches bigger than one side of the larger square.
We're going to solve this question using simultaneous equations. This means we need another equation to compare the first one to.
Since we know that one side of the larger square is 2 inches bigger than the first one, we can make the equation
y = x + 2
Know that we know the value of y in terms of x, we can introduce this value to the original equation to find:
4x = (x + 2) + 10
Therefore:
4x = x + 12
3x = 12
x = 4
Now that we know the size of the sides on the smaller square, we can figure out the size of the larger square by using our second equation (y = x + 2)
y = 4 + 2
y = 6
Therefore, the length of each side of the larger square is<u> B.6</u>

I need help with this question please
tatuchka [14]

Answer:

y=1/2x+4

Step-by-step explanation:

To find the formula of a line with slope intercept form, you need to know the slope of the line and the y intercept (where the line crosses the y axis, or where x is 0). The y intercept is visibly at (0,4). To find the slope of the line, you need to find how much the line "rises" in a certain amount of "run". You can see that the line moves two to the right for every one unit it moves up, meaning that it has a slope of 1/2. Plugging this into the slope intercept form, or y=mx+b, where m is the slope and b is the y intercept, you get:

y=1/2x+4

Hope this helps!
