Answer:
32 trips.
Step-by-step explanation:
It's a proportion question.
7/84 = x/384
84x = 7*384
84x = 2688
Divide both sides by 84 to isolate x.
x = 2688/84
x = 32
So, Sarah will have to make 32 trips to cycle a total of 384 kilometers.

Answer: you do not need a variable when multiplying fractions and mixed numbers
Step-by-step explanation:
What is 4.312 x 100
any decimal times a multiple of 10 means that the decimal will move to the right based on the number of zeros
therefore
4.312 * 100 = 431.2
hope this helps
Answer:
431.2
Step-by-step explanation:
[tex] \\ 4.312 \times 100[/tex]

6 and 1 over 7?
Answer:
43/7
Step-by-step explanation:
6 1/7
First, you need to multiply 6 by 7, then add 1
43/7
Answer:
[tex]\frac{43}{7}[/tex]

6 x 7 + 1
there is 6 whole fractions so it would be [tex]\frac{7}{7}[/tex] 6 times then add the [tex]\frac{1}{7}[/tex]
which would be [tex]\frac{43}{7}[/tex]

Data for length of the tail (in millimeters) and age (in days) of tadpoles is entered into a statistics software package and results in a regression equation of ŷ = 15 - 1.5x.
What is the correct interpretation of the slope if the length of the tail is the response variable and the age is the explanatory variable?
Using the slope concept, it is found that the correct interpretation is that each day, the length decreases by 1.5 millimetres.
The equation of a line has the following format:
[tex]y = mx + b[/tex]
In which
m is the slope, which is the rate of change, that is, how much y changes when x changes by 1.b is the y-intercept, which is the value of x when y = 0.In this problem, the length of the tail, in millimetres, after x days, is given by:
[tex]y = 15 - 1.5x[/tex]
The slope is of [tex]m = -1.5[/tex], which means that each day, the length of the tail decreases by 1.5 millimetres.

The best definition of the term "reciprocal" is: A fraction that is the multiplicative inverse of the given fraction. The correct option is option B
What is fraction reciprocal?The reciprocal of a fraction is obtained by swapping the numerator and the denominator of the fraction. It is a number that, when multiplied by another number, results in a product of 1. For example, the multiplicative inverse of 2 is 1/2, because 2 × 1/2 = 1. In general, if a number "a" has a multiplicative inverse "b," then a × b = 1. However, not all numbers have multiplicative inverses.
Reciprocals are also knowns as multiplicative inverse. Multiplicative inverses are essential in various mathematical operations and concepts, including fractions and solving equations involving division.

Step-by-step explanation:
line st is the diameter so it equals 180º
so 3x-14+3x-14+2x+8=180 substitution
8x-20=180 combining like terms

Victor has 2 times as many as trophies as Dean. Together , víctor and Dean have 27 trophies . How many trophies does víctor have?
Answer:
Victor has 18 trophies
Step-by-step explanation:
Let's set up "let statements"
Let d = Dean's trophies
Since Victor has 2 times as many trophies as Dean, we can set up a let statement for Victor like this...
Let 2d = Victor's trophies
Now we can set up an equation! Since we know Dean and Victor have 27 trophies altogether...our equation has to involve addition...
2d + d = 27
Combine like terms...(2d and d)
3d = 27
Divide 3 on both sides to isolate the variable "d"
3d ÷ 3 = d
27 ÷ 3 = 9
So...
d = 9
That means Dean has 9 trophies. But we are not done yet because we need to figure out how many trophies Victor has. Since Victor has 2 times the number of trophies as Dean we can do...
2 · 9 = 18
Therefore, Victor has 18 trophies!
Hope this helps :)

Answer:
m - 19 = 58
Step-by-step explanation:
Knowing that the word "difference" relates to subtraction, you should know that the equation involves a minus sign.
The problem also tells us that 58 is the difference. Basically, the word difference means the answer to a subtraction problem. So 58 is the answer to this equation.
However, we are not done yet. It says to use "m" to represent Matt's age. Thus, we can write our equation as:
m - 19 = 58.
The variable "m" goes first instead of 19 because the answer would no longer be 58. For instance, let's say m is 18, 19-18 is equal to 1...not 58.
Therefore, the correct equation is:
m - 19 = 58

Slope is 1 and (-2, -1) is on the line.
Answer:
You can’t find the slope of a line if only given one point. If you had a visual representation of the line such as a graph or a table you could find a second point and then use the formula for slope, y = (y2-y1) / (x2-x1).
Imagine a single point on the xy graph. You could take a random point elsewhere from an infinite number of points and would be able to draw a line and find the slope. This means there could be an infinite number of different slopes for one point. One point on an unknown line is not enough information to determine the slope of its line without a graph or a table.
