Answer:
[tex]r=160-12m[/tex]
Step-by-step explanation:
Heart rate will be represented by [tex]r[/tex], minutes will be represented by [tex]m[/tex].
Here's the equation I came up with:
[tex]r=160-12m[/tex]
We can also rearrange it to look like a point-slope equation. Either way works, it's the same equation.
[tex]r=-12m+160[/tex]
This works because her heart rate is decreasing by a constant value. The initial heart rate is like the y-intercept, while the amount that it decreases by is the slope.
I hope this helps!
The equation is y=160-12t where t is the time in minutes.
What is a linear equation?The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.
Given here, After sprinting, Emilie has a heart rate of 160. As
she cools down, her heart rate falls by 12 beats therefore, we can form the equation as if the time is t minutes of cooling down then we can the heartbeat at a given time as y=160-12t
Hence, the equation is y=160-12t where t is the time in minutes.

[tex]d=\frac{147}{6.3}[/tex]
Step-by-step explanation:
The right side is a ratio [tex]0.84:\frac{7}{15}[/tex] a ratio can be written as a fraction [tex]\frac{0.84}{\frac{7}{15} }[/tex] this means [tex]0.84[/tex] divide by [tex]\frac{7}{15}[/tex] which is the same as [tex]0.84*\frac{15}{7}=\frac{12.6}{7}[/tex] On the left, change the mixed fraction [tex]3\frac{1}{3}[/tex] to the improper fraction [tex]\frac{10}{3}[/tex] Then divide [tex]0.3d-1[/tex] by [tex]\frac{10}{3}[/tex] which is same as [tex](0.3d-1)*\frac{3}{10} =\frac{3(0.3d-1)}{10}[/tex] So the equation is now [tex]\frac{3(0.3d-1)}{10}=\frac{12.6}{7}[/tex] Now multiply both sides by 10 and 7:[tex](10)*(7)*\frac{3(0.3d-1)}{10}=\frac{12.6}{7}*(7)*(10)\\7*3(0.3d-1)=12.6*(10)\\21*(0.3d-1)=126\\6.3d-21=126\\6.3d-21+(21)=126+(21)\\6.3d=147\\d=\frac{147}{6.3}[/tex]Answer:

4. A food delivery service charges a $100 membership fee to join, and also charges $5 for each delivery. Find the linear equation that models the cost based on number of deliveries. At the total cost of $200, how many deliveries will have been made?
Answer:
200-100=5(x)
Step-by-step explanation:
If the total cost is 200 dollars and we spent 100 on the fee, we have 100 dolars for deliveries.
If each delivery is 5 dollars, then the amount of money spent on deliveries is x(unknown) dollars then we have 200 - 100 = 5 x <--unknown

A rectangular tank has length 4m, width 12m and height 3.5..i. If the tank is filled with water 2/3 of its capacity ,calculate the volume of the water in the tank.
Answer:
The volume of the water in the tank is 112 m³
Step-by-step explanation:
The volume of the rectangular prism V = L × W × H, where
L is its lengthW is its widthH is its height∵ A rectangular tank has a length of 4 m, a width of 12 m, and
a height of 3.5 m
∴ L = 4 m
∴ W = 12 m
∴ H = 3.5 m
∵ V = L × W × H
∴ The volume of the tank = 4 × 12 × 3.5
∴ The volume of the tank = 168 m³
∵ The tank is filled with water [tex]\frac{2}{3}[/tex] of its capacity
→ That means the volume of the water is [tex]\frac{2}{3}[/tex] the volume of the tank
∵ The volume of the water = [tex]\frac{2}{3}[/tex] the volume of the tank
∴ The volume of the water = [tex]\frac{2}{3}[/tex] × 168
∴ The volume of the water = 112 m³
∴ The volume of the water in the tank is 112 m³

3 divided by 1/? = 18
Answer: ? = 6
Step-by-step explanation:
3 divided by 1/x = 18
3x= 18
x = 6
Answer:
3 divided by 1 equals 3
How :
We can write 3 divided by 1 as a ratio, fraction, or equation. Let's try writing this statement in all these ways
3:1
3/1
3÷1
The easiest way for me to solve this question is as a fraction so let's solve it like that. If the denominator is a 1, we immediately know that the answer is the numerator and that you don't need the denominator. so we can take away the 1 from 3/1 and that is how our answer is 3!
Hope this Helps!!! :)
Let me know in the comments if the answer was perfect or if I should change anything!!! :)

Reduce the Fraction: a(x-2y)/b(2y-x)
Answer:
[tex]\displaystyle-\frac{a}{b}[/tex]
Step-by-step explanation:
We have:
[tex]\displaystyle{\frac{a(x-2y)}{b(2y-x)}[/tex]
In the denominator, we can factor out a negative 1. This yields:
[tex]=\displaystyle\frac{a(x-2y)}{-b(x-2y)}[/tex]
We can now cancel out the factor. Hence:
[tex]\displaystyle=-\frac{a}{b}[/tex]

Evaluate the expression |2x – 5| for x = –3 and for x = 3.
A)
11, 1
B)
3, 13
C)
13, 3
D)
1, 11
Answer:
Option A: 11,1 is the correct answer.
Step-by-step explanation:
The absolute value is used in the given expressions.
The absolute value represents the values of a number or variable irrespective of its sign. This means that |x| = x and |-x| = 0
Given expression is:
[tex]|2x-5|[/tex]
Putting x=3
[tex]|2(-3)-5| \\= |-6-5|\\= |-11|\\=11[/tex]
Putting x=-3
[tex]|2(3)-5| \\= |6-5|\\= |1|\\=1[/tex]
Hence,
Option A: 11,1 is the correct answer.
