<h3><u>Question:</u></h3>
The length of an object in feet is equal to 3 times its length in yards. The length of a waterslide is 48 feet. Write and solve a multiplication equation to find the length of the waterslide in yards.
<h3><u>Answer:</u></h3>
The length of waterslide is 16 yards
<h3><u>Solution:</u></h3>
Given that,
The length of an object object in feet is equal to 3 times it’s length in yards
The length of wall water side slide is 48 feet
Let "y" be the length of object in yards
Write and solve a multiplication equation to find the length of the waterslides in yard
From given,
Length in feet = 3 times length in yards

<em><u>Therefore, the multiplication equation is:</u></em>

Solve the equation for "y"
Divide both sides of equation by 3

Thus length of waterslide is 16 yards
if you meant x^2+9x+20 then it is (x+4)(x+5) you know that because 4+5=9 and 4x5=20 using FOIL
Answer:
A=152
K= -Ln(0.5)/14
Step-by-step explanation:
You can obtain two equations with the given information:
T(14 minutes) = 114◦C
T(28 minutes)=152◦C
Therefore, you have to replace t=14, T=114 and t=28, T=152 in the given equation:

Applying the following property of exponentials numbers in (II):

Therefore
can be written as 
Replacing (I) in the previous equation:

Solving for k:
Subtracting 190 both sides, dividing by -76:

Applying the base e logarithm both sides:
Ln(0.5)= -14k
Dividing by -14:
k= -Ln(0.5)/14
Replacing k in (I) and solving for A:

Dividing by 0.5
A=152
Let Sara weight =x+25
amber wiegh =x
x+25+x=205
x= 90
Sara weight is 90+25= 115
Answer:
Step-by-step explanation:
y = mx +b
Here , m is the slope and b is the y-intercept
y = (1/2)x - 3
y-intercept = -3
