Step-by-step explanation:
Answer:
D(12) = 2,600 miles
It means a distance of 2,600 miles is already traveled from home after 12 hours
Step-by-step explanation:
To find D(12); all we have to do is to substitute the value of 12 for D
We have this as;
D(12) = 3260-55(12)
D(12) = 2,600
In the context of this problem, what this mean is that the distance away from home is 2,600 miles after traveling 12 hours
Answer:
B) 8 cm
Step-by-step explanation:
Hello, I can help you with this
according to the question
The length of a rectangle is 3 cm greater than the width of the rectangle.
convert this into algebraic terms
Step 1
do the eqution
Let
W,width
L,Length
The length of a rectangle(L) is(=) 3 cm greater than the width (W+3) of the rectangle.
note:3 cm greater than the width (W+3) means that you need add 3 to the width to obtain the length
L=W+3 equation(1)
the area of the rectangle is 40 square cm
Let
A,Area
Area= 40 cm
A=40
also,A=L*W
40=L*W equation(2)
Step 2
solve the equations
L=W+3 equation(1)
40=L*W equation(2)
replace the value of L from equaiton (1) into equation (2)
we are looking for a distance, so we need the positive valur only.
Step 3
Now, replace the value of W into equation (1) to obtain the length
L=W+3 equation(1)
L=5+3
L=8
so, the length is 8 cm, B) 8 cm
Have a nice day.
